Down to Sleep; Up to Eat Lance XRV Update 30 March 2025

Down to Sleep; Up to Eat Lance XRV Update 30 March 2025

Wow!  Another month races into the history books and the progress on Lance continues.
Down to Sleep; Up to Eat Lance XRV Update 30 March 2025We continue to enjoy the almost always sunny weather here in the deep south of Nevada though being at just over 3800 feet elevation it was still cool temperatures for much of March but warming up more and more each day now as April approaches.  This is pretty much “Wayne’s World” these days with my table saw, drill press and chop saw set up alongside Lance in between the two 40’ shipping containers. 
As you might notice, I share this space with my buddies Zoe & Razz who enjoy their “grassy patch” and outdoor play pen supervising my work most days.

PXL_20250223_200032790This is about where things were at the end of February and my last update, with the XAL (eXtruded Aluminium) framing in place at the front end of Lance’s Happytat where the Head/Bathroom and Shower areas will live.  The cabinet on the far Right here alongside the side door and entryway will be where the fridge/freezer unit goes.
PXL_20250226_193935723To max out volume of storage areas I framed in the space above the Joolca “Gotta Go” separating toilet to create an overhead cabinet.
PXL_20250226_193944919.MPI’ll divide this cupboard into two areas with storage in the front area and have a smaller second area behind it where I’ll mount the thermostatic shower control, hose and showerhead.  
PXL_20250226_193956819As you may have noticed I am working my way counterclockwise around the interior spaces and the last part of the main framing for the primary cabinetry is the currently empty area on the far Left you see here, which will be the Drivers Side Galley.
PXL_20250308_014327151I continue to enjoy building all the cabinet framing with 10 Series or 1 inch square eXtruded Aluminium (XAL) and it all goes together relatively quickly having done all the design work as I built the 3D model, hence the ever present laptop running Fusion 360.


Good time to also check the fit and placement of the deep double sink with its great views out the window when washing dishes.
PXL_20250308_014332237The model gives me the precise length of each piece I need to cut on the cut off saw and how each joint goes together.  Each of those four vertical spaces will be filled with drawers of different heights and the vertical XAL front and rear provide very strong attachment points for all the undermount drawer slide hardware that I’m about to order.
PXL_20250314_173019105.MPSpeaking of windows, we have our always alert security guards keeping a close eye on the comings and goings of the various others we share this fabulous area.  No need for any worry about our safety with these two vicious watch dogs on the job!
Wiley Cayote   RoadrunnerWhile we don’t see too many people, which is just the way we like it, there is lots of life to see out our windows including the real life versions of Wile E. Coyote & Roadrunner, rabbits large and small, lots of mice and squirrels on the ground and ravens overhead.


PXL_20250308_014419443Very much a work in progress as you can see but the interior spaces are starting to take shape now.  This is taken with me standing in the shower area at the front with the main entry on the far Left, the now completed Drivers Side Galley countertop on the far Right that is 175 cm / 5’ 9” long and a matching countertop opposite that will be 98 cm / 3’ 2” long. 
Bed UPNow my attention turns to building the lifting bed platform which is atop the L shaped settee that occupies the area aft of the two countertops.  Most of the time the bed platform and mattress will rest as you see here, gently squeezing the mattress up tight against the ceiling with plenty of headroom for sitting underneath in the settee.

Bed platform   LiftsHere is a skeleton view of the XAL bed frame in Blue which will then have a plywood panel spanning across the support bars with the mattress tucked firmly inside the outer XAL bed frame.
Bed DownFor sleeping, the full size Queen bed lowers down, along with the Settee table, to this easily accessed position.  This setup makes it easy to make up the bed every morning and then have it retract fully out of the way with just the push of a button.

 


PXL_20250318_012117581No magic tricks required for this!  Instead I’m going to install four of these PA-18 Linear Actuators I’ve had built by a Canadian firm in Vancouver; Progressive Automation.

If you look closely (click to enlarge any photo) at the renders above you can see these located at each corner of the bed frame and you can see here how the one on the PS Front is bolted to the two vertical lengths of XAL at the end of the PS Galley countertop.
PXL_20250318_210549435All four actuators plug into this FLTCON-4 central control box which provides the 24 volts for each motor. 
PXL_20250330_204118494Inside the long aluminium body of each PA-18 linear actuator is a threaded stainless steel rod which is driven by the black motor at the top which in turn causes the black “Car” below it to move up or down the full length of the AL track. 

 


PXL_20250330_204354734Last piece of this automated lifting bed system is this small set of buttons that is also plugged into the control box.  Once the interior panels are all installed this will be the only part you will see and will likely be mounted somewhere out of the way but easily reached when we want to move the bed Down to Sleep or Up to eat.
PXL_20250330_204416837The Up/Down buttons allow you to move the bed Up/Down to any position you want and then you can save this position into memory of button 1, 2, 3 or 4. 

Now anytime you press that number, the bed automagically moves to that position.  
I will likely program #1 to move the XAL bed frame to the max UP position without the mattress in place whenever I’m working on the bed system and want the platform completely up out of the way.  Then #2 can be the regular UP position with the mattress in place for whenever we are using the settee, #3 can be the Goldilocks position for best views out the window when in bed and 4 can be the lowest position for ease of getting in/out of the bed. 
PXL_20250318_210602922To ensure that the positions of all four actuators are synchronized there is a Hall Effect sensor inside each actuator which communicates the position of each sliding Car to the control box. 
Here I have all four actuators plugged in so I could test the “synchro” feature which causes all four cars to go to their Home position with all Cars in their max Up position and then I could also test out the memory setting feature before I installed each actuator.

My next challenge was to figure out a way to connect the sides of the XAL bed frame to the four sliding Cars on the linear actuators such that they would move the bed frame would move Up and Down. 

Hmmmmm ……..

 

PXL_20250318_220559896.MPI work hard to maintain my well deserved reputation as a pack rat and so I had kept ALL the wires, materials, nuts, bolts and hardware when I fully gutted the original Horton ambulance box and took it down to the bare AL frame.  One of the pieces of aluminium I kept was this C-channel and it turned out to be my just right Goldilocks solution for building the saddle blocks I would bolt to the cars on the actuators.
PXL_20250318_220537014I cut the C-channel into four short pieces that were the same length as the Black Cars on the actuators.
PXL_20250318_223753358The width of these Black Nylon Cars was just a wee bit larger than the inside width of the AL C-channel so I carefully guided each actuator through my table saw and trimmed off about 2mm from each side.
PXL_20250318_223734619.MPWhich allowed them to be a slight press fit onto the Car.
PXL_20250318_223819357The inside corners of the C-channel have a radius to them but it was easy to file the corners of the Nylon Cars to match and Voila!  A perfect fit.
PXL_20250320_220438760Progressive Automation manufactures the thick Black Nylon Cars with three threaded mounting holes on each side which go all the way through the body of these Black Cars; a large M10 in the middle with two M6 on either side, so I drilled out matching holes in the sides of the AL C-channel saddles so I could very securely attach each saddle its Black Car mate.

Next question was how to attach the XAL bed frame to these Nylon & AL saddles?  This would need to strong enough to safely transfer the full combined weight of Christine, Zoe, Razz and me as well as weight of the bed XAL frame, cross member, panels and mattress but could not be a solid unmoving connection.  It needed to be allow for a bit of rotation for any slight changes in orientation as the bed frame travelled up and down the full stroke length of about 110 cm / 44 inches.

Hmmmmmm ……


Heim JointsI decided to use what are called Heim Joints which as pictured here are typically used to join the ends of connecting rods on things like steering links on vehicles and industrial machinery.  These are made for eXtreme loads made of heat treated steel plated with hard chrome and readily available from Amazon.  I’ve used these with great success in projects for probably 50 years and they’ll be a good fit here as well.
Heim Joint partsI ordered four of these 3/8” Heim joints which are rated for a load capacity of 4,400 Kg/9,544 lbs.

and come with their matching SS threaded inserts and jam nuts. 
PXL_20250320_223038216.MPI used the same scrap of C-Channel to cut four more pieces and cut each of those in half ………..
PXL_20250321_004341298…….. to make these matching L-bar mounting brackets ………..
PXL_20250322_204900721………. which I then bolted to the C-Channel saddles with the Heim Joint sandwiched between the two “ears” of the brackets and through bolted.
PXL_20250328_010101847.MPWorked very well and I could then bolt each Heim Joint Saddle to its matching Nylon Car.  I then bolted each linear actuator to the vertical XAL support posts using some AL bar stock that I cut to be thick enough to keep the inner surface of the AL saddles spaced clear of the inside of the XAL posts and they moved up and down.

Final part of this puzzle was to mount the SS threaded inserts for each Heim joint you can see here, to the sides of the bed frame.
PXL_20250329_014210676 The sides of the bed frame are made from lengths I cut from 3” x 1” XAL and carefully clamped each one in place so I could precisely mark the center of each SS insert and then I drilled undersize holes through the XAL.  As you can see in the photos above these SS inserts are tapered so I used my handy dandy Dremel tool with a rotary carbide cutter to enlarge these holes and carefully hand fit the SS inserts to be a slight press fit into the XAL.
PXL_20250330_204223244I will likely build different corner brackets to join the four sides of the bed frame but for now these 90 degree corner brackets will work to lock the frame square and true while I finish mounting the frame to the four Heim joints.
PXL_20250330_204313174I allowed about 5mm / .2” clearance between the moving bed frame sides and the XAL posts so it is a very close fit that was relatively straight forward to adjust by turning the threaded SS inserts with a wrench on the flats I ground on each one (see photos above).
PXL_20250329_014152519The power/comm cables on each actuator need to be extended but I was able to just plug each cable into the control box and hang it in the center which allowed me to test out the whole assembly. 

Best of all ………………… IT WORKED first time!!  I was able to raise and lower the bed and set four memory positions to the numbered buttons and it all moves up and down smoothly and quietly. 
We are eXtremely happy with this design as it gives us have a full Queen sized memory foam bed without giving up any space for seating or eating.  And also eliminates the need to set up and make up the bed every night and repeat it all every morning.
PXL_20250330_222304398Last update to show you today is that we were able to temporarily slide the fridge/freezer into its home!

This is an Isotherm Cruise 200 that runs off both 12VDC and 120VAC


PXL_20250330_222324297Total of 7 cubic feet with a 5.3 cubic feet refrigerator and 1.78 cubic feet freezer – each with their own separate side by side doors. 

Will go a long way towards enabling us to have plenty of food to go a long way and stay out there a long time.  Can’t wait to start using it.

That’s a wrap for this update and my sincere thanks to all of you brave souls who have persevered and made it this far!  Probably waaaaaaay too much detail for many of you but hopefully easy enough to scroll through at whatever pace you like.

IMG_5206I’ll leave you with these photos that Christine is so good at taking of the views out our dining room window most evenings here on Road Runner Ranch.

It is difficult to make out in these photos but the Colorado River is running just in front of the mountains you see off in the distance here.

 



IMG_5207The light at this time of day as the sun is just setting below the mountains behind us makes for some truly spectacular ends to our days we are so fortunate to enjoy most every day.
Hope you enjoy and will look forward to answering any questions or comments you leave in the “Join the discussion” box below.

Batteries, Bathrooms & Birthdays:  XRV Lance Update 23 Feb 2025

Batteries, Bathrooms & Birthdays: XRV Lance Update 23 Feb 2025

I always liked the John Lennon line from his Beautiful Boy song in 1980 that “Life is what happens while you are busy making other plans” and that’s a good summary since my last update here.  It has been a very busy and fun six weeks with no shortage of projects, trips and milestones but not so much time for updates so thanks for your patience.
Batteries, Bathrooms & Birthdays:  XRV Lance Update 23 Feb 2025Two birthdays in January, one for me on the 23rd and daughter Lia on the 14th.  So we decided to make the relatively quick drive, less than 4 hours, over to the LA area to surprise Lia on her milestone Four Oh!birthday by delivering some some B’day flowers, champagne and hugs in person.  As a bonus we went back for a week to see Brynn’s Talent Show at her school and then got to be full time Gramma and Grampa for the weekend while Brian & Lia had a fully unsupervised weekend away for Valentine’s Day. 
dji_fly_20250111_155122_48_1736639515247_photo_optimizedWe continue to work away at getting things setup here on “Road Runner Ranch” and this arial shot from Christine’s drone video that you might have seen in the previous post, shows how we are setup so far. 
PXL_20250121_173048321The 40’ shipping container above on the left is what I’m setting up for my workshop with Lance parked right beside. 
PXL_20250128_211810964The matching container on the Right is what we’re using for storage and is close to our 25’ travel trailer that continues to provide a very comfy home for us and the two pups for now. 

We recently got a good deal what they refer to as a “garage fridge” so we’ve now got that set up inside this container to expand the fridge and freezer space that is built into the trailer and keeps us well stocked in food supplies.
IMG_5124This panorama shot (click to enlarge any photo) will help you get a sense of the setting we’ve got for our little sanctuary here and might help some of you make a bit more sense of why this is such a Goldilocks location for us.

Best news for me and many of you who I know have been waiting, is that I’m back to working on converting “Lance” our 2017 Kenworth ex medium duty ambulance into our eXploration RV.  I’ve picked up where I left off building all the cabinetry framing using lengths of eXtruded ALuminium which I’ll abbreviate as XAL.
PXL_20250201_003958494Looking forward from about mid way inside Lance’s “Happitat” the blank wall on the left is the front wall with the cab on the other side and the main entry door that is on the passenger side PS in the right corner.  I’ve put in a scrap of 3/4”/20mm plywood to create a desk for myself on what will eventually become one of the two galley countertops with a larger one yet to be framed on the opposite left or driver side DS. 
The XAL you see on the ceiling is where the forward side of the lifting Queen bed will go with a large L shaped settee below.
PXL_20250202_011422658Here is a sample of a length of the XAL with several different corner brackets that bolt into the T track grooves in the XAL which turn this into a giant adult version of the Erector sets I used to love playing with as a young boy, long before many of you were born!
PXL_20250203_013202928I’m working my way somewhat counter clockwise around the Happitat walls so my next focus was the XAL framing you see now in the front right PS corner.  The Blue poles you see ratcheting cargo support bars that have proved indispensable to me for holding things in place as I build.
PXL_20250204_201448087This full height cabinet will have our fridge/freezer mounted inside the large opening you see here with lots of storage in the spaces above and below. 

Shower will be in the middle on the left here and the head/toile over in the far left DS corner that I’ll move onto next.
PXL_20250220_214317790.MPThis front DS front corner is a bit more complex as the large vertical exterior access cabinet is also in this corner and it is where I’ll be installing Lance’s whole electrical system with three large lithium batteries on the very bottom and then all the other components such as 12VDC to 120/240VAC inverters, battery chargers, and much more mounted this exterior locker. 

Here on the inside is where I now need to finish the XAL framework above the battery frames I’ve built to support the three big batteries.
PXL_20250220_214559556.MPThis will give you a sense of the size and shape of the server rack style lithium LiFePO4 batteries that will provide all the 12VDC and 120/240VAC electrical power in Lance. 
EG4 51.2kW battery labelFor those interested in the details, this shot the label on one of the three batteries will give you all the numbers.

While 45Kg/90 lbs might sound like a lot when you consider that each one of these provides 5120 WattHours (400Ah @ 12.8VDC) the power density is pretty amazing.   Having three of these connected in parallel will provide a total of 15.36Kwh (1200Ah @ 12.8VDC) which will will be more than enough to give us all the power we need for our all electric cooking appliances such as induction cooktop, coffee makers, toaster oven, microwave as well as powering our mini split Air Conditioner. 
Batt box   Joolca XAL framingAs with all of this build, I had created very accurate 3D models using Fusion 360 of all the XAL framing and each of the components such as this Joolca separating toilet and the EG4 batteries and these have served me very well throughout the build. 

 


PXL_20250220_230836997I knew that the batteries were going to be a very close fit and I had built the framing for them back when we were in Klamath falls but now was the moment of truth to see if they actually fit?!! 
PXL_20250221_013906457.MPThe “ears” of the server rack batteries were a few millimeters wider than the opening of the door frame so it took a bit of wiggling them in at an angle and some gentle persuasion, ……..

 


PXL_20250221_014139957……. but they fit in snug as a bug in a rug as you can see here and put a big grin on my face.

 


 PXL_20250221_202413928These server rack style of battery are very safe and easy to work with as they have both an On/Off switch (silver circle upper right) that turns the BMS (Battery Management System) on/off as well as the high amp double pole high amp circuit breaker (White/Blue on bottom left) so I could keep bot of those turned Off and ensure that there was never any danger of a short to the terminals while I was wrestling them in place.
PXL_20250221_014353049Locating the batteries in this front DS location was ideal as it kept the weight down low, centered and on the opposite side from the fuel tank and also enables me to keep all the electrical system components in this one externally accessible locker. 

However it did require me to raise the floor and design around them on the inside as you can see here.
PXL_20250223_200127814After playing around with the 3D model for some time, I ended up making this raised area inside be just the right height for the floor under the Joolca Gotta Go separating toilet.
PXL_20250223_200051345With the shower area in the center area the whole bathroom space becomes feels very large and open both when using it as a shower and when seated on the throne.  I had my Beautiful Bride check it all out in person this morning and got the two thumbs up so the framing progress can now continue.
IMG_5064I also checked in with these two scallywags, Razz on the left, Zoe on the right, and got their approval as well so I’m all systems GO now.

So I will continue to work my way around the DS corner as I move onto framing out the Galley/Kitchen area that runs down the rest of the Drivers Side and you’ll see that in the next update. 
IMG_5121We continue to get sunsets like this almost every evening and sunrises are pretty spectacular as well so we continue to enjoy our new location a bit more each day.
That’s a wrap for this update and I’ll do my best to post the next one much sooner and try to get back to doing one every Sunday as long as “life” doesn’t interfere!

Hope you enjoyed the update and thanks to all who persevered to this point.  Be sure to add all your questions and comments in the “Join the discussion” box below and hope you’ll be back for more in the next update.

New Year–New Home Base – Lance XRV Update 12 Jan 2025

New Year–New Home Base – Lance XRV Update 12 Jan 2025

As predicted when I left off in the last update here, it has been a VERY BUSY time the past month for us but we’ve made the move and are now settling into our new Southern Home Base down near Searchlight Nevada. 

There are some photos and details about our new 10 acre property in that PREVIOUS POST back on Dec. 8th so you can check that out if you’d like and I’ll just pick up from where we left off.

BONUS:  Be sure to read to the end to see the bonus video that Drone Captain Christine put together.

 

Our son Skyler flew down from Vancouver BC on the 23rd of December to join us for the holidays in Klamath Falls and he was a HUGE help getting all my tools, equipment, materials and such packed up from the workshop I’d set up in Klamath Falls.  Along with our personal belongings and food we managed to get everything loaded into Lance and the beds of the two pickup trucks we now find ourselves with. 

New Year–New Home Base – Lance XRV Update 12 Jan 2025

We were a bit sad to leave as we had really enjoyed our time getting to know Klamath Falls and the surrounding area of southern Oregon.  This is the parting shot just after noon on Boxing Day (Dec 26th) as we bid a very fond adieu to what had worked out to be a great home and workshop and hit the road for the almost 700 mile drive down to our new Southern Home Base just north of Searchlight NV.
We broke the trip up into two legs with an overnight stop in Fallon Nevada and it turned out to be a great drive with clear dry roads after we got about a hundred miles south of Klamath Falls and enjoyed the ever increasing temperatures as the miles rolled by. 
IMG_4937We arrived at the property late in the afternoon of the 27th with big smiles for all three drivers and both pups.
IMG_4936And just in time to catch this beautiful sunset which we’ve now discovered is most every night here.

dji_fly_20250111_155138_49_1736639515959_photo_optimizedChristine has been getting her drone flying skills dusted off and this shot she grabbed a few days ago from up above the spot we’re setting up to live on for the next few months will give you an idea of the layout.  Those two big white rectangles are 40 foot “High Cube” (9’6” high) shipping containers that came with the property along with a lot of great items inside that you’ll soon see.  The other white rectangle is the 2012 25 foot travel trailer that will be home for us for now.

     ** See the Bonus drone video at the end.
IMG_4951As Skyler and I unloaded the crates of our belongings and coolers of food, Christine got to work storing it all away and organizing our new home.  As sharp eyes might notice, she even baked a loaf of banana bread!
IMG_4953Looking aft in the trailer you can see that we’ve got everything we need with a nice U shaped settee and an adjacent full bathroom & shower.  Then a separate bedroom in the rear with a Queen bed and even an office for Christine to work at just out of sight in the rear left corner here at the foot of the bed.  And check out our views out the windows!
Lance 2385 floorplanThis floorplan helps to show how the bedroom & settee are in a slide out section along the right side of the trailer that really helps open up the space. 

Keeping in mind that we are both used to living full time in boats, for us this is HUGE!


PXL_20241229_003759706Skyler started unloading all the crates and materials from Lance and I started to figure out where to put them for now in the two containers.  The one you see here on the Left will be my workshop area and the other one out of site in this photo over on the far Right closer to the trailer provides storage for everything else AND houses all our fresh water and electrical power equipment that allows us to live 100% off grid.
PXL_20241229_003824518.MPCould not have been a better present than all the time we got with Skyler and all the hard work he so cheerfully gifted us with to make this latest transition of the Nauti Nomadic Grandparents so memorable.
IMG_5011Thanks Sky!

 


IMG_4949It will take me awhile to build workbenches and storage racks but for now all my tools and equipment are very safely stored away inside the two containers.

 


IMG_4944Part of what made this property such a Goldilocks just right find for us was that one of the things inside the containers was sixteen 305 Watt solar panels and so Skyler and I got to work setting those up in two different locations to try out for now.  Eight of those solar panels we propped up against the wall of the container as you can see here which made it a short run for the power cables to go into the MPPT controller inside. 
Of course the HIGHEST priority was getting the new Puppy Play Pen set up for Zoe and Razz to enjoy.
IMG_4946The other eight solar panels we propped up against the south facing side of the trailer to try out that orientation as I monitor the daily production to see what generates the most power to keep our big new battery bank fully charged every day.

All very rough and tentative till we live with all this for awhile and decide best location on the acreage to build on and then I will build proper ground mount racks for all these and perhaps more solar panels.
PXL_20241203_212529534In that previous post you may recall seeing this pallet full of boxes that had arrived at the Klamath Falls workshop which contained the other two key components of our off grid power system.
EG4 WallMount_Indoor_2__41001this 15 kWh 54 Volt upright EG4 lithium battery and ……….
EG4 6000XP…….. this EG4 6000XP  all in one MPPT solar charge controller, inverter charger. 

 

 


IMG_4945The battery weighs a svelte 128kg/282 lbs. but Skyler and were able to get it wrestled out of Lance and into the container and get the 6000XP mounted above it and all secured to the steel walls of the container. 
PXL_20250101_164530953These two smaller vertical boxes I mounted on on the side at the mid point are the isolation switches and circuit breakers for the high voltage power coming in on the Red and Black wires you see here which come from each of the two strings of solar panels (8 panels in each).  We soon had everything wired up and in this shot I’m busy configuring all the settings before turning it on for the first time.  Just amazing how far these kinds of off grid systems have come and we were able to go from no power at all when we arrived to having a full 240VAC split phase power system in less than one day.
We had about 190L/50 USG of fresh water that I had filled up the trailer’s water tank with on my way bringing it back from where we bought it in Tucson so we had plenty of potable water for drinking, cooking and showers the first few days but now time for a more full time setup and another part of what made this property such a great find for us. 
PXL_20241115_220027798.MPThese four 1250L/330USG IBC Totes as they are called (Interim Bulk Containers) also came with the property along with a fifth empty one that we’ll use in the future to bring more fresh water from the town water system in Searchlight that is just a few miles away.  The pumps you see at the bottom here are now all set up to provide pressurized fresh water to a tap on the outside of the container and a hose from there to the trailer provides all the fresh water we need for day to day living.

 

 


It will take us a bit longer to get everything setup and be able to get back to working on books and Lance but we’re off to a great start and new year.

 

Can’t be all work and no play so in the midst of all this we also took time to celebrate the new year in our new home base. 
Immersive Van GoghChristine and I adopted giving “experiences” rather than “stuff” to each other for gifts and this year I got us three tickets to go see the “Immersed in Van Gogh” experience in Las Vegas on New Year’s Eve which is less than an hour’s drive north from our property.

 


IMG_4963Then Christine had rented a boat for the three of us to go out on Lake Mohave for New Year’s Day. 
IMG_4947This shot is looking about due East from our place and off in the distance about center (click to expand any photo) you can see the Colorado River flowing South.  Hoover/Boulder Dam is to the North and Davis Dam to the South which creates Lake Mohave in between.  It only takes about 15 minutes to drive from our place to the marina on Lake Mohave. 
IMG_5026I will leave you with this shot of what our humble new abode is looking like with yet another super sunset that Christine loves to photograph.


PXL_20241229_011954514I know many of you are shaking your heads and wondering what drew us here but perhaps these two days with New Years eve in Las Vegas and then New Year’s Day out on the lake both being minutes away from our otherwise eXtremely remote spot might help you understand a wee bit better what makes this such a Goldilocks place for us.

Location, location, location right??!!

BONUS VIDEO:

As promised, here is a short video that Christine has put together as she dusts off her drone flying skills for this quick flyover what we are thinking of calling “RoadRunner Ranch”.  Although we have not yet spotted one here yet I hope this quick flyover part of our 10 acres will help you visualize this location and maybe help you see what we see.  In any case do enjoy and thanks Captain Christine!

 

Hope all of you have 2025 off to a great start as well and I’m looking forward to getting back to regular updates in the next few weeks as I get my new workshop up and running and get back to working Lance.  Thanks for joining us on yet another adventure and please leave any questions or comments in the “Join the Discussion” box below.

Thanks!

Traveling Transition Time Again – Update on Lance XRV 8 Dec 2024

Traveling Transition Time Again – Update on Lance XRV 8 Dec 2024

As I mentioned at the end of the previous post, both Christine and I have been traveling the past few weeks.  Christine flew out to Florida for two weeks for some much needed Gramma time with our now 9 year old Grandson Liam and some time with her best friends and family in the Fort Lauderdale area.  And I flew over to Tucson to pick up the new to us travel trailer and pickup truck combo we recently purchased to provide living accommodations on our new 10 acre property near Searchlight Nevada. 

So this will just be a quick update on what little work I have been able to get done on Lance and a brief summary of what’s been happening as we start making the transition from our rental here in Klamath Falls down to our new Southern Home Base just north of Searchlight.

 

Traveling Transition Time Again – Update on Lance XRV 8 Dec 2024

This sat view (click any photo to enlarge) of the southern arrowhead tip of the state of Nevada (NV state border is dotted red/white line) might help show you where we’re headed.  Up in the top middle you can see the sprawling Las Vegas/Henderson area and Hwy 95 running parallel to the Colorado river heading South to the Laughlin/Bullhead City area at the bottom. 
Our new place is where you see the Green circle with the white flag about half way down Hwy 95.
Hwy 95 to Searchlight property sat viewZooming in a bit you can see the turn off of Hwy 95 onto the dirt road running East in the middle of this sat view over to our place with the Green Flag.  That distance is about 1.5 miles/2.4km

 


Searchlight property sat viewZooming in on that Green Flag, here’s the birds eye view of our 10 acres where you can see the two white shipping containers that came with the property.  (the boat was just being stored there)


Joshua_Tree_01For the curious amongst you, all the black dots you see in these sat photos are Joshua Trees so we are literally living in a Joshua Tree forest!

WhatsApp Image 2024-11-14 at 13.08.08Meanwhile, IRL In Real Life, here is where I put our Lance home on wheels #2 (too funny right?!) after the drive from Tucson. The truck is a 2006 Toyota Tundra SR5 and the trailer is a 2012 Lance model 2385.  For more details on Lance #2 the travel tailer, see the previous post for photos and layout.
And yes, other than several hundred Joshua Trees that is ALL there is so far on our 10 acres.  Many of you have sent a LOT of questions as to just what we are going to do for little things like power and water so here’s the deal on that.  Having lived in boats as we’ve been traveling the world for the past few decades, we are accustomed to being eXtremely self sufficient and this newest adventure will be no different.  

PXL_20241115_201806510.MPPart of the attraction and what made this property such a Goldilocks find for us was those two new containers AND what was inside of them.  Here is a shot of the container on the Left where you can see these 16 new solar panels.  These are 305 Watt PV panels which I will soon be setting up outside to give us a total of almost 5 kilowatts of potential solar power. 
PXL_20241203_212529534OK, so those solar panels capture the sun’s energy, but then what Wayne?? 

Well, the other parts of this puzzle which I need to build our completely off grid power station.are inside this trio of boxes that arrived here in Klamath Falls a few days ago.
EG4 WallMount_Indoor_2__41001Inside the wood box on the bottom is 128kg/282 lbs. of big beautiful battery power!  14.3 kWh (kilo Watt hours) to be exact, which comes in the form of our new EG4 wall mount 48V 280Ah lithium Iron battery.  Being in very sunny southern Nevada those solar panels should provide more than enough power to keep this battery fully charged every day.
EG4 6000XPThe two cardboard boxes above that contain this equally beautiful and important EG4 600XP split phase off-grid inverter/charger which handles two critical tasks.  First it takes all the 48 volt DC power from the battery and inverts it into 120 and 240 Volts AC and then there are two MPPT controllers inside which regulates all the DC power from the solar panels to charge the batteries. Together this will provide us with all our electrical power we need in the trailer and the workshop to power everything from air conditioner to induction cooktop to welder.

 


OK, so that looks after electrical needs, but what about water you ask?
PXL_20241115_200725197The solution to that also lies in the containers in the form of these IBC Totes (Intermediate Bulk Container) You may have noticed this one beside the 16 solar panels shown earlier.
PXL_20241115_220027798.MP~2Then there are four more ICB totes stacked up at the end of the other container.  There is a LOT of other equipment in these containers and I did a quick inventory of them after I took the trailer there and I marked this photo with the # of liters of fresh water in each one.  These ICB totes each hold about 330 USG/ 1250 Liters and so when all four are full that gives us about 1320 USG/5000L which should give us about a year’s worth of water.

What about that fifth empty one in the other container you ask?  Well, they are pretty light when empty and so we load that into the truck bed and head into town and fill it up with the “city water” from Searchlight which is just 2 miles south on Hwy 95.  Bring that back and use an electric water pump to fill the IBC totes in the other container.  Rinse and repeat once a year or so and we’ve got all the fresh water we need.
roof spanning 2 shipping containers sketchOur longer term solution is that we will use rain water catchment when I create a big workshop by moving the two shipping containers to be about 40 feet apart and build a large gable roof to span them a bit like this illustration. 
double hip roof with clerestory windowsI’ll do the roof a bit different to have clerestory windows on the peak but I’ll leave that for another post in the future. 

This large roof surface area will catch a LOT of rainwater that will be diverted into storage tanks in the ground.
So that’s the near and long term plan for water. Stay tuned here for more on all that as it gets built.

Back to Lance #1 and Klamath Falls, the other big beautiful shipment we recently receives is THIS!  Can you guess what’s inside?
IMG_4743……… Gold start to those who guessed it is the fridge/freezer combo for the galley in Lance.
IMG_4745Left side is a 1.8 cubic foot freezer and 5.2 cu ft of fridge on the right with plenty of shelves, drawers and door space so should serve us well.
PXL_20241128_192540039I’ve been busy getting Lance ready for the 800 mile drive down to Searchlight and needed to get all the lights on the back of him working.  I needed some wire for this and as you may recall from previous posts, I removed all the many miles of original wiring from inside the ambulance box and so with the help of my two assistants I tackled the sorting and spooling of all this wire.  This is Zoe with her “cone of shame” after her spay surgery.
PXL_20241128_015249603Together the three of us were able to convert this into ………………..
PXL_20241129_011457426……..… this and another tubful. 
PXL_20241118_153836273Twas a wee bit chilly doing this work for as the seasonal song goes ………. “the weather outside what frightful!”.  But I’ve got a little electric heater when I’m working inside Lance and with all his insulation it was doesn’t take much to keep it all nice and toasty in there.

The snow doesn’t last too long before melting away but the temps have been down below freezing at nights and some days for the past few weeks and so on that wintery note I will bid you all adieu and close out with what is likely to be the last blog this year.  Hard to believe that it was just over one year ago (October 12th, 2023) that we found ourselves on the dock in Portsmouth VA standing beside our beloved Mobiüs for the last time and beginning the transition from a life eXploring the world by sea to now doing so by land.  So quite fitting that as 2024 ticks over into 2025, we are now making the newest transition to Lance and our Southern Home Base.

Hoping all of you enjoy the upcoming holiday season and sending our sincere thanks for all the time you’ve spent following along with our adventures this past year or years.  Look forward to sharing more with you as the adventures continue into the new year.

Boxed In! Lance XRV Update 27 Oct 2024

Boxed In! Lance XRV Update 27 Oct 2024

Boxed In! Lance XRV Update 27 Oct 2024Yet another week without a lot of visible progress to show you, but all of our various shippers, USPS, FedEx and UPS were certainly busy as the pallets full of boxes with more and more the equipment we’ve ordered for transforming Lance into our new home on wheels continued to arrive here at our workshop/home in Klamath Falls. 

 


I won’t be able to install it all right away but we are hoping to move down to Nevada at the end of December and so we are trying to maximize the benefit of having no sales tax for the remainder of our time here in Oregon.  With the amount of equipment required to build a full self sufficient XRV, this really starts to add up to a significant savings and given the size of those bills, we take all the help we can get!
PXL_20241024_202654481Here is the most recent set of pallets that arrived on Friday. 
PXL_20241024_202704885These two pallets are from Current Connected with four 420 Watt solar panels on the Left and then the Victron inverter/chargers, MPPT controllers and EG4 batteries on the Right.  These are a bit fragile but they all arrived in perfect condition.
PXL_20241027_162548116I unboxed one of the EG4 12V 400Ah server rack batteries to check them out a bit closer and to get the exact dimensions so I can complete the XAL eXtruded ALuminium racks I’ve installed in Lance.  There are three of these monster batteries that I’ll wire up in parallel to create our 12V 1200Ah House Battery bank which gives us a whopping 15.4kW of overall capacity.  Even though we have gone mostly electric with all our systems other than diesel for our heating, our daily requirement will be much less than this but I’ve gone to this capacity so that we can stay remote for weeks at a time even with long periods of cloudy days with low solar output.
PXL_20241024_202646455These two Amazon boxes contain the new sink and induction cooktop for our new Galley aka Kitchen in Lance.
PXL_20241027_162620267This is the Empava 120V 1800 Watt two burner induction cooktop that Christine chose.  It will be built into the countertop but can also be removed and taken outside to create our outdoor kitchen in hotter weather.  Christine set this up here in the house and made dinner with it two nights ago and she gives it an enthusiastic two thumbs up!  We both much prefer induction cooking after our experiences with it on Mobius.
PXL_20241027_162655691This is the 28 inch dual SS sink.  It is a generous 245mm/10” deep as we both prefer big deep sinks.
PXL_20241027_162744761This one has some great features that extend its usefulness such as this wooden cutting board and a strainer that slide back and forth in the groove you can see at the top and bottom. 
Sink accessories 2There is also a drying rack for dishes that rolls up out of the way when not needed.
While there isn’t too much visible progress I can show you it isn’t for lack of hours and I have been busy with Fusion 360 working through the details in the 3D models I’m building for this project.
Galley layout screen grab FusionHere is a quick screen grab that I hope helps you visualize the interior layout.  Double sink in the Drivers Side Galley countertop up top and the induction cooktop on the Passenger Side. 
Lift bed layout screen grab FusionDinette is at the rear with lift bed above added in and then the Fridge/Freezer and AirCon in the PS front corner on the far Right here with the shower in the center and the Head on the Left behind the partially open red door.
LifeProof LVP flooring illustrationThe one bit of visible progress I can show you from this week is that I installed this finished vinyl flooring that I showed you last week. 

 


PXL_20241026_215808539Pretty straightforward process; peeled off the protective plastic layer with the blue arrows and then starting laying down the 8 inch wide click-lock planks.
PXL_20241026_224413357.MPIt is not the recommended practice, but I’ve decided to install this finished flooring first and then put in the framing for all the cabinetry as this will create a much cleaner install of the XAL eXtruded ALuminium framing.  We used this same type of industrial grade LVT planking in Möbius and were eXtremely happy with it so we stayed with what we know works. 
PXL_20241027_161952595We are thinking of using a darker wood for the cabinetry, Cherry or Walnut and so wanted to keep the floor a lighter colour.  If you look closely (click to expand any photo) you can see there is a wee bit of wood grain in this flooring which also provides a very safe non-slip surface that cleans up very well and is impervious to any spills or dropping of heavy objects.  Also very “dog friendly”!

 


PXL_20241025_202008524Razz and Zoe have been eXtremely busy as well as you can see from this shot of what is at my feet as I type!
And that wraps up another week and ………. unbelievably ……… another month!

Ciao for now amigos!

 


 


 


 


 

 

 

 

 

 


New "Super" House Batteries  Möbius Update 9 Sept. 2023

New "Super" House Batteries Möbius Update 9 Sept. 2023

The newest update to Möbius is that our all new House Bank batteries are now fully installed and up and running!

As you may recall from THIS post almost a year ago, our original FireFly Carbon Foam batteries had sadly lost most o f their “fire” aka capacity and repeated efforts using the FireFly prescribed “Restoration Charge” was not able to bring the capacity back.  Fortunately the combination of having a total capacity of 1800Ah @ 24V and our large solar capacity from 14 320W solar panels allowed us to go for almost a year of full time live aboard cruising running all systems other than extended AC use, without needing to ever plug into Shore Power.  So we did pretty well I think!?  But about a month ago while docked here in Norfolk, one of the four FF banks started to overheat and so their time was up.


New "Super" House Batteries  Möbius Update 9 Sept. 2023With our new situation (details if interested here) I had hoped that the FF batteries would last until we find the new owners and they take over so they could chose the new replacement batteries that were just right for them  But the “fire” had sadly gone out on the FireFly batteries and so I needed to make that call and have all new House batteries installed. 

For those interested, this post will give you an overview of how that progressed.


CHOOSING the GOLDILOCKS NEW BATTERIES

The quick summary of my requirements and priorities to determine the just right Goldilocks batteries for Möbius’ and our use case is as follows: (in no particular order)

  • WEIGHT:  Somewhat unique to us perhaps, weight is not a factor for choosing the batteries.  In fact we actually want/need as much weight as possible as we had designed the boat around the batteries to some extent and treated the 1022Kg/2250 lbs of FF batteries as part of the lead ballast of the boat.   
  • SIZE:  Battery size is also not a factor as we had to some extent designed the hull around the battery compartments which ended up being three large watertight and positively vented compartments which spanned and were centered on the 1″ thick x 18″ keel bar that runs from the transom all the way up to the top of the bow.  See the GA drawing below to see this layout.
  • WIDE TEMPERATURE RANGE:  Working well and safely within in as wide a range of operating temperatures as as possible.  Our intended use case for Möbius was to go everywhere from the Arctic/Antarctic and high latitude cccccccold climates to scorching hot locations. (which seems to be more and more locations in our world these days!)
  • FAULT TOLERANT:  In addition to temperature it was also important that the new House batteries were as robust as possible in that they would be able to deal with the typical “accidents” that happen over the years with the battery systems on boats.  Things like full discharges when the boat has been left for long periods of time and the charging system fails for some reason.
  • SAFETY:  Always a top priority of course but in the end I had no concerns with safety of either Lithium or AGM as I’m of the opinion that battery safety is all a matter of good design and installation of the electrical system and battery management, as well as sticking to top quality manufacturers.  So I did not consider any of the “off brand” batteries and companies.
  • VALUE:  Cost is an ever present factor for most of us but I think in terms of overall value rather than price alone.  I will gladly pay for quality and other features listed above to get the best match of batteries and our use case criteria.  I think this is well evidenced by all the equipment we have installed on Möbius.  So I did not consider any batteries or companies that were not IMO offering high quality batteries. 
  • EXTENDED 100% SOC + FLOAT TIMES:  This is a relatively new factor I have come to appreciate and which I believe may have contributed to the early demise of the Carbon Foam FF batteries.  Most of us have experienced how leaving things like laptops and phones plugged into their chargers and kept at 100% fully charged for most of the time leads to them loosing more and more of their capacity and shortening their lifespan.  I don’t have the expertise to prove this but my first hand experience over the years and my research into that of others has led me to suspect that there is a similar situation with LiFePO4 and Carbon Foam batteries. 

Due to our large almost 5KW solar power the batteries on Möbius sit at 100% fully charged state almost all the time.  With the large overall available capacity we typically only take the House batteries down to about 85% SoC or less between the end and start of each solar day and most days the solar charging brings them back to 100% fully charged by 10 to noon depending on solar conditions, time of year, geo location, etc.  You would think that this would be ideal for battery health.  However, I am finding increased evidence and examples that not only do LiiFePO4 and Carbon Foam type batteries deal very well with being in PSoC or Partial State of Charge for extended periods of time, they actually PREFER to be in a PSoC condition the majority of time.  Being kept in Float mode at 100% SoC can lesson their capacity over time.  It is possible to deal with this by carefully customizing the charging profiles of all the charging sources on the boat and our WS500 regulators for the alternators, MPPT controllers for the solar panels, and MultiPlus chargers all have this ability.  However based on my experience to date I think that AGM type batteries actually prefer to be kept at 100% fully charged SoC which is the situation as I’ve outlined above on Möbius.  I’m sure this factored to some degree in my final decision.

I should add that the rest of the equipment that forms the overall House Battery system would work well with any of the LiFePO4 or AGM batteries I considered.  Things such as the twin 250A 24V Electrodyne alternators with external rectifiers, WakeSpeed 500 Smart Regulators and Victron BMV712 battery monitors, would all work for any of the batteries I was looking at be they Lithium or AGM so this was a non factor in my decision making.  Lithium batteries would of course require equally high quality BMS either internal or external so I only considered LiFePO4 batteries with dedicated BMS from their manufacturer.

BATTERY CHOICES:

I’ve written about this topic of batteries for Mobius multiple postings here on the blog and I spent a LOT of hours discussing this with experts and other boat owners and researching the latest offerings of high quality batteries.  This lead me to narrow it down to a choice between Lithium (LiFePO4) and AGM batteries from the likes of Victron, Battleborn/DragonFly, Lithionics, etc. all of whom had some very high quality options.
Box
Dragonfly Battery Images (Transparent Background)For example, this new form factor of “12V 270Ah GameChanger 3.0” LiFePO4 batteries from DragonFly had some very attractive features.


Victron OPzV battery photoI also went back to the original batteries that I had considered for Möbius during the initial design phase which were these type of OPZv Gel type “traction batteries” and they were in the running again in this most recent search.
I paid close attention to how “bullet proof” the batteries were in terms of being able to deal with such factors as the likelihood of a few times in their long lifespan where they would end up being completely discharged for some reason or another.  Never planned of course but always possible and when we start talking about lifespans of 10+ years the probability of such “accidents” becomes quite high.

Lithionics batteryThese intriguing 24V 275Ah LiFePO4 “modules” with external BMS from Lithionics ticked off a lot of boxes were also recommended by OPE though came with a deservedly high price as well.
There were several other batteries and companies which I researched and made it onto my short list but the ones above cover the top contenders. 

and the WINNER IS …………..

I’m well aware that many of you would make a different choice for YOUR boat, but I do my best with all equipment decisions to find the “Goldilocks” just right choice that best matches with Möbius’ use case. 

In the end, this is what I chose; (drum roll please …………………….)


Victron SC AGM battery shot………….. After a LOT of deliberation I decided to go with Victron and chose their “Super Cycle” AGM batteries. 
PXL_20230426_213319964We chose Victron equipment for the entire electrical system on Möbius including their Isolation Transformer, MultiPlus Inverter/Chargers, MPPT controllers, Octo and Cerbo GX monitoring, etc. so they are a company that we have come to know well and not doubt have a bias for and I’m sure this did influence my final choice and Victron offered multiple batteries in both LiFePO4 and AGM to chose from.
These Victron SC AGM battery model are 12V @ 230Ah C20 and one of their more interesting qualities that caught my attention was their stated ability to withstand 300 complete 100% discharges without any damage to them although it certainly would shorten their lifespan if you were to do that.  Having gone with Victron for almost all of the equipment that makes up the overall electrical system on Möbius, I have come to trust and respect them as a company but I still wanted to verify these claims and was fortunate to find that Bruce Schwab at Ocean Planet Energy OPE, was able to personally verify Victron’s claims of these Super Cycle batteries based on OPE’s direct testing and he wrote:

Being a Victron distributor, we have tested the Victron Super Cycle AGM 125Ah (G31 size) in our PSOC regime. Nearly all Pb batteries suffer permanent capacity loss when run through this 30-cycle PSOC test.  We’re happy to say that the Super Cycle AGM passed with flying colors, with no discernable loss of capacity.


bruce-schwab-energy-systems-logo-SHORTI was therefore delighted to be able to work directly with Bruce and his tech Kevin at Ocean Planet Energy and can not recommend them more highly.  Bruce was incredibly responsive throughout the whole process, answering all my barrage of questions leading up to the choice of these Victron batteries and then getting the new batteries along with some additional Victron equipment ordered and delivered to the marina here in Norfolk VA. 

Bruce and Kevin worked with me very closely during the entire installation and configuration of the whole new electrical system to get it dialed in “just right”.  It is all too rare in my experience that you find such high degree of expertise along with truly exemplary service and so my hat off to Bruce and Kevin, can’t thank you both enough.  If any of you have any electrical needs for your boat I’m sure you will thank me later for contacting Bruce and his staff at OPE and similarly benefiting from their expertise and incredible customer service.

* NOTE:  Just to be clear and transparent, I am not sponsored by OPE or Victron or any other manufacturer, just a very satisfied customer wanting to share my first hand experiences with these high quality companies and people.

OUT WITH THE OLD;

XPM 6S4P House BatteryHere is the schematic showing how the original House Bank of 24 FireFly L15+ Carbon Foam batteries was setup.

     (click to enlarge this or any other photo)


PXL_20230727_154145252This is one of the three sealed battery compartments that are built into the hull with the batteries stradling the 1″ thick center keel bar so that all their weight acts as nicely centered “lead ballast”.  As per the schematic above, each of the four banks of FireFly batteries were wired directly to the positive and negative main bus bars inside the Grey DC Distribution box you see here.  All cables are of equal gauge and length, hence the looped Red & Black cables,   Positive cables from each bank have their own Off/On Battery Switch (Grey switches top left corner) and the negative cables each connect to the Neg bus bar through their own shunt for the Victron BMV712 battery monitors.  Fortunately I was able to reuse all these cables and battery monitors for the new batteries.
PXL_20230727_154208403This is the forwardmost battery compartment with the lid removed to start disconnecting all the batteries.
PXL_20230727_162322153With all the interconnecting battery cables and copper bars removed these 8 batteries are ready to leave the building.
IMG_3076Each FireFly battery weighs 43Kg/94lbs but fortunately they had very good handles on both sides so lifting them up and out went well.  This is the first eight of 24 batteries out on the dock beside the boat.

OUT OUT OUT with the OLD!

PXL_20230821_150439744A bit of a sad end to what should have been a much happier relationship with these FireFly batteries, but it is what it is.
PXL_20230821_145518401Enlisting the generously offered assistance of the marina staff and their golf cart to make the looooooooong trek along the maze of docks to get from the boat to the shore, we were able to transfer the batteries from boat to shore to pickup truck to take them to the battery salvage yard.

A forklift sure makes life easier once I got the batteries to the salvage yard!
PXL_20230821_150422017At least I was able to offset the cost of the new batteries with the money for the 2317 lbs of lead contained within the 24 FF batteries. (less weight of case, gel, etc.)

Bye bye FireFly; Hello Victron!

IN with the NEW

PXL_20230809_174034822The new batteries were delivered a few days later and with some help from the marina staff and their golf cart, we were able to bring the new batteries out to the dock beside Möbius.
IMG_3077.With the old FF batteries removed I could take out the fiberglass pans and modify them to fit the new batteries.  Not actually required by ABYC for these sealed batteries but a smart “belt & suspender” safety feature I think. 
PXL_20230802_200212279Each of the three pans needed to be extended in length so I just cut them in half with my circular saw ……….
PXL_20230807_154258855and then glassed in the space between with new cloth and resin.


Just visible on the far left end of this pan you can see the new SS tie down D rings I installed for the ratchet webbing used to secure the batteries in place.

Now all that was needed was to lift each of the 125lb new batteries from the dock down into the Basement and then lower them into their new home inside each battery compartment.

IN WITH THE NEW:

New Victron House Bank schematicThis schematic illustration will show you how the new House Bank is wired up.  Over the many years of boat ownership I have come to appreciate how important it is to keep ALL batteries very well balanced as they are being charged and discharged. 

    
NOTE: this is a schematic diagram only, cable sizes and lengths not shown to scale


This boils down to ensuring that each battery has the exact same resistance as their electrons flow in and out which is mostly determined by having the exact same size and length of cable connecting them to each other in the parallel and series arrangement required for such a multi battery bank setup.  It is similarly important that each individual battery bank also has the exact same cable gauge and length for their connections to the main positive and negative bus bars.

Also worth noting that all battery cables are oversized to 120mm2 (two sizes larger than AWG 4/0) to have less than 1% voltage drop.

Nigel Calder Boatowners Mechanical and Electrical Manaul coverI have also come to appreciate how much it helps to go the “extra mile” with the interconnecting cables to make all the series and parallel connections between each of the four batteries that make up each bank.  I first learned this method many years ago from Nigel Calder’s invaluable “Boatowners Mechanical & Electrical Manual” which you can see in Fig 1.21 page 22 if interested.

This is the wiring I used for each of the four batteries in each battery bank.

PXL_20230817_165919952You can see this in the schematic above and here in the actual cables installed on the new Victron SC AGM batteries. 

Small gauge wires you see here are for the various temperature and voltage sensors for monitoring these batteries with both Victron and Maretron.
PXL_20230815_140431433Christine’s son Tim flew up for a visit during all of this and being a very good certified electrician he generously worked with me for the whole installation process.  Here seen crimping the lugs onto the new interconnecting cables that needed to be made up.
PXL_20230817_165943879Tim does very high quality work which I certainly value highly and is also great to see in this new generation of electricians and workforce.  Good example here of affixing the SS ratchets and straps to this battery bank.
PXL_20230816_220800754Tim also took on the finicky mounting and then wiring of the three Victron Battery Balancers that we added to the installation. 

Thanks Tim, couldn’t have done it without you!!
Victron Battery Balancer connection diagramFor those interested, these battery balancers work as follows:

The Battery Balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 1A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge.

With the kind of $$ we boat owners invest in our battery banks, every bit that we can extend their lifespan helps and is well worth doing in my experience.

It took a few days working with Bruce and Kevin at OPE to get all the settings setup just right in the MPPT controllers, WakeSpeed regulators, MultiPlus chargers and BMV sensors and they went the extra mile and then some to help configure and finish up the installation.  We have been running the new Victron House Battery setup for about three weeks now and it is performing flawlessly.   I’ve tested it both with and without shore power and the each battery and each battery bank has stayed perfectly balanced and performing just as hoped. 

A very good feeling after nursing the original House Battery along for the past year but we now have a great setup that should continue to meet all the significant electrical demands aboard Möbius.  This is very much a “battery based” boat with all DC and AC power coming from these batteries so this really adds to the SWAN or Sleep Well At Night factor on our beloved Möbius.

Congratulations if you’ve made it this far in this all too typical “brevity challenged” update.  With any luck there won’t be any more big jobs like this to report on but I will post updates from time to time as things evolve aboard and soon hopefully off of the Good Ship Möbius.
