Nice thanks for sharing the photo, gives perspective how small those factory cubbies are! I'm still planning to remove the behind seat cubbies and build my own back wall rack to hard mount everything. Changed my thinking now and probably will go Victron instead of Redarc. I have too many...

I badly want (need) a slim-type form factor battery for mounting behind the rear seat in my offroad truck. Most pre-built options on the market are questionable, and almost all are from Australia which poses shipping headaches due to the LFP. Is anyone aware of an off-the-shelf empty battery...

Thanks for checking. Since I'm only doing a single 12V 100ah the LCD screen isn't a feature I need or want. But I do need the Bluetooth (either built-in or via the Victron BMS) to mitigate having no screen. Also I just saw on the Signature Solar site they have some form of a teardown video. Not...

D'oh good catch! Serves me right for making wiring diagrams late at night! I'll correct my drawing later but for now it's off to bed.

This might be a really dumb question, but can I run the GND cable from the Orion-Tr to the negative bus bar, then run a cable from negative bus to chassis ground? As opposed to my drawing where I’m running two separate cables (and ultimately using the same chassis bolt for both anyways)? Again...

Bump and price drop to $180. Get some DC-DC in 2023.

Well it's hard to go to bed when you are making progress....but I'm happy I have the main structure ironed out so I can order the bulk of supplies tomorrow. Drawing v0.3 completed. Lesson learned tonight: Visio kinda sucks.

Wow thanks for all the great info. Will try to answer why I planned the things I did: I am still 100% considering that route. That was my first thought after watching Will's videos, Like you said I would know "what I have" and I live by that motto for other parts of my life like vehicle...

Bump and price drop to $150. Feels like I'm getting close to giving it away.

Just took another look at their website, seems like they are updating. However it does show the new product with Bluetooth and heater being restocked on March 10th. Price of $650 with free shipping. Unless someone tells me the app is hot garbage compared to the Overkill/JBD then I'll probably...

I considered using extrusions but I think for my application they are just too big and chunky. After looking at some other designs, I'm starting to formulate some plans for a DIY frame that should be easy to build if I can't find something off-the-shelf. I also currently own an SOK 206Ah marine...

Most definitely and great points, I will be testing angles/orientations more once I finish the build.

Went back and tried to get even more specific without going too nuts. Yes you are correct, there are inline fuses on the sense wires supplied with the Smart Shunt; I have added them in the image, and I should note the Aux wire to starter battery probably will get left off for now (I have...

Bump.

Awesome thanks! And yeah there’s always room for revisions. I already see so many things wrong with my plan due to space constraints but it’s going in anyways because papa needs cold beer on the road trip. Next revision will be a massive improvement because I’m basically a caveman rubbing sticks...

Due to time constraints I ended up with an SOK 206Ah marine battery for now. Still interested if anyone knows of a "slimline" battery that is already built, or an empty case/shell to build my own without having to make an entire chassis. If not I'll just make one but it will take much longer...

Bump and price drop to $190. Happy holidays.

Wanted to come back and say thanks again to everyone who helped me out. Might do a write-up later if I get time. Anyways, here's a photo of the first revision - lots of last-minute design changes on my rear seat delete platform due to the size/dimensions not being what I thought, but...

Bump and price drop to $170.

Hello, I'm still a newbie and drinking from the firehose. I'm also now on a timecrunch for the start of my project and since I can no longer procrastinate it's time to dive in head first. General idea is a 12v LFP house battery inside the truck cab + Victron Orion-Tr to charge at 30A + Victron...

SOLD, thank you!

Hello, I've been trying to plan a small 12V system for use in my truck when off the grid. Found this place thanks to Will's great videos which have now sent me down the rabbit hole of building my first setup. Looking for some feedback/critique from DIY Solar on my plans to help find issues. My...

Apologies in advance if I missed something - I swear I have searched quite extensively and didn't find what I'm looking for. Is anyone aware of a reputable "slimline" battery with capacity of at least 200Ah that can be purchased from a good US-based supplier? Absolutely must have low...

Interesting thanks, I'll put that on my list of things to research. Price is better than the Redarc and of course more output but physical size is larger. I'll have to get more precise measurements of my seat area soon (waiting for weather to warm up, it's freezing right now).

I've seen EG4 mentioned several times but more for the rack battery that Will tested. Haven't seen a teardown on that 100ah version though, does something like that exist so I can see the insides? Screenshots for that bluetooth app don't look very robust but I can't find any more about that...

Awesome thanks Todd, that's way more effort than I expected but great to see those 230Ah would fit! Lots of room for the smaller 100Ah I'm planning to go with. You are correct there isn't much height to gain by removing bins, however there is unusable space on top & sides from all that plastic...

I put the image of the circuit breaker there mostly to remind myself to install some type of switch/cutoff. Likely I used that image because it was the first thing I put into MS Visio, not neccesarily because it's the best or correct item for the job. Good to point out that a switch would be...

Looks like you changed your mind? If not, yes it is still available, send a message if interested. Happy New Year!

Thanks for the tip, I couldn't figure out how to re-orient the text in Visio and felt like I was going crazy. I'll change that on the next drawing rev for better readability. And yes definitely having good documentation is invaluable, I couldn't agree more! Parts are starting to arrive daily...

Selling a very gently used Victron Orion DC-DC charger. Used for about 3 weeks on a road trip and it works perfectly, I'm just going in a different direction for my house power setup. The only flaw is a small amount of chipping on the heatsink where the mounting bolts scraped away the black...
