I use the Bluetooth for soc. In reality I almost never check it. I only look to see how the batteries cells are balanced every once and a while. Most of the time it is connected to the system and is ready to go farther than you are.

I use the bms for state of charge. I have a dc to dc converter for the 12v components and no fuses or breaker because I'm an idiot who somehow never thought about this until now.

Really nice build. I watched and liked your video, it is much more entertaining than mine.

I don't know if it would qualify since it is removable.

Don't know if this will help but here's what I built. https://diysolarforum.com/threads/diy-230ah-eve-mobile-battery-aka-ezgo-golf-cart.40927/

I have 230 ah cells with a 300 amp bms . It has a top speed of 35mph and has about 100 miles of range if you drive with efficiency in mind. My cart pulls 200+ amps at a full throttle standing start. When it is connected to my solar it is doing very light duty in comparison. Here's the video I...

I bring cabinets like these to the scrap yard on a regular basis. The are so large no one seems to want them in my area.

It's a old control cabinet I got from a job. I rebiuld controls for machines. Here's some pictures of my biuld. https://diysolarforum.com/threads/4-mpp-lv6548-30-kw-eve-304ah-lifepo4-battery-14-kw-pv-array.32343/post-449279

Thread 'DIY 230Ah EVE Mobile Battery (aka) EZGO Golf Cart' https://diysolarforum.com/threads/diy-230ah-eve-mobile-battery-aka-ezgo-golf-cart.40927/ This is what I built. I have it installed so it can run as part of my system.

Thanks for the compliment. I put the batteries in the 1/8 steel enclosure for fire safety. I never worried it might contain the off gas too well and cause another problem.

You normally want it as close as possible to the meter to have the shortest amount of parallel paths it can return to the transformer on.

Thread '4 MPP LV6548 / 30 kW EVE 304ah LiFePO4 battery/ 14 kW PV array' https://diysolarforum.com/threads/4-mpp-lv6548-30-kw-eve-304ah-lifepo4-battery-14-kw-pv-array.32343/ This is a very similar system. Hope you can see something that will help.

I used a 1/8 steel control cabinet to store my cells. I don't think there is a tremendous risk of fire, but it doesn't hurt to over build if practical.
