And would potentially reduce the heat problem.

Made some progress on this little project tonight. Cells have been top balanced and the box is mostly built, just need to add some feet to the bottom and a cover on top. The base panel has a pass through for the wires coming off the cells that’ll run down to the BMS mounted on the underside.

What a cool project! Can’t wait to see how it turns out. Will that box fit in the stock cargo tray? Also, since the batteries linked are 3.2 V do you wire them in series to get to 12?Made some progress on this little project tonight.

Yes, I’ve designed it to fit in the stock tray. Correct, it’ll be a 12V battery with the 4 cells wired in series.

Feet attached. All that’s left is the lid and then I can wire everything together. Test fit was a success with plenty of room to spare.

Looks fantastic! Any consideration to rewiring the factory 12V plug beside it to tap in to that system?

Project complete!Everything fit great and no issues with the wiring. Now I just need to connect it to my DC-DC charger and add some outlets to plug things into it.
Came out great

Sub, love the box and the concept. Did you stick to the $600 budget?

I only spent $184 for the battery. The smart shunt was another $70. I already had the boards and wires leftover from other projects.

lol, there’s no way I’d want to produce this to sell with my tooling. The wiring and assembly was pretty easy, but the box construction takes a while using just a drill and saw. Using a 3D printer would make things much easier, but I don’t have one.

Version 1.1: Rerouted the positive wire over to connect to a sub-module I built with a fuse block mounted. This fills out the rest of the space in that tray nicely and allows the safe connection of several terminals.
