What BMS did you end up getting? I'm considering a similar battery configuration.

0:52 until 1:30 ish, rest is him building it

My original assumption was to do this, but then watched Will's video stating that was not a good method for how to build the battery bank

You are correct, I am trying to make a 4P4S pack. I'm newer to the DIY battery systems and haven't really seen (still researching) many products for this type of application. I am limited to 12v due to the DC-DC charging as I don't have a ton of space for solar (maybe 600W max, but would need a...

Hello all, I need help. I am upgrading my vehicle system: From a 12v 100Ah AGM connected to a CTEK DS250sa (charged from alternator and 200W of solar) to DIY 12v 400Ah Lithium connected to a Renogy DCC50S DC-DC MPPT (charged from alternator and 400W of solar), a Progressive Dynamics 12V...
