Hi - So last spring I built 2 x 12V batteries each with 4s 280Ah lifepo cells and 120A overkill solar BMS. I top balanced the cells and hooked everything up and it seemed to work great. Then I installed the pack in my van and discharged to around 50% - since it was going to be a few months...

I read somewhere that these batteries should not regularly go below 20% SOC. I have overkill solar 120A BMS. I discharged for the first time after top balance and I saw 0% battery Indication on BMS app. So question is: - Do I need to set this? - Where do I set this? Similarly - looks like...

I'm interested in thoughts on hooking 2 LifePo 280Ah batteries (each with 120A overkill BMS) in parallel via SB175 anderson connectors to: 1. Positive side to 250A fuse 2. Negative side victron shunt Anderson connectors would allow easy removal of one or both batteries - if service was...

Just sharing my in process build here. I’m following the excellent top balancing instructions here. I put together the battery to do the initial charge. Then I will disassemble and re-assemble in parallel for the top balance charge with the power supply. I had a switch and fuse bus bar...

I think I know the answer here. But I’d like to confirm my understanding. My plan was to build two 12v 280Ah batteries for my van - each with 120A Overkill solar BMS or a 4S2P 12v battery bank. But I’m going middle-aged blind and I mistakenly ordered 1 set of 4 x 280Ah cells and then a few...
