I am building two separate 12V batteries from eight 280Ahr prismatic cells, but I plan to connect them in series to create one 24V battery. I’m not connecting all eight cells in series directly because I would like to keep the weight down, taking them in and out of my boat As 12V batteries.
Question: do I use a single 8S BMS, or two 4S BMS units?
