My goal is to top balance qty 16 304Ah CATL prismatic cells that are currently all sitting at 2.90v except 1 cell that measures 2.88v.
My question is how to achieve this efficiently?
The 16 cells will eventually be wired in groups of 4 series connected cells and each of the 4 "12v" packs with it's own JK balancing BMS
The resulting "12v" packs will be connected in parallel, and feed a VIctron Multiplus II, 3kw inverter.
Is it best to top balance all 16 cells at once in parallel with a 3.6v high current lab / bench power supply? This will require many days / weeks /months
Or, can I wire my 12v packs (4s), connect each pack to BMS, then connect the 12v packs in parallel to the Victron Multiplus. and charge at 12volts, letting the BMS do the balancing?
