My battery bank have (4) 24v 100Ah batteries connected in 2P2S to give me 48V 200Ah. The manufacturer recommend i disassemble the pack and do a balancing every 6months.
Suppose I decide to get (2) 24V Lifepo4 charger and connect them.to each side of the series connection do u think it would charge each of them to 28.8v so that all batteries would be reading the same voltage whilst still connected in the parallel-series connection? This charging would take place once every couple months just to bring the SOC and voltage reading close as possible and i think i would let this occurs only when the outback mppt has reach 54.6v or near a full charge so basically when the charge controller reaches 54.6v and begins to float charge then the 2 chargers would commence charging of each side of the battery pack of so that there won't be any voltage difference between them or the most would be 0.01v at the end of the charge cycle. I would only do this when i notice a voltage difference between the 2 sides later on in the future as i don't expect to see it anytime soon because i have been using the batteries over 3 months now and the 2 sides are still showing the same voltage reading.
I would go with either a 1 or 2 Amp 28.8v Lifepo4 charger
Can this method work?
