Hello all,
I have a prepackaged 12V 4cell 80ah lifepo4 battery if it has a BMS. I am trying to top balance the cells and I was wondering if it is possible to do so using the balance chargers without taking the battery apart to reconnect the cells in parallel. I am still unclear how the BMS is balancing them but I see it trying to when I use the supplied 10A 150W charger and it doesnt seem to be effective. Would perhaps using a lower power charger help out? Would buying a balance charger help?
I guess I am unsure whether the balance charger will do different since the BMS is in the middle regardless of which charger I use.
Would appreciate any advice, including any pointers to good reading material on how the BMS operates during charge cycle. I get that it activates resistors to try to match the cell loads but in that case, with a BMS it should be simple to balance the cells when charging and discharging.
