Charging a bank of Lifepo4 cells (24v, 8S) I started to see some runaway at around 3.5v/cell so I stopped charging. I am assuming that they are B rated cells. After disconnecting the charger (No BMS) all of the 8 cells dropped to 3.3 volts and have maintained there. These cells were originally bottom balanced by me when I got them. Could this be why they go back to 3.3v?
My BMS is coming Monday and I want to top balance these cells now. Am I wasting my time? I wanted to get them to around 3.6, connect them in parallel and use a bench power supply to get them top balanced to 3.65 as per Will's directions.
Maybe this is not possible? Any help is much appreciated!
Thanks,
Dan
