@burny was kam denn eigentlich bei dir raus bzw wie ging es weiter?

@tribesman I’m using a physical trick here to protect the cells, even without an active balancer:
The flat LiFePO4 voltage curve: A LiFePO4 cell is already about 95% to 97% full at a voltage of 3.43 volts.
The safety margin at 110 volts: If I set the lab power supply exactly to 110.0 volts, these 110 V are distributed on average to 3.43 volts per cell (110 V / 32 cells). As I understand it, this would provide self-protection against overcharging. Even if the cells are extremely unevenly charged (“unbalanced”) and three or four cells are charging faster than the rest, the voltage range with a total cut-off of 110 V is so low that no single cell can ever reach the dangerous threshold of 3.65 V. The power supply stops the flow of energy well before the critical zone. Or am I missing something here?
