ES: Simultaneously breaking down two older LiFEPO4 plug-in-hybrid packs from higher voltage to nominal 48V's 16s configurations. I need some Endless-Sphere help in reconciling why the same charger>BMS will have different end voltages? The A123's ends at 59.4 volts and balances the cells nicely. The Headway 40152 SE cells end at 57.0 volts and thus doesn't balance the cells. There are no circuits other than the Ping 5 amp charger and generic BMS. Can anyone suggest a reason why the Headway's stop at the lower voltage? Supposed to be 3.65 charging voltage, for 16s that is 58.4 volts. Again, all cells are old, temperatures are the same. Thanks in advance for any perspectives.
