I'm "test" charging LiFePO4 battery modules, (4S24P), with a 12 volt lead acid, (car battery), charger. After a complete charge, the parallel groups are 3.4 to 3.9 volts. How can I limit each parallel group to 3.6 volts without a BMS? I'm fine with simply dissipating any excess voltage over 3.6 volts. I tried 3.6 volt zener diodes in series with a 10 ohm resistor, + to -, on a parallel group, but they are not dropping the higher parallel packs down.
This method worked on my 12 volt lead acid batteries to prevent over-charging.
I have built 26 of these 12.8 volt, 60 AH packs to replace the 26 lead acid batteries in my 1997 Chevy S10Electric truck. This is a factory built truck using the EV-1 drive train, (FWD), and charges with a paddle charger. There is a Battery Pack Control Module that monitors charging and I can't remove or bypass it. A BMS would conflict with this and I've never heard of a 104S24P BMS.
I'm sure there is a lot more I may need to explain.
Thanks
