I have a Ping lifepo4 48v 20ah battery in need of an evaluation/repair. At the least I need assistance with replacing the bms and using my single cell charger to try and bring the cells into balance. I might possibly need to replace some cells if I'm not able to bring the individual cells up to voltage. I have the new bms and single cell charger on hand. I realize I only need to solder on the new bms but don't have any experience and don't want to risk ruining my battery.
Thanks in advance,
