Hey all, long time lurker first time poster.
I got my hands on a used Bluetti that has a BMS defect i believe. The device will not take a charge via the Inputs (tried both). (error 43 Low BMS voltage)
My plan is to totally disassemble it and but the battery on a bench supply to charge it. (After checking cell voltages)
I don't want to deconstruct the entire battery pack, so my question is
1. Do you foresee any issues with charging the battery in series with 48V on a bench supply? Was thinking slow and long, 2-3 amps
2. If the load portion is disconnected should i still disconnect all BMS components from the battery just in case?
Thanks for any feedback!
