ok so my bms has been acting up i just "installed" it on my battery and everything was fine and it balanced but the 2nd time charging it wouldn't power my ebike (voltage would drop a lot not sure on exact). and i tore the battery back open.
1st i reconnected the balance leads, no luck
2nd reconnected bms and it sort of worked but still wouldn't power my bike so i connected a watt meter and bam now it works so i will ride my bike till its close to 10% and charge again to see if its fine
any reason this happened? did i do something wrong? this is my 3rd BMS and if its bad I must have really bad luck at finding bms's
battery is 14s8p at 20ah samsung cells and bms is 14s rated at 45A.
