I made a ebike a year ago and i changed hub motor because i broke aluminum disk in previous one and changed 3 controllers. I used a 36v battery max voltage 42v after 2 months i become greedy and added another 1s in 10s battery with other bms now i was using two batteries with 2 bms with 2 different chargers 1 battery was a 42v battery other was 4.2 v so in total i get 46.2-46.5 v .Now the problem is when my ebike was 3 months old my battery autocut itself at near 36-37v after 3 months it started autocut at 33v
But now it even touched 31v .what's the matter with my ebike battery bms??? Rest of the function are normal.
