Bms is a battery management system. without bms for example: when charging some cell are over voltage and some cell not fully changed. when discharging then some cell are fully discharged and other cell are not fully discharged.

@cubityt
@cubityt 3 месяца назад
Check the battery voltage. If output voltage is less then 8.4v then might one cell damage. Then you need the removing all connection and check the 3 cell separately. Which battery cell voltage less than 2.4v you need to replace this battery another good one.. thank you

@@kennmossman8701 BMS is designed to cut off the charging voltage when the battery is full. This is an essential safety feature to prevent overcharging, which can damage the battery, create safety hazards, and reduce the battery's lifespan. The BMS monitors the voltage of the battery cells during charging, and when it detects that the cells have reached their maximum safe voltage level, it will disconnect the charging source to stop the charging process.
