- short connect P-and B- with black and red probe of multi meter. Zero=Bms is fine. nothing wrong.
Why do BMS fail?
The voltage detection wire has failed due to poor connection, crimping process, or poor contact. The BMS has no voltage information and should not stop when charging stops. In addition, overcharging can easily cause the electrolyte in lithium-ion batteries to decompose and release gas.
