Remark
：
Charge and discharge overcurrent protection: After charging protection, it cannot be charged but can be
discharged; after discharge protection, it cannot be discharged but can be charged.
Solution
Check whether the communication line is plugged in
tightly, the connection is reliable, and restart after
troubleshooting.
Stop charging and check whether the charging
voltage is too high.
Stop charging immediately and check whether the
charging voltage is too high.
The battery is undervoltage, it is recommended to
charge it as soon as possible.
