Spark Prevention of Charging

Under specific conditions (overcurrent, short circuit,
overdischarge protection, etc.), the charger that needs
to detect the voltage of the charging port is not
supported. The pulse charger needs to be confirmed
before using, otherwise the battery protection cannot be
released.特定状态时（过流、短路、过放保护等），
不支持需检测充电口电压的充电器，脉冲充电器需
确认使用，否则可能会导致电池保护不能释放。
