A8： Charging it overnight will usually not damage the battery, provided you are using a suitably designed charger and the battery itself is in good condition. At the same time, our battery is installed with 12A BMS. BMS monitors the voltage of the battery, and once it detects that the voltage reaches the preset overcharge threshold, it will take measures to stop charging. This is usually accomplished by cutting off the charging current or sending a signal to the charger to stop charging. This prevents the battery from continuing to receive charging and causing the voltage to exceed the safe range, thereby avoiding overcharging. However, charging for a long time may increase the temperature of the battery, which may have a certain impact on the battery life. To maximize the life of your battery, it is recommended to follow the charging recommendations and to regularly check the status of your battery. If you are concerned about the safety or longevity of your battery, consider using a smart charger with an auto-stop function, as well as regular battery inspection and maintenance.
