Using your e - bike battery is easy. First, use the docking station to attach the battery to your bike's rear rack. The two keys provided are for safety and easy access. When it's time to charge, you can choose either the 2A or 3A charger and plug it into the ST3 charging port. Be aware that the cells in this battery are new and meet high - end standards, so avoid exposing the battery to extreme temperatures or rough handling. For maintenance, regularly check the discharge cable with the micro Anderson connector for any signs of wear. Also, keep an eye on the built - in tail light to ensure it's working properly. And remember, the Battery Management System is there to keep your battery in good shape, so you don't have to worry too much about over - discharging or over - charging.
