Using your new e - bike battery is easy. First, use the included mounting bracket to attach the battery to your e - bike. Make sure it fits well with the compatible brackets as mentioned in the specifications. Connect the discharge connector (Micro Anderson) to your e - bike's motor. When it's time to charge, use the 3A ST charger that comes with the battery and plug it into the ST3 3 - pin charging port. Here are some important notes. Don't overcharge the battery. The maximum charge input is 5A, so don't use a charger with a higher current. Keep the battery in a dry and cool place. Avoid exposing it to extreme temperatures. For maintenance, check the battery power indicator regularly. If the battery seems to be losing power quickly or has any other issues, check the BMS protection. The 2 keys provided can be used for any locking mechanisms on the battery case. You can also remove the branding if you want a more customized look. And remember, this battery is certified, so it meets high safety standards.
