Initial Setup and Installation

Before installing the battery, ensure it is compatible with your e-bike frame and motor. Check the dimensions provided in the specifications section.

Battery Connection

1. Check the new battery's positive (+) and negative (-) positions to ensure they match your old battery or e-bike system.
2. Connect battery wires separately and ensure they are separately insulated to prevent short circuits.
3. Make sure the two wires of the battery are well insulated.
4. Turn on the battery or your e-bike system to test the connection.
5. If you need to disconnect the battery wires from your e-bike, do so separately and ensure each wire is separately insulated.

Operation and Charging

Charging the Battery

1. Upon receiving the battery, it needs to be charged before its first use, as it is shipped at a low voltage for safety.
2. First, plug the charger's AC plug (wall plug end) into a power outlet.
3. Then, connect the charger connector to the battery's charge port.
4. The charger's LED light will turn red, indicating that the battery is charging.
5. Once the battery is fully charged, the charger's LED indicator will turn green.
6. After the charger turns green, disconnect it. First, remove the charger's AC plug from the wall outlet, then disconnect the charger connector from the battery.
7. If the battery is not used immediately after receipt, please charge it for approximately 2 hours before storing. When you decide to use it, charge it fully before operation.
8. The battery should be charged at temperatures between 0°C and 45°C. Charging below 0°C is not recommended.
9. Some 4A or larger chargers may require adjustment to 110V or 220V depending on your local power supply.

Optional External Discharger Plugs

The battery supports various external discharger plug types. If no specific request is made, the Anderson-2 connector is typically sent as the default.

AC Power Cable Plugs

The charger will be provided with a standard plug suitable for your country/region. Available plugs include EU, US, AU, UK, and Japan types.

Maintenance and Storage

• Keep the battery dry, clean, and tidy when using and storing. Moisture and stains can cause aging, oxidation, and short circuits of internal components.
• It is recommended to charge the battery before it gets too low. Prolonged use at low power can cause excessive discharge. Recharge the battery before it drops below 25% to prolong its cycle life.
• The optimal operating temperature for the battery is between -20°C and 60°C.
• For storage, the recommended temperature ranges are:
  • 1 year: -20°C to 25°C
  • 3 months: -20°C to 45°C
  • 1 month: -20°C to 60°C
• When transporting the battery, keep it at low power, preferably 30% or less, for safety.

Troubleshooting & FAQ

Q: How to choose a replacement battery?

A: Firstly, ensure the new battery pack size is suitable for your e-bike.

Thirdly, if the battery box size allows, you can choose a higher capacity (e.g., 12Ah or 14Ah instead of 10.4Ah) for a longer range.

Q: Which kind of cells are built in the battery pack?

A: Most of our battery packs are made up of authentic Grade A 18650 battery cells from Korea or Japan, including Samsung, Panasonic, or LG brands. Some may use our own brand cells. Specific cell information can be found in the product description.

Q: What is a BMS?

A: BMS stands for Battery Management System. It is the circuit board that protects your battery pack and ensures its safe operation.

Q: Is customized service available?

A: Yes, customized batteries can be made according to your request. Please provide information such as voltage, capacity, size, and motor power.
