This battery is available in multiple voltage and capacity options, making it suitable for a wide range of e-bike setups. Before ordering, we recommend checking your motor power, controller voltage, connector type, and available frame space to make sure the battery is compatible with your bike.If you're not sure which version is right for your setup, feel free to send us your motor and controller specs, and we’ll help you choose the best option.
The battery voltage must match your e-bike system and should not be mixed with a different voltage setup.In general:
For example, if your motor and controller are built for a 48V system, you should choose the 48V battery version. Choosing the wrong voltage may result in poor performance, system instability, or the battery not working properly.

To protect the battery and extend its lifespan, we recommend avoiding heavy rain, deep water, and direct pressure washing.
Actual range depends on several factors, including battery voltage and capacity, rider weight, road conditions, riding speed, temperature, and motor power.Depending on the battery version and the motor power it is paired with, the estimated riding range is typically around 30–70 km, with some higher-capacity versions reaching even more under the right conditions.For charging, this battery supports 5A fast charging, and most versions can be fully charged in about 4–5 hours.
