Compatible Motors

The supplier lists compatibility with selected motor models, including:

• Bafang BBS01B, BBS02B, and BBSHD

• Tongsheng TSDZ2B, TSDZ8, and TSDZ16

• Selected Varstrom motors

• Other listed motor models, subject to exact configuration

How to Choose Your Battery

Choose the Correct Voltage

A 48V battery and a 52V battery are not automatically interchangeable. Confirm the battery voltage supported by your motor controller and charging system.

Choose Your Capacity

A larger Ah rating generally provides more stored energy at the same nominal voltage. Actual riding range depends on terrain, rider weight, assist level, motor power, temperature, and riding conditions.

Check the Battery Case

Hailong, Hailong MAX, Bafang CAN, and Yingwu housings can differ in shape, dimensions, rail, and connector. Confirm the case matches your bike frame and mounting hardware.

Match the Charger

Use only a charger intended for the selected battery voltage and chemistry. Charger amperage affects charging time, but the battery's approved charging current must not be exceeded.

Frequently Asked Questions

The supplier lists the BBSHD as a compatible motor. Confirm voltage, discharge-current requirements, connector, and physical mounting compatibility before ordering.

Can I use a 52V battery on a 48V motor?

Only if the controller and complete electrical system explicitly support the battery's voltage range. Check the controller's maximum battery voltage before choosing a 52V pack.
