FAQ​

 

Q1.What is a Hailong style e-bike battery?

A. A Hailong style battery is a widely used external e-bike battery pack named after the popular Hailong case design. It is typically mounted on the downtube and known for its compact size, sturdy ABS+PC casing, and easy installation.

Q2.. Is this battery compatible with my e-bike?

A.Compatibility depends on three key factors:

Voltage​ (e.g., 36V ) must match your controller and motor.

Physical size & mounting​ must fit your frame (Hailong style uses standard brackets).

Discharge connectors are selected and configured to match your system requirements. Share your mating connector interface or wiring drawing, and we will confirm a compatible solution before production.

Please check your original battery specs or contact us with photos before ordering.

Q3.How do I dispose of the battery at the end of its life?

Yes, as long as the voltage remains the same, you can upgrade from (for example) 10Ah to 15Ah or 20Ah to extend your range. A higher capacity battery will be slightly heavier but offers longer riding distance per charge.
