Battery Compatibility
This service is intended for the battery model shown on this page. If you are unsure whether your battery matches, send photos of your battery, charger, and bike to EMP for verification before ordering.
Compatibility is confirmed using battery labels, case style, voltage, and connector information.
Warranty coverage varies by battery type, service performed, and battery condition. Warranty details will be provided with your final rebuild quote and service documentation.
In addition to battery rebuilds, EMP may be able to repair:
• Battery Management Systems (BMS)
• Charging ports
• Discharge connectors
• Internal wiring and fuses
• Battery rails and mounting systems
• Battery cases and lock assemblies
Repair options depend on battery condition and parts availability.
Some battery housings can support higher-capacity cell configurations than originally installed. When possible, EMP can increase battery capacity to provide longer riding range and improved performance. Upgrade availability varies by battery model and internal space.
Do I need to send my battery?
Yes. Most rebuild services require your original battery.
Can my battery be upgraded?
Many batteries qualify for capacity upgrades.
What if my battery cannot be rebuilt?
EMP will discuss available repair or replacement options.
How long does service take?
Most rebuilds are completed within 10–14 business days after intake.
Please send clear photos of your battery, charger, and bike before shipping whenever possible. Do not ship batteries that are swollen, leaking, smoking, or physically damaged without contacting EMP first.
