A Fresh Power Source for Your Folding E-Bike
Keep your compatible folding electric bike ready for everyday journeys with this 48V 7.5Ah lithium-ion replacement battery. With 360Wh of rated energy, it offers a replacement option when your existing battery has reached the end of its service life, or a spare once compatibility has been confirmed.
Designed for compatible 48V folding e-bike systems, this rechargeable pack combines lithium-ion energy storage with a built-in battery management system. Before ordering, compare your original battery with the product photos and check the electrical connection, casing and mounting arrangement.
Check compatibility before ordering: Matching voltage alone does not establish compatibility. The battery must also match your bike’s connector, polarity, controller requirements and physical battery compartment.
Why Choose This Replacement Battery?
48V Power for a Matching Electrical System
The 48V nominal voltage is intended for compatible 48V e-bike systems. Choose a replacement that matches the voltage specified by your bicycle manufacturer and the label on your original battery.
7.5Ah Capacity and 360Wh Rated Energy
The pack combines a 7.5Ah rated capacity with 360Wh of nominal energy storage. These specifications help you compare replacement options. Actual riding distance depends on your bicycle, riding mode, terrain, rider weight, temperature and battery condition.
Built-In Battery Management
The integrated BMS provides overcharge, over-discharge, overcurrent and short-circuit protection. These functions help manage battery operation during charging and use. Always pair the battery with compatible equipment and follow the supplied operating instructions.
A Replacement or a Compatible Spare
Replace an aging battery after confirming the cause of the fault, or keep a matching spare available for your bike. If your bicycle no longer charges or powers on, check the charger and electrical connections before assuming the battery needs replacing.

Check Your Battery Before Ordering
Folding e-bikes can use different battery systems even when they look similar. Compare the following details with your original battery:
- Voltage: Your bike must require a 48V battery.
- Housing and dimensions: The full casing must fit the battery compartment, including end caps and any projecting parts.
- Discharge connection: Match the connector shape, contact layout, polarity and position.
- Mounting and lock: Check the locating points, retaining mechanism and lock position.
- Charging connection: Confirm the charging port and the charger specifications required for this pack.
- Electrical requirements: The battery’s discharge capability must meet your controller’s requirements.
Need help checking fitment? Send Kornorge clear photos of your original battery label, complete casing, discharge connector, charging port and mounting or lock area, together with your bicycle’s exact model and battery measurements.
Getting Ready to Replace Your Battery
- Turn off your bicycle and disconnect the charger.
- Remove the original battery according to your bicycle’s instructions.
- Compare both batteries and confirm the casing, electrical connection and retaining mechanism match.
- Install the replacement using the bicycle manufacturer’s procedure and check that it is securely retained.
- Charge using a charger confirmed compatible with this battery, then check normal operation before riding.
If the battery does not fit or the connector does not match, stop installation and contact us. Do not force the battery into place or modify its wiring to make it fit.
Frequently Asked Questions
Does this fit every 48V folding electric bike?
No. Voltage is only one part of compatibility. The casing, connector, polarity, mounting arrangement and electrical requirements must also match.
Can I use it to upgrade a 36V bicycle?
This pack is offered as a replacement for compatible 48V systems. It is not a direct replacement for a 36V battery.
Will it make my bike faster?
A replacement battery with the correct voltage is intended to power your existing system. It does not change the bike’s programmed speed limit.
How far can I ride on one charge?
There is no single mileage figure that applies to every compatible bicycle. Riding range varies with the bike, assistance level, throttle use, route, load and conditions.
Is a charger included, and can I use my old one?
A charger is not included. Your existing charger should only be reused after its output specifications, plug and polarity have been confirmed compatible with this battery. A matching plug alone is insufficient.
How long does charging take?
Charging time depends on the compatible charger’s output and the battery’s starting charge level. Follow the instructions supplied for the battery and charger.
What information should I send for a compatibility check?
Send your bike model, the original battery’s measurements and clear photos of its label, casing, connectors, charging port and locking or mounting points.
