Derby e-bike battery regeneration – restore the full power of your ride

Regeneration Derby is a professional service that restores your e-bike battery to near-original performance. Over time, every battery loses efficiency – range decreases, voltage drops under load, and recharging becomes more frequent. By replacing worn-out cells with brand-name components such as Samsung, Sanyo or Panasonic, your Derby battery regains its reliability, capacity and power. This solution is cheaper, faster and more environmentally friendly than purchasing a new battery.

Why choose regeneration?

Buying a new Derby battery can be very expensive. Regeneration offers similar results at a fraction of the cost. We reuse the original housing and BMS electronics, replacing only the full cell block. This ensures full compatibility with your bike while avoiding unnecessary electronic waste. It’s the smart choice for riders who want to save money and protect the environment without compromising on performance.

How does the process work?

The service begins with a full diagnostic: capacity measurement, voltage testing and inspection of the electronics. We then open the casing, remove the old cells and check the BMS, resistors and thermistors. If any components are faulty, they are repaired or replaced. Next, we install new branded cells, which are joined using professional spot welders to guarantee strength, safety and long-term durability.

Testing and quality control

Every Derby battery goes through rigorous testing after assembly: complete charge and discharge cycles, capacity checks, load tests and BMS calibration. Only batteries that pass all stages are returned to customers. On request, we also test your old charger or battery free of charge to rule out additional issues.
