TranzX Battery Regeneration – extend the life of your e-bike power source
Your e-bike is only as reliable as its battery. When the power pack begins to fade, every ride becomes shorter and less enjoyable. Buying a brand-new battery is often an expensive decision, and in many cases, it is not necessary. TranzX battery regeneration offers a smarter alternative: restoring the original performance of your pack while keeping costs under control.
Why regeneration is a smart choice
Over time, lithium-ion cells naturally lose capacity. Instead of replacing the entire unit, regeneration allows us to install a fresh set of high-quality cells while reusing the existing housing and electronics. This process is not only budget-friendly but also sustainable, reducing electronic waste and giving your e-bike battery a second life.
The step-by-step process
Every TranzX battery that reaches our workshop goes through a detailed regeneration procedure. First, the battery is opened and carefully inspected. Old cells are removed, and the battery management system (BMS) is tested for faults. If necessary, protective components such as resistors, fuses, or thermistors are repaired or replaced. Once the electronics are confirmed to be safe, a brand-new set of premium cells from Samsung, Panasonic, or Sanyo is spot-welded into place using professional equipment.
After the rebuild, the pack is reassembled and tested under real-world conditions. This includes load testing, full charge/discharge cycles, and monitoring the balance of the cells. Only batteries that pass every stage are returned to customers, ready for many more kilometers of reliable riding.
Benefits of TranzX regeneration
- Cost efficiency: a fraction of the price of a new battery.
- Sustainability: less waste and a smaller environmental footprint.
- Performance: restored range and power, close to factory level.
- Safety: every unit is tested under strict conditions before shipping.
- Warranty: up to 24 months of coverage for peace of mind.
- Quick turnaround: most orders completed within just a few business days.
The TranzX legacy
For over two decades, TranzX has been developing innovative drive systems and batteries for e-bikes worldwide. Their components are known for reliability, user-friendly design, and long-lasting performance. By choosing regeneration, you continue to benefit from the brand’s technology while extending the life of your original system. There is no need to worry about compatibility issues or losing the authentic TranzX riding experience.

Bring back the freedom of riding

Don’t let a worn-out battery cut your journeys short. Give your TranzX power pack a second life and get back on the road with confidence.
