Panterra Battery Refurbishment – restore the full power of your e-bike
Panterra e-bikes are appreciated for their balance of affordability and reliable performance. Their batteries deliver solid range, but like all lithium-ion packs, they gradually lose capacity over time. Reduced mileage, longer charging times, or sudden power drops are clear signs of aging. Instead of investing in an expensive replacement, Panterra battery refurbishment offers a smart, eco-friendly solution to bring your e-bike back to life.
Why do Panterra batteries lose capacity?
Every battery is designed for a limited number of charge and discharge cycles. Daily usage, temperature variations, and improper charging habits accelerate wear. Panterra refurbishment involves replacing worn-out cells with premium new ones from Samsung, Panasonic, or Sanyo, and carefully checking the protective electronics. This restores the battery’s original capacity and ensures safe, stable performance.
The refurbishment process
Each Panterra battery undergoes a detailed refurbishment procedure in our workshop:
- Diagnostics: voltage testing, BMS inspection, and load analysis.
- Disassembly: opening the case, removing old cells, and inspecting electronics.
- Cell replacement: installation of new branded cell packs (Samsung, Panasonic, Sanyo).
- Safety check: verification of sensors, resistors, and protection circuits.
- Final testing: complete charge and discharge cycles under realistic conditions.
After refurbishment, the battery is sealed, labeled, and shipped back to the customer with a 12–24 month warranty.
Benefits of Panterra battery refurbishment
- Much cheaper than buying a new battery.
- Eco-friendly – less electronic waste.
- Only high-quality brand cells used.
- Restored range and consistent performance.
- 12–24 month warranty on refurbishment.
- Fast turnaround – most jobs completed within a few days.
Panterra – e-bikes for everyday riders
Panterra has built a reputation for delivering practical e-bikes at an affordable price point. Their batteries power thousands of bikes, offering reliable energy for commuting and leisure. With Panterra battery refurbishment, you can extend the life of your e-bike without overspending on a brand-new pack.
Why choose us?
With over 14 years of experience and thousands of successful projects, we specialize in bringing batteries back to life. We use only new branded cells, advanced diagnostic equipment, and provide full written warranties. Each refurbished Panterra battery is returned fully tested and ready for long-term use.
A second life for your e-bike
