Regeneration Xiaomi – restore your e-bike’s power and range
Xiaomi electric bikes are admired for their modern design, affordability, and smart features. The batteries that power these e-bikes deliver impressive range and smooth assistance when new, but like all lithium-ion packs, they inevitably wear down over time. Reduced capacity, longer charging times, and sudden drops in power are common signs of cell degradation. Instead of paying for an expensive replacement, Regeneration Xiaomi offers an economical, ecological, and reliable way to give your existing battery a second life.
Why Xiaomi batteries lose capacity
Lithium-ion batteries do not fail overnight. Each pack is designed for a certain number of charge and discharge cycles. With daily commutes, weekend rides, and seasonal use, those cycles add up. Heat exposure in summer, cold winter storage, or keeping the battery uncharged for months accelerates wear. Eventually, you may notice your bike covering only half the distance it once did or shutting down when climbing a hill. These symptoms indicate that the cells are depleted, but the case, electronics, and connectors remain functional. That is when Regeneration Xiaomi becomes the smart solution.
The detailed regeneration process
Every Xiaomi pack that reaches our workshop goes through a multi-step renewal process:
- Comprehensive diagnostics: voltage balance checks, BMS scan, and stress testing under load.
- Safe disassembly: careful opening of the housing and inspection of all protective circuits.
- Cell replacement: installation of fresh, branded cells exclusively from Sanyo, Samsung, or Panasonic.
- Electronics inspection: resistors, thermistors, and sensors are tested and replaced if needed.
- Reassembly and sealing: precise spot welding, resealing of the pack, and application of protective insulation.
- Final validation: multiple full charge and discharge cycles to confirm capacity, stability, and safety.
Only after a pack passes every step do we return it, security-marked, and covered by a warranty lasting from 12 up to 24 months.
Benefits of regeneration vs. replacement
- Cost savings: a rebuild costs significantly less than purchasing a new OEM battery.
- Ecological choice: reusing the case and electronics prevents unnecessary electronic waste.
- Premium quality: only top-tier branded cells ensure consistent range and reliable performance.
- Fast turnaround: most services are completed within just a few working days.
- Guaranteed reliability: every rebuild comes with a written 12–24 month warranty.
Experience and trust
We have been specializing in battery regeneration for over 14 years, completing thousands of successful projects for riders across the country. Our team uses precision tools and modern diagnostic equipment to ensure each rebuilt pack performs like new. This long-standing expertise allows us to deliver consistent quality, whether your Xiaomi battery is used for daily commuting or long weekend tours.
Why choose regeneration for your Xiaomi e-bike
Buying a brand-new battery is not always the most rational choice. High costs, long delivery times, and unnecessary waste make it less attractive. With Regeneration Xiaomi, you extend the life of your existing pack, regain the original range, and reduce your environmental footprint. Many of our customers report that their rebuilt packs often outperform the original in stability and endurance, thanks to the u
