E‑Bike & Lithium Battery Repair in Tamworth (6V–100V)
Specialising in e-bike, e-scooter, power bank and custom lithium pack diagnostics, rebuilds and BMS-level repairs. If your pack won’t charge, cuts out under load, or has imbalance issues — I can diagnose and repair it.
Note: I may refuse severely damaged packs (e.g., fire damage or swollen/leaking cells) for safety and reliability.

FAQ
Disclaimer: Repairs involve used equipment and varying pack history. I test and verify, but no repair can guarantee original manufacturer performance.
