Our Expert Battery & BMS Repair Process
When your faulty battery and BMS arrive at UpFix, our techs begin a full inspection and load test. We identify failed components, balance cells, upgrade known weak points, and update firmware when needed. The repaired unit is then tested under real-world conditions to ensure reliable performance and safety.
A “no-charge” symptom often stems from BMS lock-out, cell imbalance, or a broken charge port. We rebalance cells, update your BMS firmware, and repair any wiring faults to bring charging back online.

Absolutely. We flash your BMS with the newest firmware release to optimize cell balancing, thermal management, and safety protocols.
A 0 V reading means the BMS has likely shut down or there’s an open connection. We pinpoint whether it’s the BMS electronics or a cell fault and perform the necessary repair.

A full diagnostic check should first be performed to eliminate all other possible causes for your symptoms, even if the symptoms match those specified on the common fault description.
If you send a unit in good working condition due to misdiagnosis, and our testing determines that there are no issues or faults with the unit, or if the part is beyond repair, then you will only be responsible for the shipping costs and a bench test fee of $69.99 may be applied.
IMPORTANT! If you are not sure that this part is the cause of the fault then we recommend that you do not go ahead with this purchase and instead seek further professional advice and diagnosis.See Why Our Customers Love UpFix!
