2017 - 2020 Porsche Audi LiFePO4 12V Lithium Battery BMS Repair Service

## 2017–2020 Porsche • Lamborghini • Audi LiFePO4 12V Battery BMS Circuit Board Repair + Reset Service Professional BMS (Battery Management System) circuit board repair and reset service for Porsche, Lamborghini, Audi, and Bentley 12V LiFePO4 lithium batteries. Restore your original control board and avoid costly replacement. ## Same-Day Service • Free U.S. Return Shipping Ship us only your BMS circuit board (do not send the full battery). We repair the board, clear crash/locked data when applicable, and restore normal BMS operation. Your board is returned within 1 business day after we receive it. Free return shipping is included (inbound shipping is the buyer’s responsibility). ## How Our Service Works 1. 2. Remove and ship only the BMS circuit board from the battery (do not send the complete battery). 3. We bench-test, repair, reset, and restore the BMS logic. 4. We ship your restored board back within 1 business day after receipt. 5. Reinstall the board into your original battery. ## Common Symptoms - Battery locked after deep discharge (low-voltage protection / shutdown). - 12V battery warning / battery fault messages on the dashboard. - Stored crash/locked event data inside the BMS (post-accident). - DTCs related to BMS or energy management. - Battery shows abnormal behavior after storage or repeated discharge events. ## Important Information - This is a BMS circuit board repair/reset service only. No new board or battery is sold. - You must send only the BMS board (not the full battery). - Not covered: burned PCB, broken connectors, missing components, water/fire damage, severe corrosion. - All boards are bench-tested before return shipment. - If the battery cells are faulty, aged, damaged, degraded, or imbalanced, a BMS repair/reset will not restore battery operation. ## When This Service Is Not Enough This service restores the BMS electronics. If the board is repaired correctly but the vehicle still shows battery faults or continues to shut down, the cause is usually inside the battery cells, not the BMS board. In that situation, the complete battery must be serviced. A clear photo of the battery label is required before shipping.

The BMS can enter a protection state and isolate the battery from the vehicle power network. Our service restores normal BMS operation so the battery can communicate and function again (when the battery cells are healthy). ## Why Choose Our Service? - Save money vs. replacing the full battery. - Crash data reset and BMS reactivation included. - Fast 1 business day turnaround after receipt. - Free U.S. return shipping. We ship your repaired board within 1 business day after it arrives.
