BMW Lithium-ion starter battery repair M5 M8

Repair service for a non-functional lithium battery found in the M5 and M8. Those batteries are made by lithium energy japan and unfortunately no replacement model exist as there is an expensive computer inside the battery that is designed exclusively to talk to the DME in the M3. Replacing those battery from BMW is extremely expensive due to the high technological level.

We can make the battery accept a charge again after it has been over-drained or disabled after the car has had an airbag deployment. The cells are fully balanced and tested, then the battery is discharged to a safe level for transport and storage.

The battery must be sent-in and will be returned by ground shipping only due to regulations.
For safety reasons battery that have been previously opened are NOT accepted.
