McLaren Battery Swap Kit / Battery Emulator

This kit provides the ideal solution for replacing your McLaren’s original lithium battery with an AGM (92Ah) or another non-OEM lithium battery — without triggering any system errors or low-voltage faults.

Important Notice:
Since the vehicle will no longer report low battery voltage, it’s essential to monitor your battery’s charge level regularly. Certain safety functions that depend on low-voltage detection (for example, the automatic slight lowering of windows) will no longer operate. If you’re performing this installation for a customer, ensure they understand this behavior so the vehicle can be operated safely. There will be no issues as long as the battery remains properly charged.

If you have any questions or need technical guidance, please contact us.

Compatibility

Supported battery types: Gen1 – Gen3
Not supported: Gen4 (commonly found in GT, 720S, and similar models)
