The McLaren Gen 4 12V Battery Emulator Kit is the world’s first solution designed to replace the factory lithium battery with a compatible 92Ah AGM battery or a non-OEM lithium battery without triggering low-voltage errors or battery-related faults.

Important Notice

Once the emulator is installed, the vehicle will no longer accurately detect or report low battery voltage. You must regularly monitor the battery’s charge level and should not rely on the battery information displayed in the instrument cluster.

Certain safety functions activated by low battery voltage—such as automatically lowering the windows slightly—may no longer operate. If you are installing this product for a vehicle owner, make sure they understand these changes and know how to monitor the battery safely.

The system will operate correctly as long as the battery remains properly charged. Please contact Project Gamma if you have any questions before installation.

Confirm Your Battery Generation

Gen 4 batteries are commonly found in the McLaren 720S, 765LT, and GT. However, some vehicles may be equipped with a Gen 3 battery.

Check the beginning of the battery part number:

• 16M or 22M: Gen 4 battery—use this emulator kit.
• 11M or 13M: Gen 1–3 battery—use our McLaren Gen 1–3 Battery Emulator Kit.

The McLaren 750S and Artura have not yet been tested. If you need an emulator for either vehicle, please contact Project Gamma and provide a clear picture of the factory battery and its part number.

Installation and Battery Requirements

Use a 92Ah AGM battery, as recommended, or a non-OEM lithium battery with specifications equivalent to the original McLaren lithium battery. Using an unsuitable battery may cause operational or electrical issues.

Always monitor the battery voltage manually. Do not rely on the instrument-cluster battery charge information after installing the emulator, as it will no longer provide an accurate reading.

Vehicle Compatibility

Before ordering, confirm that your vehicle has a Gen 4 battery with a part number beginning with 16M or 22M.
