Description
The Project Gamma McLaren 12V Battery Emulator Kit provides a plug-and-play solution for McLaren owners who want to replace the factory lithium battery with a 92Ah AGM battery or another compatible non-OEM lithium battery without triggering battery-related system errors or low-voltage faults.
Designed for supported McLaren Gen1 through Gen3 battery-management systems, this battery swap kit allows the vehicle's electrical system to operate with a compatible replacement battery while bypassing the factory battery-monitoring behavior associated with the original lithium battery configuration.
The Project Gamma Battery Emulator is particularly useful for owners looking for a practical alternative to the factory lithium battery while maintaining compatibility with the vehicle's existing electrical system.
Battery Replacement Solution
McLaren vehicles equipped with the supported battery-management system are designed around a specific battery configuration. Replacing the original lithium battery with a conventional AGM battery or another non-OEM lithium battery can result in battery-management warnings, low-voltage faults, or other electrical-system messages.
The Project Gamma Battery Emulator is designed to address these compatibility issues and allow the use of a compatible replacement battery.
A 92Ah AGM battery is recommended for applications using this kit, although other non-OEM lithium batteries may also be suitable when their specifications are compatible with the vehicle.
Plug-and-Play Installation
The Project Gamma Battery Emulator Kit is designed for a straightforward plug-and-play installation.
No permanent vehicle modifications are required, and the system can be installed or removed as needed. This makes the kit suitable for both personal installations and professional workshops servicing McLaren vehicles.
Always follow the supplied installation instructions and verify battery compatibility before installation.
Battery Monitoring
After installation, the vehicle's original low-voltage detection behavior will no longer function in the same way.
Because the system will no longer report low battery voltage through the original battery-monitoring strategy, the owner must manually monitor the battery's charge level and maintain the battery in a properly charged condition.
The vehicle's dashboard battery or charge indication may no longer provide an accurate representation of the actual battery state.
For this reason, regular battery-voltage checks are strongly recommended.
Important Safety Notice
This product changes the vehicle's original battery-monitoring behavior.
Because low-voltage detection is altered, certain vehicle functions that rely on low-voltage detection may no longer operate as they did from the factory. For example, the vehicle's automatic slight window lowering function associated with low-voltage protection may no longer operate.
The vehicle should only be operated with a properly charged and maintained battery.
If this kit is being installed on a customer's vehicle, the customer should be informed about these changes before the vehicle is returned to service.
Supported Battery Generations
Supported:
- Gen1 battery systems
- Gen2 battery systems
- Gen3 battery systems

Recommended Battery
For AGM applications, Project Gamma recommends a 92Ah AGM battery.
A compatible non-OEM lithium battery may also be used when its specifications are appropriate for the vehicle.
Important: Battery selection remains critical. Always ensure the replacement battery has appropriate voltage, capacity, physical dimensions, terminal configuration, and electrical characteristics for the specific McLaren application.
Installation
The Project Gamma Battery Emulator Kit is designed for plug-and-play installation and does not require permanent modifications to the vehicle.
Installation and removal can be performed without permanently altering the vehicle's wiring or electrical system.
Professional installation is recommended for customers who are unfamiliar with McLaren electrical systems or battery replacement procedures.
After installation, regularly verify the battery's charge level and condition using an appropriate battery tester or voltage-monitoring device.
