Critical Installation & Operation Notes
1.  Vehicle Coding Requirement
    The kit requires re-coding of the vehicle’s onboard system to recognize the AGM battery and disable lithium battery-related monitoring parameters. Failure to perform this coding will result in system errors.
 
2.  OBD Dongle Operation Steps
    - After replacing the lithium battery with the recommended 92Ah AGM battery, connect the included OBD dongle to the vehicle’s OBD port to automatically correct the battery configuration settings.
    - Once the configuration is successfully updated, the OBD dongle can be safely removed.
 
3.  Reversal Procedure Warning
    The OBD dongle is designed exclusively for lithium-to-AGM conversion. To revert the vehicle back to a lithium battery setup, a professional diagnostic tool is required (the dongle cannot be used for this reverse operation).
 
4.  Battery Capacity Mandate
    Only a 92Ah AGM battery is supported by this kit. Using an AGM battery with a different capacity will lead to system compatibility issues
