The Battery Personality Card provides an example of a Moto Mod™ with a rechargeable battery that serves the purpose of extending the battery life of a Moto Z smartphone. It can also be used as an example of how to provide autonomous power to a Moto Mod when not connected to a Moto Z. For this example card, a 300 mAh Lithium Ion battery is included along with a commonly used fuel gauge and charge IC.

This card plugs into the 80 pin connector that comes with the Reference Moto Mod.

As a developer, you can use this as a reference when designing and building your own Moto Mod prototype that needs it’s own battery connection. The source code for both the Moto Mod firmware and companion Android application is also available for your review and use.
