Fully compatible with all Raspberry Pi versions including the high-power Raspberry Pi 4.
The LiFePO4wered/Pi+™ is a high-performance battery power system for the Raspberry Pi. It can power a Raspberry Pi for up to nine hours from its battery (depending on installed battery size, Raspberry Pi model, attached peripherals, and system load) and can be left plugged in continuously.

The Raspberry Pi and LiFePO4wered/Pi+™ communicate with each other over the I2C bus. A command line tool, shared library and language bingings for Python and Node.js are available to allow users to easily access the data inside the LiFePO4wered/Pi+™.

Using these tools, the user can access system parameters and configure features such as the wake-up timer, auto-shutdown timer and auto-boot settings. Some of the parameters can be written to flash to make changes permanent even if the battery is removed.
