Silicognition LiFePO4wered/Pi+™ Battery Power System is a powerful battery solution for the Raspberry Pi, providing 20 minutes to 9 hours of battery power. Power times depend on the Pi model, peripherals, and system load. Silicognition LiFePO4wered/Pi+ fully supports usage as a UPS, allowing it to be permanently powered, even from intermittent power sources and solar panels, while providing conditioned power to the Pi. Mounting is recommended using the included 16mm M2.5 machine screws, M2.5 nuts, and 7/16″ nylon spacers for stability without stressing GPIO connections.
