This is an uninterruptible power supply (UPS) expansion board specifically designed for Raspberry Pi 5 Single Board Computer. It can be used as a mobile power supply, providing a stable 5V output with a maximum of 5A.
Its enhanced power management system can intelligently monitor the power status of Raspberry Pi 5 and automatically cut off power when Raspberry Pi 5 shuts down, thereby increasing usage time and battery lifespan. It supports power outage and power adapter failure detection, and can automatically switch to UPS power supply in the event of a power outage or adapter failure.
It can power on automatically when power is restored and can be completely shut down through software and I2C battery level detection. The automatic shutdown voltage can be set. Additionally, it supports fast charging with a maximum charging voltage of 3A, enabling quick charging. It is suitable for mobile power supply for Raspberry Pi 5 in various applications such as smart cars, outdoor equipment setups, and detection scenarios.

Safety Instructions & Warnings
1. It is essential to read and understand these safety instructions and warnings before charging your batteries. Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the instructions below may result in fire, personal injury, and damage to property if charged or used improperly.
2. Never make a wrong polarity connection when charging or discharging battery packs. Always double-check the polarity of the battery's connector to ensure that "+" is connected to "+" and "-" is connected to "-"
3. Do not mix and use old batteries with new batteries, or batteries with different brand names
4. Lithium batteries have a limited cycle life. Please replace old batteries with new ones when they reach their service life or when they are two years old, whichever comes first
5. When charging the Battery Pack, please place the battery in a fireproof container. Do not leave the UPS shield on wood material or carpet unattended
6. Keep the UPS shield away from children to ensure their safety
7. Do not apply power to your Raspberry Pi via the Type-C USB socket.
8. Do not use 18650 battery with built-in protection circuit
