Uninterruptible Power Supply For Raspberry Pi
Supports Charging And Power Output At The Same Time, With Dynamic Path Management, Stable 5V Output
SAFETY PRECAUTIONS
- Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
- Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
- Do not mix use old batteries with new ones, avoid using batteries of different brands.
- When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
- Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
- Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
Features

Uninterruptible Power
It is able to charge the batteries and provide power output at the same time from external power supply. Automatically switch over to batteries output if external power supply is unavailable, keeps the system running without any trouble
* for reference only, please refer to the Package Content for the detailed part list
Dynamic Path Management, More Stable Power Supply
- When connected to the external power supply, the system will be powered and the battery will be charged at the same time, and the battery will be disconnected after being fully charged to avoid battery life damaging caused by frequent charging and discharging
- When the external power supply is insufficient, the battery will provide power output together with the external power supply at the same time to ensure system normal operation
- When the external power supply is connected, the system will keep running normally even when the battery fails or is taken out. And automatically switch over to batteries output if the external power supply is unavailable, keeps the system running without any trouble
