Pinout Definition
| IN | Power input (5V 3A) |
|---|---|
| OUT | UPS output (5V 2.5A) |
| GND | ground |
| UPS OFF | turn off UPS power output when connected to PWR pin |
| BOOT | Batteries activation (pull low for 500ms and then pull high) |
| CHARGE | Charge indication (low level indicates charging) |
| SCL | I2C clock |
| SDA | I2C data |
| PWR | UPS ON/OFF (turn off UPS power output when connected to UPS OFF pin) |
Note: When using pin headers for charging and discharging, it is recommended to connect all input and output pins for 2.5A output current to reduce pin stress

SAFETY CAUTIONS
- 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.
