Usage:

Type-c female socket and the + – pad next to the power input, access the 5V input voltage. b+ connects to the positive terminal of the lithium battery, b- connects to the negative terminal of the lithium battery. out+ out- connects to the load, such as the booster board. Connect the battery to B+ B-, plug in the phone charger to USB, the blue light is on, indicating that there is power access, the red light is flashing, indicating that it is charging.

When there is power at the input, current is obtained from the power output, if no power is connected, current is obtained from the battery and the output is automatically switched off when the battery voltage is below 2.5V.

Tip:

When the battery is connected for the first time, there may be no voltage output at the OUT terminal, you need to connect 5V to the power input to charge it a little and activate the protection circuit. When using a mobile phone charger for power supply, it must be able to output more than 1A, otherwise it may not charge properly.
