When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. You need charge it with 5V input to activate the protection circuit.
If the battery is short-circuited from B+ B-, you also need charge it again with 5V input to activate the protection circuit.
When using a mobile phone charger for input, please note that the charger must be able to output 1A or above, otherwise it may not be able to charge normally.
The TYPE C USB female socket and the +-pad next to it are the power input terminals, which are connected to 5V voltage.
B+ is connected to the positive electrode of the lithium battery, and B- is connected to the negative electrode of the lithium battery.
OUT+ and OUT- are connected to the load, such as the positive and negative poles of the mobile booster board or other loads.
Connect the battery to B+ B-, insert the mobile phone charger into the USB socket, the red light is on for charging, and the blue light is on for full.
