Description:
Note: There is no output voltage between OUT + IN and OUT when the battery is first connected. At this point, the protection circuit can be activated by turning on the 5V voltage and charging the battery. The battery is shorted to B + B and then connected. A load is required to activate the protection circuit. When using the phone charger input, please note that the charger must be able to output 1A or above, otherwise it may not be able to charge properly.
Mini USB socket and + - located next to it is the power input, connected to the B + 5V connected to the positive electrode of the lithium-ion battery, and B is connected to the negative electrode of the battery. lithium battery. OUT + IN and OUT- are connected to loads such as the positive and negative poles to push the motion of the board or other load.
Connect the battery to B + B-, plug the charger into the USB jack of the phone, the red light is charging, the green light is full
