Module features and parameters:

The input terminal has a MICRO USB socket, which can be used to directly charge the lithium battery with the mobile phone charger, and still has the input voltage wiring solder joint, which is very convenient.

Input voltage: 5V

Charge cut-off voltage: 4.2V ±1%

Maximum charging current: 1000mA

Battery over discharge protection voltage: 2.5V

Battery overcurrent protection current: 3A

Board size: 2.6*1.7CM

Instructions:

Note: When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. At this time, the protection circuit can be activated by plugging in the 5V voltage and charging the battery. The battery is shorted from the B+ B- and then connected. A charge is required to activate the protection circuit.

When using the mobile phone charger for input, please note that the charger must be able to output 1A or more, otherwise it may not be charged properly.

The MICRO USB socket and the + - pad next to it are the power input terminals and are connected to 5V. 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 moving boost board or other loads.

Connect the battery to B+ B-, insert the mobile phone charger to the USB socket, the red light is charging and the green light is full.
