New Type-C interface
This circuit board has charging function and battery discharge protection function. It can charge and discharge simultaneously.
Module features and parameters:
The input end has a TYPE C USB female connector.
It can be directly charged by a mobile phone charger to charge the lithium battery.
And it still retains the input voltage connection solder points, which makes DIY very convenient.
Input voltage: 5V
Charging 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
Usage method:
Note: When connecting the battery for the first time, there may be no voltage output between OUT+ and OUT-. In this case, connecting a 5V voltage source for a brief charge can activate the protection circuit. If the battery is disconnected from B+ and B- and then reconnected, it also needs to be charged to activate the protection circuit. When using a mobile charger as the input, be sure that the charger can output 1A or more; otherwise, it may not charge properly.
The TYPE C USB socket and the + - pads beside it are the power input terminals. Connect to a 5V voltage source. B+ is connected to the positive pole of the lithium battery, and B- is connected to the negative pole of the lithium battery. OUT+ and OUT- are connected to the load, such as the positive and negative poles of a mobile boost board or other loads.
Connect the battery to B+ and B-, insert the mobile phone charger into the USB socket. The red light is on when charging is in progress, and the blue light is on when it is fully charged.
