tp4056 1a lithium battery charging panel module type-c usb interface charging protection two-in-one

This circuit board has charging and battery discharge protection functions, allowing for simultaneous charging and discharging.

Module Features and Parameters:
The input end is equipped with a Type C USB socket.
You can directly use a mobile phone charger to charge a lithium battery.
And still retain the input voltage soldering points, which can be very convenient for DIY.
Input Voltage: 5V
Charging Cut-off Voltage: 4.2V ±1%
Large Charging Current: 1000mA
Battery over-discharge protection voltage: 2.5V
Battery overcurrent protection current: 3A
Size of the board: 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 to charge the battery will activate the protection circuit. If the battery is disconnected from B+ and B- and then reconnected, it will also need to be charged to activate the protection circuit. When using a mobile phone charger as the input, be aware that the charger must be able to output 1A or more, or it may not be able to charge normally.
The Type C USB socket and the adjacent + and - pads are the power input terminals, which are connected to 5V voltage. B+ is connected to the positive of the lithium battery, and B- is connected to the negative of the lithium battery. OUT+ and OUT- are connected to the load, such as the positive and negative of the mobile boost board or other loads.

Connect the battery to B+ and B-, insert the mobile phone charger into the USB socket, and the red light will be on if it is charging, and the blue light will be on if it is fully charged.
