1-100pcs TP4056 1A Lithium Battery Charging Board Module 18650 TYPE-C USB Interface Charging Protection Two-in-one

The circuit board has charging function and battery discharge protection function to discharge while charging

Module features and parameters:

Input with a TYPE C USB bus

You can directly use the phone charger as input to charge the lithium battery,

And there are still input voltage wiring solder joints, which can be very convenient DIY

Input voltage: 5V

Charging cut-off voltage: 4.2V ±1%

Maximum charging current: 1000mA

Battery overdischarge protection voltage: 2.5V

Battery overcurrent protection current: 3A

Board size: 2.6*1.7CM

How to use:

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 connecting the 5V voltage and charging it. If the battery is switched on from B+ B-, it also needs to be charged to activate the protection circuit. When using a mobile phone charger to do input, 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 base and the + – pad beside it are power input terminals and 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 loads, such as moving the positive and negative poles of the booster board or other loads.

Connect the battery to B+ B-, insert the phone charger to the USB base, the red light indicates that it is charging, and the blue light indicates that it is full.
