Micro USB 5V 1A 18650 Lithium Battery Charger Module Charging Board With Protection Dual Functions TP4056 Li-ion

Input voltage: 5V

Charge cut-off voltage: 4.2V + 1%

Maximum charging current: 1000mA

Battery over - release protection voltage: 2.5V

Overcurrent protection current of battery: 3A

Module features and parameters:

The input terminal is Micro-USB, which can be charged directly to the lithium battery by mobile charger.

And still retain input voltage connection solder joints, which can be very convenient for DIY.

Usage method:

Note: when the first access to the battery, there is no voltage output between OUT+ and OUT-. When the 5V voltage is charged, the protection circuit can be activated, and the battery will need to be charged from the B+ B- to activate the protection circuit. When using mobile phone charger to input, pay attention to charger must output 1A or more, otherwise it may not be charged normally.

The Micro-USB mother seat and its side + pad are the power input terminals, and connect to the 5V voltage. B+ is connected to the cathode of lithium battery and B- is connected to the negative electrode of lithium battery. OUT+ and OUT- connect to the load, such as the positive and negative poles of the mobile booster, or other loads.

Connect the battery to B+ B-, insert the charger of the mobile phone to the USB parent seat, the red light is charged, and the green light is full.
