Micro USB Lithium Battery Charger Module 3.7-4.2V Charging Board With Protection

Note: The load on the OUT terminal should be disconnected when charging.

Module characteristics and parameters:

The input terminal has a Micro USB mother seat. You can use the mobile phone charger directly to charge the lithium battery.

And still retain the input voltage wiring welding point, which can be very convenient to DIY

Input voltage: 5V

Charging cut -off voltage: 4.2V ± 1%

Maximum charging current: 1000mA

Battery overlap protection voltage: 2.5V

Battery overcurrent protection current: 3A

Board size: 2.6*1.7cm

Instructions:

Note: When you connect to the battery for the first time, there may be no voltage output between OUT+ and OUT-. At this time, you can activate the protection circuit by connecting 5V voltage. Need to charge the control circuit. When using the mobile phone charger for input, be careful that the charger must be able to output 1A or more, otherwise it may not be able to charge normally

Micro USB's mother seat and+ - -pad next to them are the power input terminal and connect to 5V voltage. The positive electrode of the lfucting lithium battery, the negative electrode of the lino-lithium battery. OUT+and OUT-connecting loads, such as the positive and negative electrodes of the mobile boost board or other loads.

Put the battery to B+ B-, insert the mobile phone charger to the USB mother seat, the red light is on to charge, and the green light is full.

It can be used for charging and discharge protection of lithium batteries such as 18650, polymers such as 3.6.7V, and other lithium batteries. A single or more parallel connection can also be used.
