50PCS Micro-USB 18650 Lithium Battery Charging Board 5V 1A Charger Module with Protection Dual Functions Description

Precautions: When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. In this case, the module When the block is connected to DC5V voltage and , the protection circuit can be activated. The battery starts from B+B-. If it is disconnected and reconnected, it also needs to be to activate the protection circuit. When using mobile phone charger When using the input power supply, please note that the charger and charging cable must be to support a current output of 1A. However, it may cause the module to be unable to charge the battery normally; When charging the battery, the load on the OUT terminal should be disconnected. The positive and negative poles cannot be connected incorrectly. Please follow the specifications. Use, otherwise the module be damaged. 1. Input voltage:DC5V 2. Charging cut-off voltage:42V+-1% 3. Maximum charging current:1000mA 4. Battery over-discharge protection voltage:2.5V 5. Battery overcurrent protection current:3A 6. The input end is equipped with a MICRO-USB female socket, and you can directly use a mobile phone charger to input power. Source to charge the battery; Instructions: 1. The MICRO-USB female socket and the + pad next to it are the power input terminals, and B+ is connected to the battery. Positive terminal, B- connects to the negative terminal of the battery. OUT+ and OUT- are connected to the load and can be connected to the mobile booster board Positive and negative poles or other loads. 2. Connect the battery to B+ B-, and insert the mobile phone charging cable into the USB female socket. The red light lights up to indicate charging. When the battery is fully , the blue light is on.
