ITEM NAME:100PCS TP4056 TC4056 Micro-USB 5V 1A 18650 Lithium Battery Charger Module C I5L9 100PCS TP4056 TC4056 Micro-USB 5V 1A 18650 Lithium Battery Charger Module C I5L9 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. Colour:blue Material:PCB Size:2.6 * 1.7CM Package Contents: 100x 18650 Lithium Battery Charger Module
