5pcs TP4056 Charging Module 5V Micro USB 1A 18650 Lithium Battery Charging Board with Protection

Input power (5v) can be provided via a Micro USB cable (cellphone charger) or by any 5V 1A power source wired directly to the input power pads on the circuit board. Before drawing power from the output pads you must activate the protection circuit by connecting a 5v power source to the input (via Micro USB or direct wire). The B+/- pads get wired to the battery and the OUT+/- pads go to your load. If you wire your load directly to the battery you will bypass the over-discharge and over-current protection, this is not recommended. Features Input voltage: 5V Charging cut-off voltage: 4.2V ± 1% Maximum charge current: 1000mA Battery over-discharge protection voltage: 2.5V Battery over-current protection current: 3A Indicator LED: red – charging; green – fully charged Board size: 2.6 * 1.7CM Original Equipment Manufacturer: WAVGAT, Guangdong China Package Including: 5 * TP4056 Charging Module
