【What it does】: The lithium battery charging module adopts the Micro USB female socket design, which can directly input the rechargeable battery with the mobile phone charger, and still retain the input voltage wiring pad, which is convenient for DIY.
【Power Indicator】: The onboard power indicator light of the module, red means charging, green means fully charged.
【Specification】: Input voltage: 5V, charging cut-off voltage: 4.2V±1%, maximum charging current: 1000mA, battery over-discharge protection voltage: 2.5V, battery over-current protection current: 3A.
【Note】: When the battery is connected for the first time, there may be no voltage output at the OUT terminal.It is necessary to connect 5V to the power input terminal to charge it and activate the protection circuit.When using a mobile phone charger for power supply, it must be able to output more than 1A, otherwise it may not be able to charge normally.
【Application】: Module comes with integrated protection.Widely used in 16850 battery charging, 3.7V lithium battery charging.
