Description: Product introduction: Charging protection, prevent battery overcharge and over discharge, and automatically control the charging current to better protect the battery; type-c female interface, retaining input voltage solder joints, convenient DIY. Product parameters: Input voltage: 4.5V-5V Maximum charging current: 1000mA Charge cut-off voltage: 4.2V soil 1% Battery over-discharge protection voltage: 2.5V/3A Board size: 2.8cm*1.7cm Instructions: The type-c female and its adjacent + - Pad are the power input terminal, connected to the 5V input voltage, B+ is connected to the lithium battery positive plate, and B- is connected to the lithium battery negative electrode. OUT+, OUT- are connected to the load, such as the booster board. Connect the battery to B+, B-, insert the mobile phone charger to the USB light, it indicates that there is a red light flashing, indicating that it is charging. When the charge is full, the light stops flashing and turns solid. The load can be connected at OUT+ and OUT-, and the red light is always on after the load is connected. When there is power at the input, the current is obtained from the output of the power supply. If there is no power supply, the current is obtained from the battery. When the battery voltage is lower than 2.5V, the output is automatically turned off. Precautions： 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 activate the protection circuit. When using the mobile phone charger to supply power, it must be able to output more than 1A, otherwise it may not be able to charge properly.
