HW-357 3.7V 9V 5V Adjustable PCB Step Up 18650 Li-ion Battery Charge Discharge Power Bank Charger Module
This module is a small single-cell lithium battery charging module that also includes a 1A step-up (boost) converter for powering a large range of applications. The module will charge most types of single cell (3.7) LiPo batteries from either 4 to 7.5V power supply input or from a standard 5V USB port/adapter. A battery charge and standby LED is also included for visual indication. Besides battery charging capabilities this module also includes an adjustable boost converter which is capable of stepping up the attached battery voltage from 4.5 to 24V with a maximum supply current of 1A. There is no over-discharge protection for overcharge protection (2V cut-off boost is possible, but 2V output is still not blocked) Cut-off boost 2V, depending on the situation, whether to add a protective plate, For example, VIN + BAT + terminal of 5V solar panel can output 4.2V to 3.7V 18650 battery charging OUT + terminal output adjustable voltage need to be adjusted. It can be used for a multimeter and recharging the lithium battery.
