This is a Micro-USB Lipo charger designed for single-cell 3.7V lithium batteries. The compact size makes it easy to integrate into your applications.
The charger adopts a TP4056X lithium battery charging IC, which guarantees you quick and safe charging. Three output current modes can be easily switched by selecting different bonding pads on the backside (the default output current is set to 50mA). The thermal feedback inside the TP4056X can automatically adjust the charging current to limit the chip temperature under high power operation or high ambient temperature conditions.
Plug this charger into a power source via its micro USB port and the onboard LED will let you know what's going on - the LED on the charger will flash when no battery is not connected; keep on when charging and go off when the battery is fully charged. You can also connect an external indicator which allows you to easily check the charging status when this module is integrated into your projects.
There are 3 charging stages provided: trickle charge, constant current charge and constant voltage charge - which guarantee safety and save charging time.
Note: The low-current mode can charge large-capacity batteries, butthe high-current mode cannot charge small-capacity batteries.If the charging current is too high for the battery, it may cause battery damage or even explosion.
Always check your batteries C-rating and match to the charge rate!
