TP4056 1A Lithium Cell Charging Module with Micro USB

Description

TP4056 1A Lithium Cell Charging Module with Micro USB is a very efficient 3.7V single lithium cell charging module. It can not only charge 18650 cell but a wide variety of different sized and kinds of 3.7V lithium batteries. The heart of the module is a TP4056 IC that is an advanced lithium battery charging IC. The IC is built and internally programed to provide efficient charging to a li ion cell which increases the cell back up and life.

The IC also has a temperature input pin from which we can connect a temperature sensor NTC type. The temperature sensor must be attached with the body of the battery to detect the temperature of the battery while charging. The IC is also programed to disconnect the charging when the battery temperature goes above from a limit set inside the IC’s program. The module is also having two indicators LEDs also marked in the module pinout & details above. One LED indicates the battery charging in progress and when the battery become full charged it automatically gets deactivated and the another LED will become activated to indicate that the battery is fully charged.
