Where to use TP4056 Charging Module:

This module is most commonly used with all projects involving aLithium-ion battery. As we know a lithium battery should not be overcharged or over discharged, hence this module will monitor the voltage level of the battery during charging and discharging. If the values go beyond critical value, the module will automatically disconnect the circuit and protect your battery.

So If you are looking for a module using which you can safely use your Lithium battery for both charging it and for connecting it to your circuit, then this module could be the right choice for you.

How to use TP4056 Module:

在使用锂电池时要小心总是好的。该模块用5V运行，可以由USB迷你电缆提供，该电缆通常用于充电智能手机。您可以使用任何类型的移动充电器及其电缆为该模块供电。如果您打算在没有电缆的情况下直接为其供电，则应将 + 5V连接到In +，并应连接到地面。

Lithium-ion batteryshould be connected as shown in the pin diagram above. The module does not have a reverse polarity protection, so be very careful while connecting your battery. Use a multimeter to check for the polarity of your battery, if connected in reverse your module will heat up immediately which would most likely kill it. If connected correctly and charger is turned on, the RED led will go high indicating that the battery is being charged. The charging process is controlled by theTP4056 Liner voltage ICwhose circuit diagram is shown below (the protection circuit is not shown)
