This module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. In addition to safely charging a lithium battery the module also provides necessary protection required by lithium batteries. See below concerning the protection features this module provides.
This is a DC charging and discharging integrated module, with 5V normally open output, which is not affected by load access and has a maximum load current of 2A. It features 4 levels of charge/discharge electricity indication and button-controlled output.
It features 4 levels of charge/discharge electricity indication and button-controlled output. The module comes with a built-in power management circuit that boosts a lithium battery to 5V and supports charging and discharging simultaneously. Besides, it has battery protection which makes it applicable for batteries without a protective board,
Otherwise, you can directly charge from USB supply by using a USB cable. These two LEDs indicate the status of charging. When a battery is charging, Red LED glows, and when it is fully charged, the Green LED turns on. Lithium-ion battery charging and discharging module which supports a constant current – constant voltage charging mechanism.
The module will monitor the voltage of the battery as its being consumed by the circuit (load). When it goes below the critical value (3.7V) the module will automatically disconnect your battery form the load and protect your battery from over discharge.
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.
