This module is most commonly used with all projects involving a Lithium-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 it will automatically disconnect the circuit and protect your battery.

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