Lithium Battery Charging Module.

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 the necessary protection required by lithium batteries.

This module includes an over-discharge protection circuit to protect your Lithium batteries from discharging too much which can result in damaging your batteries. Lithium batteries charge at nearly 100% efficiency, compared to the 85% efficiency of most lead acid batteries. This can be especially important when charging via solar when you are trying to squeeze as much efficiency out of every amp as possible before the sun goes down or gets covered up by clouds.

Note: You will have to connect the 5V power correctly so as to not destroy the board permanently.
