5V 2A Charge and Discharge Boost Module 3.7V/4.2V

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. 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.

This tiny board is all you need to use a 3.7V Lithium battery. It charges as well as steps the battery up to 5V with up to 2A to power equipment like microprocessors and sensors. In addition to safely charging a lithium battery the module also provides the necessary protection required by lithium batteries. This module switches off when there is no load being drawn from it.
