Description

The DC charging and discharging integrated module you described is a device that can be used to charge and discharge lithium batteries. It has a built-in power management circuit that boosts the voltage of the battery to 5V and supports charging and discharging at the same time. The module also has a 5V normally open output that is not affected by load access and has a maximum load current of 2A.

The module has four levels of charge/discharge electricity indication, which allows you to monitor the battery's charge level. It also has a button-controlled output, which can be used to enable or disable the output. The module has a built-in battery protection feature, which makes it suitable for use with batteries that do not have a protective board.

This module can be applied in a variety of applications, including car charging retrofit, driving recorder power supply, DIY mobile power banks, and mobile phone/laptop portable charging devices. It is a useful tool for managing the charging and discharging of lithium batteries in these types of applications.

Note:

The KEY function is invalid in charging mode. In discharging mode, short press the button once to enable output, and the indicator turns on; Long press for about 10s to disable the output, and the indicator turns off this time. The indicator goes off after 35s when there is no operation in discharging mode. When charging and discharging at the same time, please enable input and output to keep a balance, thus extending module service life.
