5V 2A DC DC Charge Discharge Integrated Module For Lithium Battery Power Management Applications

The DC-DC Charge Discharge Integrated Module is a compact power management board designed for lithium battery charging, discharging, and regulated 5V output applications. The module provides a normally open 5V output with a maximum load current of 2A, making it suitable for portable power systems, DIY power banks, and embedded electronic devices. Its output remains stable and is not affected by load access, helping deliver reliable power for connected equipment.
The module includes a built-in power management circuit that boosts a lithium battery voltage to 5V and supports simultaneous charging and discharging. A 4-level charge and discharge indicator allows quick battery status monitoring, while the button-controlled output provides convenient power control. Integrated battery protection makes the module suitable for use with lithium batteries without a separate protection board, improving safety and simplifying system design.
