DC-DC Charge Discharge Integrated Module (5V/2A)

This is a DC charging and discharging integrated module with a 5V normally open output that remains consistent regardless of load access, supporting a maximum load current of 2A. The module is designed with four levels of charge and discharge indication, allowing for easy monitoring of power levels through visible LED indicators. A user-friendly button controls the output, making it straightforward to manage power distribution with a simple press.

Featuring a built-in power management circuit, this module efficiently boosts a lithium battery to 5V, accommodating the need to charge and discharge simultaneously. This means it can serve as the critical component for creating reliable power solutions, whether for a DIY mobile power bank or a mobile phone/laptop portable charger. Its advanced battery protection makes it ideal for batteries lacking a protective board, ensuring safety and longevity.

This module finds diverse applications across different scenarios, such as retrofitting car chargers, powering driving recorders, and supporting various portable charging devices. It is engineered to seamlessly integrate into complex systems, balancing input and output during concurrent charging and discharging to extend the service life of the module. While in discharging mode, a short press of the button enables the output, while a long press disables it, ensuring control is as simple as it is efficient.

In integration, proper wiring is essential for optimized performance. The module offers clear pin definitions and wiring instructions for charge and discharge or for charge-only and discharge-only setups. The LED indications provide real-time feedback, assuring users of the module's operating status and making adjustments easy and informed, enhancing the overall experience and functionality.
