Product Details:

The Integrated Adjustable Module 2A (18650 Lithium Battery Charge Boost Discharge) is a versatile module designed for managing 18650 lithium-ion batteries in applications where boosting, charging, and discharging functionalities are required. This module is commonly used in power supply circuits, battery-powered projects, or portable devices that require regulated power output.

Key Features:

1. Lithium-Ion Battery Management (18650):

   • The module is specifically designed for 18650 lithium-ion batteries, which are widely used in power applications due to their high energy density, long cycle life, and reliability.
   • It can manage both charging and discharging of the lithium-ion battery, providing a complete solution for portable power projects.

2. Charging Capability:

   • The module supports charging of 18650 batteries using a 5V input (typically via USB). It regulates the charging voltage and current to safely charge the battery.
   • The module is equipped with a charging circuit that protects against overcharging and ensures the battery is charged at a safe current (typically 2A).

3. Boost Functionality:

   • The module features a boost converter that can step up the voltage from the 3.7V nominal of the lithium battery to a higher voltage (usually 5V or more).
   • This is useful when powering devices that require a higher voltage than what the battery can provide.

4. Discharge Functionality:

   • The module supports discharging the lithium battery to power connected devices, typically providing an output voltage of 5V (using a step-up boost converter) from the battery’s lower voltage.
   • It can provide up to 2A of current for discharging, suitable for powering USB devices or small electronics.

5. Adjustable Output Voltage:

   • The output voltage is adjustable, which is a key feature for providing the correct voltage needed for different applications. It is commonly set to 5V for powering USB-powered devices.

6. Protection Features:

   • The module is often equipped with important safety features such as:
     • Overcharge protection
     • Over-discharge protection
     • Short circuit protection
     • Overcurrent protection
   • These protections help prevent damage to the battery and module from extreme conditions.

7. Charging Indicator LED:

   • The module typically includes LED indicators to show the charging status (charging or fully charged).

8. Compact and Efficient Design:

   • The module is small, lightweight, and compact, making it ideal for portable or battery-powered devices. It's designed to work in applications such as DIY power banks, solar-powered projects, or battery backup systems.
