Setup Instructions
- Battery Installation:
Insert two 18650 Li-ion batteries into the battery holder. Pay close attention to the positive (+) and negative (-) markings on the board and the batteries. Incorrect installation will damage the module. Ensure the batteries are 65mm in length. The module supports two series-connected 18650 cells (nominal voltage 4.2V each).

- Charging the Batteries:
Connect a Micro USB cable to the Micro USB input port on the module. The charging current is approximately 600mA-800mA. The module will charge the installed 18650 batteries.
- Connecting to Devices:
Use the designated 3V output ports (1A max) or 5V output ports (2.2A max) to power your electronic projects. The USB 5V output port can also be used for devices requiring 5V power.
Operating Instructions
- Powering On/Off:
Use the ON/OFF switch located on the module to control the power output to connected devices. Ensure the switch is in the "ON" position for power delivery.
- Voltage Outputs:
- The module provides 3V output at up to 1A.
- The module provides 5V output at up to 2.2A.
Connect your devices to the appropriate voltage output pins based on their power requirements.
- Charging Status:
While charging via Micro USB, the module's indicator lights will show the charging status. Refer to the product's visual diagrams for specific LED indications.
Maintenance
- Keep the module clean and free from dust and moisture.
- Avoid exposing the module to extreme temperatures or direct sunlight.
- Regularly inspect battery contacts for corrosion and clean if necessary.
- Ensure batteries are properly seated to maintain good contact.
Troubleshooting
- Module Not Powering On:
Check if the 18650 batteries are correctly installed with the right polarity. Ensure the ON/OFF switch is in the "ON" position. Verify that the batteries are charged.
- No Output Voltage:
Confirm that the module is powered on and batteries are charged. Check all connections to the output ports. Ensure the connected device is not drawing more current than the module's rated output (3V/1A, 5V/2.2A).
- Charging Issues:
Verify the Micro USB cable and power source are functional. Ensure the charging current is within the 600mA-800mA range. If using protected 18650 cells, ensure they are 65mm in length, as longer cells may not fit or make proper contact.
- Automatic Shutdown:
The module may have an automatic shutdown feature if the load is too low (e.g., less than 90mA) for an extended period. This is a design feature to conserve battery power. For very low-power applications, consider if this feature is compatible with your project's requirements.
