5. Setup Instructions

Follow these steps to set up your 40W Battery Charging Board:

1. Battery Connection: Connect a 3S LiPo 18650 battery pack (rated 11.1V nominal, with a full charge voltage of 12.6V and undervoltage protection at 10.5V) to the B+ and B- terminals on the board. Ensure correct polarity (B+ for positive, B- for negative) to prevent damage. Use the provided terminal cable for a secure connection.

   

2. Input Power Connection: Connect a DC power source (12.6V to 13.0V, 2A-5A) to the 'CH IN' port on the board. This power source will charge the connected battery and supply power to the output ports.
3. Output Device Connection: Connect your router or other peripheral devices to the appropriate output ports:
   • DC 12V/1.5A (x2)
   • DC 9V/2A
   • USB 5V/2A

   Ensure that the voltage and current requirements of your devices match the output specifications of the board. For DC outputs, standard center-positive polarity is typically used.

4. Power Switch: The board includes a switch (labeled 'SW' or connected via the 'Switch' cables) to control the power to the output ports. Ensure it is in the 'ON' position for operation.

6. Operation

1. Powering On/Off: Use the physical switch on the board (or connected via the 'Switch' cables) to turn the module ON or OFF. When ON, power will be supplied to connected devices and the battery will charge if external power is present.
2. Battery Charging: When the external DC input power is connected, the board will automatically begin charging the connected 3S LiPo battery. The charging process is managed by the board's circuitry.

   

3. Battery Percentage Indicator: The board features a four-stage LED indicator to show the remaining battery capacity. These LEDs typically represent 100%, 75%, 50%, and 25% charge levels. Monitor these indicators to understand the battery status.

   

4. UPS Functionality: In the event of a power outage, the board will seamlessly switch from external DC input power to battery power, ensuring continuous operation of your connected devices without interruption or rebooting. When external power is restored, the board will switch back and resume charging the battery.

7. User Tips

• Optimal Charging: For efficient battery charging and stable power delivery, it is recommended to use a robust input power supply of 13V with a current rating of 2 Amperes or more. Using a lower-rated power supply may result in the battery being constantly undercharged.
• 12V Output Behavior: Note that the 12V DC output ports are unregulated. The voltage at these ports will directly reflect the current voltage of the connected 3S LiPo battery, which can range from 10.5V (undervoltage cutoff) to 12.6V (full charge). The 5V and 9V outputs are regulated.
• Seamless Router Operation: This UPS board is designed to provide a smooth transition to battery power during outages, preventing routers from restarting.

8. Troubleshooting

• Battery Not Charging:
  • Verify that your input power source meets the specifications: DC 12.6V to 13.0V and 2A-5A. An insufficient power supply may not provide enough current for charging.
  • Ensure the battery is correctly connected to the B+ and B- terminals with the correct polarity.
  • Check the battery itself for any issues.
• No Output Voltage / Device Not Powering On:
  • Confirm that the power switch on the board is in the 'ON' position.
  • Ensure the battery is connected and has sufficient charge (check the indicator LEDs).
  • Verify that the external input power is connected and functioning, if applicable.
  • Check all cable connections for looseness or damage.
• Unclear Output Polarity (12V): The DC output jacks typically follow a standard center-positive polarity. If you are unsure or experiencing issues, use a multimeter to confirm the polarity before connecting sensitive equipment.

9. Maintenance

• Keep the board in a dry environment, away from moisture and liquids.
• Avoid exposing the module to extreme temperatures or direct sunlight.
• Handle the board with care to prevent physical damage to components or solder joints.
• Regularly inspect connections for any signs of wear or corrosion.

10. Warranty and Support
