6. Setup
- Connect Power: Insert the small end of the provided USB charging cable into the input port on the side of the U90E Charging Hub. Connect the larger USB end to a suitable USB power source (e.g., computer USB port, USB wall adapter, power bank).
- Insert Batteries: Carefully insert up to five compatible 3.7V LiPo batteries into the charging ports on the hub. Ensure the battery connectors are correctly oriented and fully seated.
7. Operating Instructions
- Once batteries are inserted and the hub is connected to a power source, the red LED indicator light corresponding to each battery port will illuminate, indicating that charging is in progress.
- The built-in smart chip provides overcharge protection. When a battery is fully charged, its corresponding LED indicator light will turn off or change color (depending on the specific model, typically off).
- You can charge one, two, or up to five batteries simultaneously. The charging speed may vary depending on the number of batteries and the power output of your USB source.
- Once charging is complete, disconnect the batteries from the hub and then disconnect the hub from the USB power source.
8. Troubleshooting
- No LED light when battery is inserted:
- Ensure the USB power source is active and providing sufficient power.
- Check that the USB cable is securely connected to both the hub and the power source.
- Verify that the battery is correctly inserted and making proper contact with the charging port.
- Confirm the battery is a compatible 3.7V LiPo battery and not completely depleted or damaged.
- Slow charging:
- Ensure your USB power source provides adequate current (e.g., a 2A wall adapter will charge faster than a standard computer USB port).
- Charging multiple batteries simultaneously will distribute the available current, potentially increasing overall charging time per battery.
- Hub or batteries getting excessively hot:
- Immediately disconnect the power and batteries.
- Ensure proper ventilation around the charging hub.
- Do not use damaged or swollen batteries.
9. Maintenance
- Clean the charging hub and ports regularly with a dry, soft cloth to prevent dust accumulation.
- Store the charging hub in a cool, dry place away from direct sunlight and corrosive materials.
- Avoid dropping or subjecting the device to strong impacts.
10. User Tips
- For faster charging, use a high-current USB power adapter (e.g., 5V/2A or higher) if available.
- Always inspect your batteries for any signs of damage (swelling, punctures, leaks) before charging. Do not charge damaged batteries.
- Keep spare batteries charged so you can quickly swap them out and extend your drone's flight time.
