Installation Steps

1. Power Off
   Disconnect all power from the LattePanda.

2. Install Batteries
   Insert three 3.7V 18650 batteries into the slots (observe polarity).

   Use high-quality cells (≥3000mAh recommended).

3. Connect to LattePanda
   Attach the 10-pin cable between the UPS board and LattePanda.

   Align the notch on the cable with the socket groove (foolproof design).
   

4. Power On & Activate

   • Verify all connections (polarity and cable seating).
   • On first use: Connect external power via Type-C or DC input to activate the board.
   • Press the LattePanda power button. The UPS and board LEDs should illuminate.
     

5. Check System Power Status

   • In Windows, the taskbar will show a battery icon with real-time charge level.
   • A lightning bolt (⚡) indicates charging when external power is connected.

✅ Critical: Always connect external power directly to the UPS board, not to the LattePanda itself, to ensure UPS functionality.
