    FAQ

    • Why are batteries not included?

      Due to international shipping regulations for lithium batteries, they cannot be shipped with the device.

    • Is Linux or macOS supported?
      No. Only Windows 10/11 natively supports the HID-UPS protocol. Other OSes cannot detect battery status.
    • How can I extend battery lifespan?
      Set DIP switch SW3 to 80%CHG mode to limit charging to 80%, reducing long-term battery stress.
    • Can I power external devices from this board?
      Yes. The screw terminal provides ~11.1V output from the 3-cell series. Ensure external load current is within safe limits.
