Lumenradio V-mount battery kit

Attaches to the sides of either of the units using two of the chassis screws. Plugs into the DC power barrel plug using the threaded barrel connector on the rear of the units. Allows for battery operation of the devices for several hours, depending on battery capacity. A typical battery of 190 Wh can operate Stardust for 10 hours and Aurora/Luna for 30 hours as transmitters, even longer if used as receivers.
