For location lighting with the Practilite 802, this V-mount Battery Plate from Kinotehnik provides a convenient portable power solution. The sturdy aluminum plate easily mounts onto the light using the supplied two Allen screws, and the integrated cable plugs into the outlet on the rear of the Practilite 802 housing. This V-mount Battery Plate has an IP54 weatherproof rating to match the rugged weather-resistant construction of the Practilite 802. (NOTE: the plate is not submersible.)
