The Indipro Dual V-Mount Adapter Plate with 3-pin XLR connector to locking clamp is designed to power a variety of lighting via the 3-pin XLR connector. This product must be powered with two 14.8 or 26V batteries, as opposed to different voltage batteries at the same time. A 3-pin XLR powered device can be powered using the 3-pin XLR output that is located on the back of the plate. The plate can be easily mounted to any light stand via the industrial locking clamp. This dual plate is hot-swappable, so you can swap in a new battery without having to power down the light.
