This Tilta Battery Plate is designed for use with the Tilta Camera Cage for Canon C200. It enables you to use a V-mount battery to provide greater battery life for your camera and also allows you to power external accessories via the battery plate's D-Tap and DC power outputs. For ease of use, the plate attaches to the camera cage's top plate via an ARRI-standard rosette connection on the right side of the top plate.
