Power your Blackmagic Pocket Cinema 4K Camera from a V-Mount battery using this V-Mount Plate. The camera connection is integrated into the plate by way of a 16 Inch cable. Other accessories that require 12-16 volts of power can be connected to the built-in D-Tap on the plate. For rig integration, this battery plate includes a 15mm LWS bracket for mounting on a lightweight 15mm compatible rod-based rig. In this configuration, the battery attached to the plate can be used as a counterweight for shoulder-mounted setups. Made in the USA.
