Introducing the Battery Plate Compatible with Canon C400 This V-Mount Battery Plate mounts directly to our Camera Cage for Canon C400 and features the following outputs: PD USB-C, P-Tap, and 2 Pin as well as a PD USB-C input. The USB-C input is especially useful as it allows users to power the battery plate without having a V-Mount battery attached which is perfect for hot swapping or rigging the camera in lighter weight configurations. The Plate also features a swivel mount that allows users to easily access the camera's on-board batteries which makes this a great option for hot swapping.
