The Wooden Camera V-Mount Slide for C400/C300mkIII/C500mkII takes a V-Mount battery on a WC Pro V-Mount plate and feeds battery voltage to a Canon C400, C300 Mark III or C500 Mark II through a 4-pin XLR connector. Wooden Camera calls it the Battery Slide Pro, and the custom slide attaches directly to the back of the camera without rods.

It keeps the camera's battery compartment open, so an internal battery can still be fitted and batteries can be hot-swapped, with the DC input on the camera-right side switching between the block battery and the on-board battery. The battery plate slides to adjust its position and is held by a thumbscrew.

Three D-Tap ports supply battery voltage to accessories, and a digital fuse cuts off those accessory outputs while leaving the camera powered. The slide weighs 349.27 g and measures 152.4 x 101.6 x 44.4 mm.
