SWIT KA-B21S V-Mount to B-Mount Conversion Plate

The KA-B21S lets a crew that already owns V-Mount batteries power a B-Mount camera without buying a second battery standard. It accepts a V-Mount pack at 14.4V, 26V or 28.8V and passes that same voltage through to the B-Mount camera side, so the battery's native voltage is preserved rather than converted.

An aluminum CNC unibody housing keeps the plate rigid under the load of a cine body, and SWIT recommends its own PB-H290S bi-voltage battery, or any 26V/28.8V high-voltage V-Mount pack, for cameras like the ARRI ALEXA 35 or Blackmagic URSA Cine that need that higher voltage.
