A significant limitation of the Black Magic Cinema Camera is the lack of an interchangeable battery. This is the solution.

The Switronix PowerBase is a power solution that adapts a V-Mount battery to be used with camera systems without a v-mount connection. This particular set is for the Black Magic Cinema Camera.

This includes a battery, quick-release plate, power adapter for the camera, and a charger.

The PowerBase features three p-tap outlets for powering accessories and/or charging.
