The PB70-BMCC PowerBase-70 Battery Pack for Blackmagic Cinema Cameras from Switronix contains a 70Wh, 14.8V Lithium-ion battery designed to extend HD movie recording time for the Blackmagic Cinema camera. The included GP-DV-BMCC Interchangeable Regulator Block has a 12" cable. The PowerBase-70 delivers 6 times more power than the original battery supplied with the camera.
It is also intended to streamline your High Definition (HD) movie recording: the PowerBase-70 mounts under the camera and doubles as a grip, or can be attached to a camera support via its 1/4"-20 release plate or V-mount. Wired as a 14.8V battery pack, it can provide extended power for up to two additional 12VDC devices such as lights, monitors or HD converters as well as other devices requiring lower voltage (an optional XP power regulation cable is needed). The pack is also furnished with 1/4"-20 threads on either side to mount accessories.
