The PB70-GH4 PowerBase-70 Battery Pack is a 77Wh, 14.8V Lithium-ion battery designed to extend HD recording time for the Panasonic GH4. This battery pack comes with a base that accommodates the battery and a battery paddle to insert into the camera. It included GP-DV-GH4 Interchangeable Regulator Block and has a 24" cable. The PowerBase-70 delivers 6 times more power than the original battery supplied with the camera.
It is also intended to streamline your 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.
