Pictures of the Tilta F970 Battery Baseplate fitted to the Tilta Cage. You can use the Batery Baseplate fixed directly to the bottom of the camera without the cage. It provides 7.4v and 12v outputs.
With a fully charged pattern NP 970 7800 mAh battery using the 7.4v output I am getting 1hr 35mins of continuous 4k Prores recording to the external SSD.
