I'm trying to think of a solution to the battery problem when using my Bmpcc 4k and Zhiyun crane 3. I would prefer to attach a small battery to one of the mounting points on the Zhiyun. I ran into someone once who said he got a $30 12v battery off of Amazon that would power his BMPCC 4k for a few hours. I'm looking for something like that, or maybe a way to use NPF batteries or mount a Hypercore mini V-mount. Any ideas are greatly appreciated!
