Hello,

So I've been struggling with powering a used BMPCC4K I recently got. I bought it with a Tilta NP-F970 plate and three batteries (2 BATMAX 7.2V 7200mAh and 1 Coolshow 7.4V 7800mAh). When I try to use the 12v output to the 2-pin input on the Blackmagic, it opens at around 11.7V then starts dropping voltage until the camera switches off.

By reading the forums, most people said they switched to a dummy battery setup and that it worked, so I bought a dummy battery and connected it to the Tilta 7.4V output. The camera switches on, quickly drops the voltage and shuts off.

So now I have no idea what to do, would the problem be with the batteries, is it the Tilta plate? Is there any way to find out? I know the problem thankfully isn't in the camera because when I connect it with two-pin straight to a wall socket it stays on.

Just managed to score BMPCC OG off of eBay $350, looking for any and all tips, as a new owner, I’m aware of the battery issues but what else should I look out for. I do have M43 experience (lumix g85)
