I'm probably over complicating things, but I'm feeling lost when it comes to power solutions for camera rigs. P-Taps, D-Taps, battery plates, gold plates...ugh.
I love the idea of having a single battery to charge my camera, one or two monitors, audio gear, etc. But I'm confused as to what power equipment is required. Everything, I feel, requires a different voltage, so it's not as simple as getting a multiple D-Tap cable and plugging everything in. Or is it? It appears everything has a proprietary, or quasi-proprietary power requirement.
Here are my power requirements, in a fairly confined shoulder rig: Sony A7s, SmallHD DP-4 EVF, the Atomos Shogun when it arrives, and a Juiced Link A-Box (it's power is self contained but I do come across situations where I need one additional power source).
What I've found, as a solution, is an Anton Bauer battery and: a Wooden Camera A7s Gold Mount http://woodencamera.com/WC-Gold-Mount-A7-A7r-A7s.html
The Gold Mount has the A7 battery and a P-Tap accessory port.
I guess my question is what do I need to bring out of the P-Tap port to power a DP-4, a Shogun and another accessory? The DP-4 takes Canon LP-E6 batteries, the Shogun takes Sony NP-F770's, and I'd like a 12V accessory (but you can't have everything haha).
Thanks for the assistance guys! Sorry to ask such a long winded question, but these are those types of things that don't have many resources for education.
