Sorry, super late to this party, and you've probably already picked something up, but I got a Marshall M-CT7 from B&H (
http://www.bhphotovideo.com/c/produ...ectronics_M_CT7_CE6_7_CAMERA_TOP_MONITOR.html), that has a Canon LP-E6 battery plate on the back. I wanted something for both FPV and on-set monitoring with a Canon DSLR, and this fit the bill quite nicely.
For FPV, I use an Immersion Uno receiver, which uses the same voltage range as the monitor. With a power cable splitter, one battery drives both the monitor and the receiver, and I'm certain I haven't come anywhere close to draining the battery through several flights with a gimbaled Phantom 2.
The monitor has both HDMI and VGA inputs, and comes with a sunshade and a battery. There are other flavors of this same monitor with battery plates for Nikon batteries as well as standard AAs, all in the same price range.
