Regarding power, the BM5 uses a single Sony NP-F style battery. Like the SmallHD Focus monitor, you can use the power output of the BM5 to feed your camera via a dummy battery. On top of that, you have the option to power the monitor with an external battery by using the Lemo port on the monitor, and the included Lemo to D-Tap cable. The screen itself is a WLED panel, which is a marketing term to say LED panel, so blacks should be nowhere near an OLED panel.
In terms of construction, the PortKeys BM5 is entirely made out of aluminum. In front of the screen, there is a toughened glass in to protect it against shocks. It weighs only 350g. The BM5 is daylight viewable with an impressive brightness of 2000 nits and a viewing angle of 178°.
To mount the BM5 to your camera or rig, the monitor features a 1/4" hole at the bottom and one at the top. Also, an L bracket ? like the SmallHD Focus ? to mount the monitor more easily to your camera is available as an accessory.

The functions you can control are pretty basic at the moment: start/stop the recording, change your ISO settings, adjust the focus settings?etc. I think this is just the beginning.
