I had to get $2000 dollars in gold mount batteries from batteries4broadcast to power my rig for 12 hours.
The BMPC 4k pulls 30 watts of power plus my gefen wireless hdmi transmitter, small hd dp4 ,sdi to hdmi converter use approx. 20 watts.
I got the 4x 190 watt hour ones plus the 4x charger
I also had to buy 2TB of ssds and a black magic multidock
The viewfactor cage is nice. I also use an element technica micron dovetail system to easily adjust the center of gravity of the camera.
I use a DreamColor monitor with a HDLink pro as a lut box on a rolling stand for monitoring.
Needed a hdmi to sdi converter to convert the wireless hdmi signal to the hdlink's sdi input
