  In this video I am showing you how to power your Canon DSLR for more than 6 hours for less than $55 battery included. 6+ hours of battery is enough really for any event. Plus the bit extra is that the battery now is outside the camera and its a battery which is build for film cameras, so these batteries has less problems with overheating. As most DSLR has issues with heating up as their batteries aren't really made for filming and using that much power the batteries heats up after a full hour of filming back to back or if you are filming in a hot area. But with this setup the battery first is outside the camera and enable to cool down better, but also these large Sony NP-F970 are build for large ENG cameras and can handle the power output much better without getting hot.Another thing is that the power indicator actually works and even would go into reds when the battery is low. However the low on these batteries still can film quite long with it in red before its really depleted.
  The main part what is needed is the NP-F970 battery plate this is where the battery will be placed to power your camera. I have chosen this version as it have few extra quirks making it better than other one but also being quite affordable. This one actually made to power a lilliput monitor but it also can be used to power LED lights and more. The great thing about this one is that there is a lock, so the battery would not fall out easily. Another plus is that there are allot of mounts on this battery plate, from plain veclro to attach to anything to a small L bracket seen on the shoulder rig setup above, but also standard 1/4" scew hole giving you tons of option to mount it anywhere you want.
