I think that particular battery would not be powerful enough to power the Red + Follow focus + Wireless video. It's rated at a 55W limit. I think the Epic itself already needs 50-60W. Remember, it's not just the capacity of the battery, it's also the rated power limit you can draw from it. I've been using Globalmediapro batteries to power my Epic for years now and they work great, but I use the 160W batteries which are rated at 79W max. They are able to power the Epic, a bartech follow focus with M-One motor and a Paralinx without a problem. Put they weight like 1 kg each, which is quite heavy for a Mövi setup. http://www.globalmediapro.com/dp/A2...S-R-Lithium-ion-Battery-160WH-for-Red-Camera/ Maybe the good compromise would be these 95 Wh batteries : http://www.globalmediapro.com/dp/A2...HW-R-Lithium-ion-Battery-95WH-for-Red-Camera/ They are rated at 70W, which maybe hopefully be enough... Probably depends on the accessories you need to power. They weight 710g.
