We´ve got some 24/12V brick batteries (from our film camera) that we would love to use on the Red for tripod and dolly shooting just like we work now on 35mm. Most of these batteries come with two 4 pin 12V XLR outlets. With the proper power cable, would this bricks work with the Red One. Can we order our Red One with such a custom power cable ?.

I don't see why the wouldn't, they're only powered by 12v, not voodoo. I plan on making adapter cables as well. There's no way they pull more current than a film camera running high speed. There must be a million of those batteries out there and in a lot of situations they will be a better choice than the Red batteries.

I've heard that the amperage draw of the RED may be too high for standard film batteries to function properly.

I would be very surprised if this were true, I'll do some investigating.

Use a car battery.

Is there an official word on this ?. A tech paper or something now that the cameras are being shipped ?. The tech specifications on the Red.com says nothing about it. I´m ordering new batteries for our film cameras and I would like to make them Red ready but they cost more than the ones with just the 24V outlet so it would be good to know.

Yeah but not one of those British batteries. Aren't they still running 6volt positive ground over there?

We probably won't offer a 4 pin XLR to 6 pin LEMO cable Matt.
Most 4 pin XLR D.C power sources won't sustain enough power to drive a RED ONE camera and the typical accessories that tap off of it.
The RED CHARGER is an excellent power source to compliment RED BRICK batteries if you have access to A.C power.

Obviously depends on what your setup is.
Plan on about 6/8 amps drain if your battery last 90/120mins.
