OK cool, so this is totally doable then. Great. So, since I am stupid when it comes to all this stuff, can you break down for me what I would need to buy? I am cool with a crude setup, as long as it works and it runs for at least a few hours. If I can get what I need at Radio Shack, that would be awesome.

The unit has its own power button, but are you saying I should add a power button so that I can BE SURE it isn't drawing any juice from my batteries when not in use?

Also, what is a Gell Cell? Is this a good option? Something rechargable would be ideal...

Thanks for the help,

Bart

I had an old 7Amp Hour unit that would run things for ever, but anything from 2Amp hour and up should last a couple hours or more depending on size. I put an inline fuse of about 1amp, just incase, and used the plug in connector that came with the adaptor I had for the way to turn it on and off (You might put in a switch?). On the other hand you could just put Eight 1.5VDC batteries in series to get your 12VDC, but I don't think it's as nice of a package (Just my oppinion).

Based on the PDF:
Pin 1 is your +12VDC (red wire)
Pin 3 is your common (Black wire)
Unit draws .8Amps or less

Good Luck, taking those high altitude pictures!
