you can power it using whatever you want, and methinks they decided to use a cordless drill battery (btw what gave you that idea? is it the right voltage?). But this is probably a good thing to take note of, as it should apply even if you are using the pwm power hookup (though I am sure I have hooked mine up backwards a few times so I dunno why ours is ok....? I actually managed to make ours track a target today. It was a great moment.) Im sorry to hear about your camera though.
