Dirty D. I was thinking of getting a uhhh, power wheels battery and running my lights off of that. I think they can be found in a 12v and are easily rechargable. I like the idea of using some power drill batteries too. Like you, I don't trust the engine for any voltage output other than the kill switch. I'm planning to get a rear moped hub, as soon as I can get some extra dough together. There's a guy down here who can lace one to my rim with some thicker spokes. While that's going on I was thinking about using a solid inner tube for the rear.
