OkieTrucker - Check out this web-site, it's one of the best informational sites and answers most of the questions we might have about batteries for RC use. If your answer isn't all ready there, send him an e-mail. I'm sure he has the answer if he hasn't all ready posted it on his site. It really is a great site for all of our battery questions and problems.
