I'm sure there's a Blitz thread there that you can wade through to find out what people are breaking if anything.

You should be able to pick up an AC powered charger for ~$40 or less and many places are selling good 5000mah or better lipos for ~$35. Since lipo shipping rules have changed, it's hard to get them out of country. But if you're in the US here's a couple you might try.

Value Hobby, SPC Racing, SMC Racing, Hobbyking

MAH is the capacity of the battery. The bigger the number the more capacity it will have and the longer it will last.

C is supposed to be the rating of how much power the battery can put out in terms of amps. There's no standard way to measure this and there's been lots of discussion on vendors claiming higher C ratings that what's real.

But in most cases a higher C rating will minimize the voltage sag (reduction in voltage a battery experiences when put on a load). You probably want a 40C or higher is my guess.
