I have a slash vxl 2wd and want to go lipo. First question: will a 2s lipo improve speed/acceleration at all, or just give you longer, more consistent run times? Secondly, traxxas shows on their website a 25C lipo is the appropriate c-rated lipo. should I not go above 25c with my stock brushless system and other electronics? Lastly, whats a good mah rating to go with? I know it varies based on how you drive it, but what kinda run-time would I get out of, say a 7600 mah? thanks very much for the help - i'm totally new to lipo!
