Lipo battery help for my E Revo?

[Hickoryhead]

I told you I was new. In the future I will continue the same theard. Thanks for the tip. As for the packs yes I will have one on each side. I will basicly be bashing but I also want to race. 1 E-Revo to do both. I have a stampede with a 2s2p 6000 mah. I love the handling. But when I put a 3s in it the speed is better for racing. This is where I get lost. I want to race and bash but don't want different batteries. Maybe there is no over all fix for this. I want it to be fast but made to bash.
