What is a good 2s lipo for me? I mostly go off road with my stampede and sometimes do street runs... I have stock gearing and mip cvds too.

I currently run the duratrax DTXC2177 8.4v batteries and would like a little more power/faster... but not 3s type of power since I find it to be to much power for such a truck.

Also if i get a 2s that has 8.4v does that pretty much mean that i will get about the same speed as my 8.4v nihm batteries i currently use?

What does the c rating accomplish?

Any advice?
