RE: THE Official Traxxas E-REVO Thread
Higest c rating you can find, 5000mah 3s lipos. Flightmax 5000mah 30c 3s lipos would be a great choice. Not sure about the turnigy lipos though... They might be better or worse.. time will tell.
I have a 30c zippy 500mah 4s lipo in my revo,, it's great. I'm going to split it into 2 2s packs once I get my connectors in the mail.
