Lipo - 25c 5100 or 30 c 5000 ???

Certainly. Since we know the specs are accurate on those cells, they should be fine for putting out around 120amps+, which is more than adequate. Gear for about 40-45mph when you have the MMM system, and they will be fine- just set the LVC for about 3.2-3.3v per cell to give yourself a little headroom and protect your investment. I know thingy* on the traxxas forum had some of the hardcased Enerlands (25c 5000mah, but you dont need the hardcase in the Erevo), and he loves them compared to his MA stuff, so I cant say fairer than that really.

*forgotten his name again, lol.
