If you're going to run 6S in an E-Revo, you'll want around a 150A discharge to be on the safe side IMO.....mah (ie: 4000) x C rating (ie: 40C) = discharge. That example would give a 160A discharge. Even if you have say, a 25C lipo but with 6000 mah, that would give you a 150A discharge.

I wouldn't run those lipo's you have, too low a discharge AND runtime IMO.
