is this a good race revo setup?

I havent charged them to the lower level specifically, but as soon as they get down to a static voltage of around 20-20.5v the Quark runs 6s lipo just fine. I did it using a watts-up meter in line with the packs just to see what the voltage was when it stopped cogging at start up. It doesnt take much of a voltage drop to make a pretty big difference.
