I am looking at this battery, http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=63534 At 10c it is 30 amps and at 20c for max 10 seconds it is 60 amps, matches the evolv recommended battery pretty good as far as amp limits. Still getting around the mah vs ah vs amps thing of lipo packs but I think I am correct even though it is only a 10c/20c vs the 30c/60c of the recommended.
