I use only Zippys in both my E-Maxx and E-Revo. I've bumped up the gearing quite a bit on the E-Revo sometimes to 22/58 and do a one or two speed runs a week, perhaps for about 5 minutes each session. The batteries have held up fine. I agree Zippys aren't the greatest by any stretch, but at the price they are an extremely viable alternative and perfect for bashing with proper gearing. The only issue I've been having with them is one of my 4S packs has a cell which holds about 0.01v less than the rest. I'm pretty anal when it comes to balancing, and need the tolerance to be +-0.005V
