drkros3, I'd race with a full charge before changing anything. You could also lower the cut-off a bit, to see if you can get the couple minutes you need. I run quark esc's with a max of 3v per cell cut-off and pull off when the cut-off first hits, I always get above 3v per cell when the car comes off. If bashing i see higher cut-off, but racing you might need the extra few sec's it could give
