[E-Revonut]

Go with the NeuEnergy batteries! A 4900mah 3s will fiy, it's tight but they fit and stay cool. I run a 2s on the motor side and 3s on the esc side in series for 5s. Motor is a Tekno neu 1515 2.5d. I couldn't ask for more power or better temps. I have run the same motor esc on 4s MA packs with low gearing, didn't puff or over heat the packs, got a bit hot at 127* a few times but they went way out of balance!!! about .5 volts off within a pack. sent them in under warranty. I tried 6s but it was insane. 5s is controllable and plenty of speed, looking forward to racing this season.
