frankly we were racing on my track in my backyard. ( it was loads of fun emaxx erevo both with MMM and a slash with a sidewinder and 5700) we were about 20 minutes in when the emaxz with the 25C 8000HV's started to slow down a bit. we stopped and the MMM fan wasnt on and wasnt warm. motor hot to be expected and packs were warm but not hot. Lipo cuttofs on ESC hadnt kicked in

i then looked at the erevo and on one side the 8000 ("20C") pack was hot and puffed so much it deformed the battery tray right under my MMM. the batt had reached 140. of course this wasnt the one with the warranty. I have been using MA for 3 years and think Austin is a great guy but all of the discussion about overrated packs has cost me a fortune. i will relegate my remaining MA packs to slash and my 1/18th scale where they seem to do fine.

I ordered a pair of the zippys 11.1 5000 for the erevo and am going to try the Neu's or SMC's in the emaxx. might stay at 7.4 packs on the emaxx as the thought of my sons driving 50Mph around the 2 year old is scary....
