Hot lipos

Hey everyone. I just finished building my erevo and it is insane. I'm running a NEU 1515 1.5d with quark 125 and maxamps 5000 hv packs. The motor is 125-135F along with the speed control. Batteries are 135F after a 5-7 minute run. I had one pack puff and fail on me during the test run. It was 185F when i pulled it out. I had checked the temps on everything less than a minute before with everything in the 130-135F range. So I assumed it was a bad pack. I don't like the batteries this hot. I tried to find the gearing and temp calculator I saw posted here quite awhile back but am unable. Does anyone know where I can find it or able to post a new one.
