If you were running about the same amp draw as when it puffed initially, then ambient temp may be the diff. How much cooler?
Thats not enough voltage diff to worry about. I've read that the hardest thing on a lipo is running it to the lvc - beginning to think thats what's going on here, if you had run it to the same voltage as the initial run, prob would have had it puff again and get hot.
Def wouldn't run it to the lvc next time out just to check. Maybe you need to raise lvc?
when it puffed i was mostly just messing around. never really mashing the gas, but i did get it going pretty quick a few times. mostly just mobbing over grass and the street. i drove it pretty much the same. the ambient temp was the same because i drove it both times in the morning, around 7, so it was like 65 both times. i know the normal lvc is 9.0v, but from what ive learned with one of my other hobbies (flashlights. i know, dorky, lol) you dont want to bring a li-ion or a lipo below nominal if you can help it, so thats why i have my lvc at 9.6v as opposed to the normal 9.0v. i know thats still 3.2 per cell, but thats still higher than 3 per. like i said, when it puffed, there were at 10.1, so they were fairly close to nominal voltage. im going to take it out in a few and see what happens. its 90 something right now, so that could effect it.
