captain harlock, I only have 2s, 3s and 4s lipo packs and I am very satisfied with there performance on the track with the 4s. Plus I don't want to kill my brand new MMM on purpose, I'd rather let Castle handle the stress testing. I just want to run my buggy/truggy without any issues. May be down the line when Castle figures out what is causing the failures with some of the MMM I would like to try a 5s pack, just to see the difference in performance (speed, temps, etc).
