Maxamps and Neuenergy lipo testing

Good point though. The temp of the battery is also very important. I have some 25C lipos that won't put out 25C at 3.35v until I push em hard for a few minutes. Once they warm up the voltage actually bounces up a bit from 3.3 to 3.4v. It is with a prop load, not in cars but you get the idea.

I agree. I have spoken to FP on several occasions and they state that lipos do there best around 100-110 degrees.

This is def true. When I was trying to get my Crt.5 to hit 60 (4S 30C Neu 2500 pack) I had a hard time doing it until the cells got warmed up. It was ~40F outside, so it look most of the packs life in spd runs to get temp up. Consequently the fresh cool pack was only doing ~55, but the hot half-discharged pack got over 60. You could really feel the diff in the punch too.
