One thing interesting about having the 2.0 loaner is that I can drive my usual driving habits and observe / compare the PEM, Motor, and Battery temps..... What I'm noticing is that the 2.0 PEM is staying allot cooler than my 1.5 PEM. I peaked the 2.0 at 100F / 38C. It then recovered fast after that.... My 1.5 easily would rise higher than that when pushing it... granted it wasn't a blistering day but I was pushing it and expected the 2.0 PEM to go higher. So I'm impressed with that. Curious... did the 2.0's come with the dual PEM fan/Blower? I know that the 1.5 used inductive charging which built heat up on the motor and could rise to the PEM... but was there any other changes other than the obvious design that would make the PEM run cooler? I'll try to peak to see if the 2.0 has the dual blower... Battery and motor appeared to stay the same... although I saw the battery rise and drop rather quickly.... I do hear that the water pump appears to be running faster/ higher pitched when sitting so possibly its circulating the water through the pack faster to do a quicker cool-down from faster heat discipation.
