Since I had to go into work in Redmond I decided to go to Snoqualmie falls afterwards, and then back to Monroe. The entire trip was about 70 miles, and I used 72% of my pac. I am not sure if my range is improving because of the warmer weather, or if the batteries are getting more cycles on them. Every thing I have read about the lithium batteries is that in the beginning the capacity actually increases before they start to loose capacity. It was a beautifully trip, and Mac preformed wonderful.
