Hi Peri, I didn't contact him, he called me as a courtesy for my dealer. It was during that call that I pinned him down a bit on the battery settings. It was over a year ago, and I am having difficulty locating the contact info that I had for him. As for your regen, are you in the eco mode? I also find that the regen is most noticeable after the top 2 bars have been used. I also work hard to keep the majority of my operations in the first 2 circles of the power use gauge, using the 5th and above dramatically reduces the range. Another useful habit to maximize range, is to gently squeeze the throttle when starting from a stop, rather than mashing it. Sudden inrush currents create heat at the controller, and the battery (excess heat and cold are the enemy of this technology). I find that I get my best range in June and July around here (in the Seattle area), 100-125 miles, if I am careful (even with the hills).
