60 kw, 100% charge as of 12,500 miles and 4 month 3 weeks was 208. Almost at 13,500 and 5 months of ownership. Will update then, as I am doing range charges once/week during these cold days now. I have notices, since temps are holding steady at night at about 28 Degrees F, and high 40's during the day, my standard 90% Charge has been about 170, where as 60ish degree days and nights it goes up to about 180.
