Looking to drive to Hilton Head Island from Columbus, OH in the next few months in my S85. I was waiting for the Asheville supercharger to be built which just happened this year. So was looking for some advice from people who have charged there. I was planning on charging to 100% in Knoxville before heading up the mountains to Asheville. So when I reach Asheville how much should I charge to? My next stops would be either Greenville or Santee (if I can make it). I was mainly wondering about the elevation change from Asheville. Don't want to charge the car too high if I will be going downhill (regening the whole time) and regaining charge into the battery. What do you suggest?
