My Aryia charged to 340 miles. I was traveling across the Smokies from Sevierville tn. to Cherokee Nc. it’s about 60 miles across the national park. Half way up the mountain my mileage drop to 241 miles… about 25 miles. Going from the top to the bottom it’s 25 miles. And I Gained 50 miles. I assumed its because of regeneration brakes. Now I’m at 280 miles. Going back going to the top of the park I was at 221, about 25 miles. Going down to Gatlinburg I’m now at 320. My complete trip was about 120 miles. When I got home I was at 301 miles. That’s 39 miles for this trip that was 120 miles. Is this possible.
