Normally, I use SOC% as I don't trust any EV's Guess-O-Meter. Since the range was 269 at the Service Center and I had 158 miles range after driving 100 miles with a 2,000 climb in altitude, then had 270 predicted range miles after charging this morning, I think its dynamic, not rated range. Also, my experience with EV conversions I've had, the range changes after the battery has cycled several times. What I do know is this is a substantial improvement.Those are 270 'rated' miles, right?
I guess I can appreciate that my climate (?) is what drives mine up closer to 300 miles.
Initially I was concerned about the new battery being 350 Volts instead of the original 400. It all seems to work fine. We'll see what happens in warmer weather this summer.
