I purchased my HPWC almost 3.5 years ago for my old Model S. I was able to charge my Model S at 63 mi/hr at 80amps Apparently I can only charge my new Model X at 72amps max. To 72 A or not to 72 A? How fast is the maximum I can charge my Model X theoretically? 51 mi/hr? Why can't the Model X charge at 80a? Tried charging at 72amps yesterday and only charged at 36 mi/hr. Why? What is everyone else's experience charging their MX at 72A?
