I'm about to embark on an aggressive leg: 293 miles, in an XP100D with rated range of 289 miles. It's not freeway, so speeds are slower, which will help. And there's plenty of RV parks along the way for emergency top-ups. But I'm wondering: would it help maximize my range to put the car into "Max Battery Power" mode before departing to pre-heat the battery pack? Temps are forecasted to be in the upper 40s-lower 50s Fahrenheit, so I'm thinking this might improve my overall thermal picture. I'd turn the mode off before unplugging, of course! Would this work? Anybody tried it? Thanks for any insights you might have.
