Delayed for 70 minutes at the border while they checked over my apparently unusual car. Sigh.
Currently at 177.7 miles, charged to 75% and will cell balance and check battery temperature with Leafspy before leaving here.
Good news is battery temp is almost exactly the same as it was three charges ago, hovering at 93.8°F. Six bars, but not bad after the mileage thus far. A sustainable speed probably.
If 6 hours 20 minutes yields 177.7 miles, 24 would project to about 673. Considering the 70 minute border delay and brief charging delays earlier, 700 still may be in the cards. All depends on battery temp and station access.
