Drove 31.8 miles, 12.1 miles in the morning and 19.7 after work, 30.9 total before the 2.9 min cell voltage yellow light came on.  Red light expected within a mile, so estimate 33 mile range.  But this involved several miles of steady ~20 MPH freeway traffic driving, and coasting and dropping to 20 MPH at one point since I was hypermiling and no one was behind me, which probably added a few miles compared to driving the speed limit. So count on 30 miles, or 24 miles to keep the pack above 20% capacity.
