first big trip out of city and I have a question. Left home with full charge (X100d). Made it with 44% left. Climbed to over 6000, and then down to 5000. Spent the night and charged to only 90% because wanted recombinant braking to slow us going down. What concerns me is battery wasn't full, it wasn't hot, but a little yellow triangle kept appearing, off and on. If it matters the average usage Over last 30 miles was -54. But battery was no where near full. Why the warning. Car worked perfectly.
