My vacation just completed last night is a perfect example. If I lived and ate the way I did over the past week, I would be dead in a year or two, tops. But I don't and TBH, my job is likely what keeps me alive.

So its a balancing act but an easy one. If you are going on a trip and your first leg can be a longer one, then charge to 100%. The small hit to your pack is fine. Just don't make a habit of it. I have tried this on my 40 and found that the car easily outlasted me. This resulted in very short charging stints while I took care of personal needs. Once, I stopped at 65% due to a "coffee issue" Not sure it worked better and I "know" it won't when I have to start paying for charges.
So I left home with 60% one time and stretched my first stop out (almost a disaster) so I could get a good 30 min QC. Unfortunately the bathroom I had planned to used was closed and luckily I was able to make it to another a block away. It was a close call!
