I will also add that I'm not 100% convinced that using 110v long term doesn't hurt the battery. Charging will raise the temp of the battery and high temps will hurt it over time. Charging at 110v takes a very long time and as a result, your pack remains warmer for longer periods of time. If you are doing this every day, you may experience some added degradation as a result. Charging at L2 for only a couple of hours before you drive is better on the battery.
I'm coming up on three years of L-1 charging, and my battery stats (as of last Fall) are as good as or better than most other 2013s in my climate. L-1 charging raises the pack temp only slightly - your talk of "high temps" implies something that doesn't take place from charging alone. The ambient temperature has a much larger effect on pack temperature than does L-1 or L-2 charging.
