I have run several tests with just the foil and from what I can tell, just starting off with a warm battery and reflecting the heat back to the battery with the foil, the difference is only a couple of degrees with the hand warmers.

When you get to the point of EXTREME cold, the foil may no longer be enough, but for up to 5 degrees below freezing (f), the foil does an outstanding job of holding in the heat.

I intend to test lower temps as the winter progresses.

the results for anyone else who tries this will be welcome.
Basic Flying Rules: "Try to stay in the middle of the air. Do not go near the edges of it. The edges of the air can be recognized by the appearance of ground, buildings, sea, trees, and interstellar space. It is much more difficult to fly there."
