My one thought there would be a concern about frying the battery with heat in the summer if it isn't.
Yes, it is a winter only project. I don't need a light (or heated gloves) in the summer!

EDIT: According to a dubius looking datasheet on the BT-10, the max input voltage is 12.8V.

This is great, it means I can not waste nearly as much heat in my regulator. I still want to regulate it down to maybe 7-9V, as running things at their maximum ratings for extended periods of time isn't a good thing. And besides, a regulator is maybe a dollar or so, while the BT10 is (now only 50-60 bucks). It was over 100 when I bought it.

This is great, now I can manage the heat much easier!
