Storage of LiPos is one thing, but operating temp is another, LiPos want heat. They become almost useless at low temps. In fact up to a certian limit the warmer you keep them the more current you can pull out at one time.
A friend is building a backpack plasma cutter based off of heated LiPo batteries.
Um I DO think so. According to your wikipedia article, quote
"According to one book,[10] lithium ion batteries should not be frozen (should not be stored under -40 °C), because most lithium-ion battery electrolytes freeze at approximately −40 °C (this is much colder than the lowest temperature reached by household freezers, however).".
Even so this article is talking about battery aging over time, not battery performance in one charge. My Sony HDR-HC1 HD camcorder has a sony M series lithium battery, and it usually runs for an average of 1hr (or less) recording time. However, when I was shooting at 24 degrees F, the battery lasted less than 15min.

Uhh, I don't think so. Lithium Ion batteries (I'm going to guess the JAQ uses LiIon) actually hold a charge BETTER when they're cold.
