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.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
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.
