Correction: a company claiming to use Anker's battery technology (what is that? their battery packs are just standard Lithium-Ion or LiPo cells) is crowdfunding for stated purpose of allegedly creating a security camera with an unverified and hard to believe 365-day battery life. They state the one year of battery life is based on 10 videos a day, 30 seconds each. That means that on one charge they have 365 days of standby and 30 hours, 25 mins of video recording. All this plus self-discharge, and down to -4 degrees F (this is significant since extracting energy out of a Lithium-Ion or LiPo cell is rather hard at such low temperatures - you lose about 1/3 of the capacity, and see significantly lower cell voltage and higher internal resistance at -20C).
