So I'm hoping you and other folks here can help me work through the questions I asked.
Those are the numbers. What the marketing and stated stats are from individual companies is going to very. If you tell company "A" that company "B" says about there battery says theirs is ok in colder temp the will then tell you theirs will do the same so they don't lose a sale. Maybe you, as a scientist should read the technical white papers out there to get the real story.
