I dug around CPF and google search for 15 minutes and that was about all I could find other than a comment from someone from someone(not affiliated with batterystation) about a "rumor" on a military contract. So unless you can find a post from batterystation on the matter I'm going to assume that I'm right :) Whatever the reason he switched it's a good thing. If my cells and a few other posters with similar issues are any indication, it's a good thing they did switch to US cells, as the chinese ones are inconsistent. I'm sure the chinese are perfectly capapble of making a top class battery, but I can't recommend them over similarly priced US made ones after experiencing the wonder of mismatched brand new cells firsthand.
