I bought the Panasonic 2900mah protected 18650’s from fasttech and received them yesterday. They were to my door in the peoples republik of California in only 10 days! I can’t say enough about these batteries as the minute I opened the package I could see these were the real deal. Just in the feel and assembly of these batteries is a far cry from even my well made Chinese made tenergy cells. At 13 bucks and some change I don’t see any reason to cheap out on cheap cells any more because these aren’t much more than what you’d spend on lesser quality cells.
