Sorry about this but I couldn't find enough info to feel comfortable about these batteries yet. I bought this set from a recent recommendation on the Vapor Joe site. It was from an eBay seller with a 5-figure rating. I checked out Sun Vapors site and compared pics but their article is for VTC5s. Mine looked like the pics of the real battery except the UPC mark looks more like the fake and is on the opposite side from the other printing, like the fake they show, but again, they are comparing VTC5s.
