Many of the cheap batteries which can be purchased from Ebay and Amazon come from Alibaba, a large supply house in China. Andrew Wan, owner of AW, has publicly stated that all of the AW batteries from Alibaba are fakes.
Yeah... In todays day and age, it just doesn't take that much Technology to Print Shrink Bands and then Re-Wrap lessor quality Cells.
To me, Batteries are the Cheapest Component per Hours Used of all of my e-Cigarette Hardware.
I have No Problem paying a Dollar or Two More and buying a Battery from a Registered ECF Supplier. Or from a Company that has a Long Track Record of selling Batteries on the Internet.
With Mods Climbing to Ever Higher and Higher Wattages (and Prices), it seems Silly to me to try-n-save a Few Bucks by buying a Battery from e-Bay or Amazon from an Unknown Seller.
And if you Think about it for a Second. Legitimate Sellers have a Hard Time Selling a Genuine Battery on places like e-Bay/Amazon. Because the Price they have to Offer it for is Higher than what Joe Blow selling Knock-Offs can list his for. And since they Look Identical, who do you think gets all the Sales?
