This price is for one Sanyo/Panasonic GA 3500 mAh 18650, if you order 4 or more batteries, the price per battery is $6.50. This is new, bigger capacity 18650 made from a high quality manufacturer: Panasonic (used to be Sanyo). This is the most exctiing and new battery option to hit the market in a long time. Decent amperage (10A) for it's giant capacity (3500 mAh) making it perfect for such mods as the Sigelei 75w, Sigelei UFO 55w, and the ever classic IPV Mini 2.
This battery is the best of both worlds at a reasonable price and at the quality we expect from Sanyo (who is now owned by Panasonic).
Beware of clones, if the price is too good to be true it probably is. Read our article on legit or phony 18650.
For my first battery it's good. But dies fast within hours. But its fast to charge within minutes with the usb.?
