Also, if you have a local tobacco shop, most of them sell EGO batteries now, but you may have to get a while starter kit. I know I can't just buy a battery at my local B&M, I have to buy a kit with battery, charger, and tank. But even that will only run me about $30 if I buy the cheaper one. Online, you have several options. I know NWVapors have a bunch of egos you can buy on their own, as well as Fasttech.
