The Intro Kits only come with one battery. It is recommended to purchase a second battery if you smoke more than 3 Cigarettes per day.
The Pro Kits includes two batteries. So when your vaping and your battery has drained, you will always have a backup. Recommended: for 1-2 pack per day smokers
These Kits are the Wizbang of eCigarettes! A full charge on one of these batteries typically last a full day or more. You can expect extreme Vapor!
