The SERIES-E is a new Variable Voltage battery, designed with performance and quality in mind. These batteries are rated at 1000mAh, so should last all but the heaviest vapers most of a day on a single charge.
As it features Variable Voltage, power can be adjusted to suit, with the user able to select from three separate settings; 3.7v, 4.2v and 4.8v.
The SERIES-E has been built for compatibility with the popular 18.5mm diameter tanks. It offers a flush fitting with the Aero Tank and Protank 3, however as a removable, solid stainless steel Ego-threaded ring is available, any 510/Ego tank will also work.
