This battery offers a few key features which set it apart from many other e-cig batteries.
The iTaste VV utilizes an LED screen used to display voltage settings/adjustments and puff counter information. This battery can be adjusted from 3.5 to 5V in 0.1V increments. The battery also uses a microprocessor to automatically identify the resistance of your atomizer and provide a recommended voltage.
It also has a puff counter which keeps track of how many puffs one has taken since the device has been turned on. In addition to this, the iTaste VV has various protection features: 10 second cutoff for protection against accidental activation while in purse or pocket, short circuit protection against shorted atomizers/cartomizers, over-discharge protection which cuts battery off when discharged, and low voltage warning that signals when battery is below 3.3V and ready to charge.
This battery also uses a micro USB charger which can easily be replaced at any electronics store. This allows for this electronic cigarette battery to be used while charging.
