Another new product has been added to the RTV inventory! this is not some normal eGo 650 mAh Battery this is the eGo T 2 Variable Voltage upgrade this battery does not only run at the normal 3.3volts but can be switched to 4.15volts with a couple taps of the button with the increased voltage you can really get the New Stardust clearomizers VAPING!! 5 out of 5 stars!! if you have been thinking about a battery upgrade then I suggest picking one of these bad boys up for sure! We have also restocked our inventory of 1000mAh and USB Passthrough batteries as well in MANY differnt Colors!!
