The X2 can use the T3. In fact, Smokeless Image has made their own T3 to be compatible with their X2's.
A Vivi Nova will not work on the X2 or any other 808 device without a 510-808 adapter. The Redux is a Vivi Nova clone for 808's, but I've never used it.
Just for the sake of clarity, the X2 is a vGo/iGo device. Some vendors use 808/eGo which just serves to confuse things even further. An eGo is a 510 fat battery with an additional set of threads. A vGo/iGo is an 808 fat battery with the same additional set of threads. A few delivery systems, such as the T3, screw on to these additional threads; however, in most instances these threads are used by a cone to cover a standard cartomizer. Delivery systems made for the fat batteries, like the CE4/Stardust, have an empty skirt that covers these threads. In both instances, cone or skirt, this is solely to provide an ascetic look.
The 510 connection is the most popular connection on the market. This means there are more delivery systems available for that connection, but there are also more opportunities for things to go wrong or perform poorly.
A Volt X2 is a 3.7v regulated battery. Except for when it is fresh off the charger, when using it as a pass-through or when it is about to die, it will deliver a constant 3.6-3.7 volts. Originally the eGo was a 3.4v regulated battery, I'm not sure if that has changed or not. I do know the kGo and Echo-E batteries are also 3.7v 510 batteries, but in general 510's operate at a lower voltage than 808's before getting into the realms of variable voltage devices.
Either device will give you what your looking for, which is a long lasting battery with multiple cartomizer and clearomizer options to vape your nicotine with. Some people prefer one over the other, some use both and others are still happy with their 4081's and carts.
Hope this helps a little.
Good luck!
