Yeah the "ressurectors" are just a nickname that CCV gave them, they are the Smoktech 1.7ohm LR XL cartos. Like madjack said, you can get them from Hoosier as well, but CCV does have a good deal and free drip tip if you get 15, plus free shipping which is nice if you just want to order cartos.
If you ever want to try a tank for your kGo, I would try the Smoktech3.5ml tank. It's cheap and you can get it from CCV and Hoosier for about $10, plus it comes with a pre-punched 1.5ohm dual coil carto in it and a drip tip so it's an even better deal, and it works great. Personally I don't like dual coils like I said before so I just took it out. You can punch your own and use any XL carto you want in it, or of you find you like the Ressurectors, CCV and Hoosier both sell pre-punched smoktech 1.7ohm XL cartos to be used in the Smoktech tanks. They even have the metal base on them like the DC carto that comes with the tank. You don't have to use a carto with a flanged bottom, but it is kind of nice bc the metal base stops the tank from being able to slide down. There also is a bigger 6.5ml tank, but I think that bigger tanks look kind of awkward on kGo/Epower sized PVs, plus they make the PVs really top heavy. The 3.5ml tank doesn't look weird and it's about the same diameter as the battery tube so it doesn't make it topheavy. If you ever want a more maintanace free vape, for $10 it's def worth trying one. Even the 3.5ml tank is smaller, I fill mine up in the morning and can easily go all day without needing a refill. I have 2 juices that I vape throughout the day, and have a3.5ml tank for each one. I really like it bc if you fill the tanks in the morning and use a fully charged battery, the Epower and kGo have long enough battery life that you can vape all day without needing a refill or new battery, yet their still small enough that I can carry it around in my pocket with a tank on it, and easily carry the other tank too
