Ego batteries are regulated at 3.7. You are going to want to run a low resistance (LR) cartomizer with an eGo battery.
The smoketech you asked about will work, but some people complain about the quality.
The Boge cartomiser you linked will also work, but i do not know what resistance it is, so I would not recommend it.
Also, the cartomisers you linked are over priced. You should check out crystal clear vaping. Boge 2.0 carts work well, and if you get a pack of 15 they are about $1.50 per cartomiser.
You can also get the "Resurrectors" there and users report often they are better than the Boge 2.0 carts.
However, like Chemsoldier83 recommended, getting a tank is a good idea. I have the same tank from madvapes and it works great with the 1.7 single coil cartomiser. And just about any tank is a good option.
