OK, a tank w/ 2.0 carto should work just fine.....the tank uses either 2.0 or 3.0 ohm, so if you don't like the 2.0 you can just buy a 3.0 and put it in the tank and vape....
@Calypso53
The tanks just fit around the carto so you can really buy any ohm rating you prefer--I actually use mine with the steel-bodied version of the DCC's you're using.
I only found two references to LUX, the skinny cigarette-sized batteries and a slightly larger eGo-sized 900mah. Since you are calling it "the bigger battery" I will assume you have the 900mah (especially since I don;t think the skinny batts could handle 1.5 ohms, even in a dual-coil configuration).
Two things to keep in mind: if you're going under 2 ohms, make sure they're dual-coils. They'll burn through the battery charge a lot faster, but the single coil configurations (like the 1.7ohm M&P offers in their tank) will put way too much of a draw on that small of a battery and fry it. Also, be aware that even though the dual-coils may work for you, they may also suddenly stop. A lot of people report that the "fat batt" PV's at 1100mah and lower don't survive usage with atomizer/cartomizers under 2 ohms and a lot of people report no problems at all as long as their dual-coils. Since they work for you so far you seem to fall into the latter camp, but you should be aware that the batteries will probably need replacing much sooner than if you stuck to 2 ohms or higher.
