Your nemesis doesn't have VV. It is going to put out whatever the battery voltage is. A fully charged 18650 is going to be at 4.2 and will drop eventually to 3.7 and lower. At 1.7 ohm, this is going to be a very small amount of power.
It will work but, IMHO, is not going to be a very good vape. I think you need to build it lower. I would recommend something at least below 1 ohm to start out and then if you want more power, you can drop it lower.
Also, I think there are many RDAs that are better than the Magma. Magma is pretty old design by now. Many members here still love it, but I would recommend researching some of the other more recent RDA designs before you spend $120 if you were planning on buying authentic. Or, at least, just find a clone to see if you like it.
