Yes it will work just fine. The battery life should be really good. If you want really good battery life, I suggest getting a set of LG HG2 (the brown ones) or Samsung 30r. Both are 3000mAh and will work great for your Nautilus X.
I believe a 200 watt mod is a bit much for a tank that operates at such a low wattage rating. Nautilus X coils are now rated at 1.5Ω (14-20 watts) and 1.8Ω (12-16 watts). You should have gotten an Aspire NX75 or the new NX30 that is coming out soon. Read about it here: https://forums.aspirecig.com/discussion/28899/aspire-nx30-mod-is-coming#latest
Why opening a poll for this ?
I would have taken the Archon instead, of course ...
I ordered some Efest 18650 3000MAH 35A
