Yes, the nautilus is a tank with a 510 connection just like an RDA. Keep in mind though that this is simply the replacement top for a nautilus tank, it is not the whole tank. If you are looking for a whole tank, I can list one that would work well. Do you want to show me what type of mod you have (battery) and I can help you further
Be very very careful what types of tanks you put on that mod as it is an unregulated mod. Many older sub-ohm tanks have floating 510 pins and if you happen to put one of those on there you could very much short your batteries and explode your mod in your pocket. A good rule of thumb when using tanks on unregulated mods is to be absolutely sure you have a hard mounted or adjustable 510 pin. It is best to use RDA's only on those mobs, but you can use tanks as long as they are the correct kind like the griffin or other types of RTA's
