Samwise, glad you were able to identify your coils. The nautilus BVC coils come in different resistances: 1.8, 1.6 and 0.7. While I like all of them the 1.6 is currently my favorite. You may want to try out some of the different resistance coils to see how you like them, but the ones you have purchased will work very well for your tank. If you can manage to read it, each coil has different wattage recommendations on the coil, so you want to make sure whatever you are using, you are using it below or within the recommended "range." Generally a cooler vape *may* give you a longer life to your coil, though other factors also matter. Hope you are enjoying your new tank!
And hmmmn... There's another Nautilus tank using BVC coils.... *twiddling thumbs, looking away*. How does it vape?
