Hi and welcome. I do not recommend a tank on a Tuglyfe or a clone of it. It can be done, but it shaves your safety margin. (I assume you are talking about an unregulated version. Flawless does make a DNA 200 version but I haven't seen any clones of it. If it was a clone it'd probably have a YiHi chip anyway as they're cheaper). Another problem with the Tuglyfe is it is a series mod. Really, that sort of thing is for advanced users who know what they're doing, not-- forgive me-- persons unsure about coil building. It's super easy to get in trouble like that. If you insist on trying it, don't use a coil below about .75Ω under any circumstances unless you have some verified 25A+ batteries. Don't believe the label, check out
Mooch's chart. Even with 25A batteries, don't go below .5Ω.
Vaping unregulated is something it takes a while to learn. You have to have a good knowledge of Ohm's Law and some confidence in your ability as a coil builder. Now, if you want to learn, fine: I, and many others here, will be happy to walk you through it. But even then, let's not start on a two-battery series mod, shall we? Safer alternatives are available. I strongly recommend you put the Tuglyfe in a drawer until you're ready for it, or sell it and buy something else.
Sorry for the bad news, and welcome to the board.
