Hello everyone this would be my first post as a member to this site but I have been browsing as a guest for quite some time to gain some very insightful information. This site seems to have a broad spectrum of vapers which I do appreciate. I'm fairly new to vaping, started with the typical ego I bought from a shop down the road and have worked my way up to my current set up of a Spire by Beyond Vape mod, 18650 batteries and a nautilus mini tank. A friend of mine at work bought the Aspire CF Mod with the atlantis and I tried it and immediately fell in love. I did some research and saw a lot of warnings about sub ohm vaping which I'm not too familiar with. I know the dangers of using a mod that won't tolerate sub ohm power. I wanted to know if I could use the atlantis with .5 ohm with my spire mod, without having to buy the attachment. I know that it puts out at 4.2v which made me curious because I usually go at 6.0v with my 1.8ohm coils in my nautilus. My question is could I use the .5ohm atlantis coils on my spire, and what would be a suitable voltage/wattage to use it? I thank you all in advance for reading my post.
