ok listen carefully kanger products good stuff. I love the aerotank V1s I have 3 of them using 1.5 ohm coils you cant go wrong. I use them on both my mechs; I have a smoktech 18650 turbo and an authentic paragon carbon fiber midnight edition. I use them on my MVP 2.0 except one the base threads are different want even touch the thread walls on MVP. I have T3d and mini unitank. I have used the 1.2 ohm coils too on my smok turbo mod. but here recently I bought a cloupor T5 and a blue carbon fiber edition IPV2 50 watt box. I have 3 RBA attys 18650 blue metal tobh, a silver plume veil, and a 28.5 silver tobh (I guess when I say silver I should say stainless steel). I run 0.8 on my attys; so I bought some .8 ohm coils for my aerotank and they want even work; plus my aerotank with a 1.5 ohm want even register on my ipv2. my nautilus works great on it. what is the difference between a .8 rba and a .8 bdc?
