Hello! Newbie Vaper here. I thought this build was okay but when I went to a vape shop and the guy saw I had a dual coil set up on my rda on a single battery -- he said it's unsafe or something without knowing what the actual build was. So I came here to ask if my build is okay. I'm working on an IPV-D3S 80w single 18650 mod with safety features like Min atomizer resistance (0.15ohm) using an LG HG2, Radar RDA with dual coils which I bought pre-built (since I'm only new and don't really know yet how to build properly). Here are the specs of the coils: 0.27ohm Half-Staggered Fused Clapton Kernel: 26GA*32GA*24GA A1 Wrapped: 32GA A1 set two of these up on my deck and it read as 0.15 or 0.14 ohms then I wick with cotton bacon prime. I realize now that I'm at the minimum resistance level with this dual build. I usually vape this at around 70 watts Is this safe? I don't really care much that this drains my battery quickly. I have spares which I alternate using and charging. If it's not safe, what are my options? Should I buy pre-built coils which are 0.4oms or higher so the dual coil build would be 0.2+? Or are dual coils really bad for my mod and I should either get a dual battery mod or get a single coil RDA? Or could I just do a single coil on this dual coil deck Radar RDA? I think building my own coil is not an option as of now since I don't have the time yet to learn all of that. Thanks. All I really care about is safety. Any help is appreciated. Thanks!
