I've just finished a dual coil build. My first actually.
I did 2 coils of 28 gauge, coming in at 0.48ohm total. I was aiming for 0.7 but I overdid it a little...
I'm using an AW IC 18500, those with a black wrap and red words.
So bottom line is; is my set up safe to use? If not, what is the safe resistance for the battery? I understand that not many people uses this battery, but I use the 18500 exclusively as my flashlight uses the same batteries.
Please do advice. I'd also love to hear how you vets build dual coils that are effective and accurate all the time. I'm having some difficulties maintaining the same resistance on both coils, while keeping them tight and round.
