I think most of us (possibly) are past the
experimental phases or pushing single 18650 limits by now, who knows, I could be wrong. But everyone here is very mature, smart, & safe, but just in case someone still has that wild hair up their ass and feels like living life on the edge, here's what works for me depending on what mech I'm using..
Best ramp up, flavor, and warmth (for me with
high amp batteries);
tubes/parallel boxes .1ishΩ - .25ishΩ
stacked/series boxes .4ishΩ - 1ishΩ
Usually any lower, way too hot for me, I'll start to "taste the coil", and some juices can't hang with that type of heat. Not my thing. I paid a lot of money to taste the juice I paid for, not going to boil it. I use 3mg/6mg nic btw. Vaping 5 years. Mechanical lover.
BTW, I wasn't lying about hot button. Never experienced it. Now, warm batteries, of course, in my crickets, but never hot button. I've even seen photos of people with burnt lips from atty's getting hot, lol. I guess their juice is so good they can't stop pulling..
