I want to welcome you to the board, and I hope you are able to get the equipment you need and are able to get off the cancer sticks. That said, I have to jump in and say I agree the quoted suggestion is terrible. This is nowhere near the equipment a beginner needs and even a very experienced person has no business building a coil that low under any circumstances. Ask me, it's a miracle the guy who wrote it is still alive. Whatever you do, don't do that.
My build is within the limits of my device on my settings.
Samsung INR 18650 25R are rated at 20 amp continuous power(35a burst), at .11 ohms running between 30-35 watts (depending on
juice strength) puts me between a 16.5 - 17.8 amp draw, that leaves me 10% headspace for continuous draw, and almost 50% for burst. (besides
vaping is done at a burst, continuous is for devices such as laptops, lighting etc.)
Pioneer4You IPV3 Li has a 40a Power handling capability so even if the batteries were to push their max burst amperage it's below the devices capability.
So while this may pushing the limits of what you deem acceptable, it doesn't go beyond what it was designed for or capable of. (please don't mistake any of this as me being hostile, tone is difficult to project in written word).
