Nice thread! I knew almost all of this already, except for the part about max discharge dropping after many cycles. I've never gone below 0.8 ohm, that has more than enough TH for me considering the very high VG e-liquid I'm using. After 25 years of smoking, the last 15 being RYO, I like a warm vape. Using high to 100% VG makes this hard without very hot coil and often I have to sacrifice an "ideal" vape for what I consider to be "safety".
I've found myself answering the types of questions addressed here many times in the past. Judging by what I've read here I haven't strayed from the information as I am usually even more strict regarding safety. I've also run across quite a few folks that refuse to believe that sub-ohm vaping is at all necessary, and that sub-ohm vapers are "stupid" or "show-offs". Some folks are so opinionated that "YMMV" and "to each their own" is taken as an insult to intelligence. Be that as it may, you can't talk me into buying a Provari and I probably can't talk a 2+ohm vaper into using a mechanical (unless they just like collecting mods). Personally, I can get the same vapor and even better flavor from micro-coils than a standard wrap of half the resistance, but that also depends greatly on the atty used. Some rebuildables like the Hercules/Ithaka are made for dual coil; even with 2x 1.8ohm coils (for ~0.9ohm total) I am just as happy using a single 1.8 ohm micro-coil in a very small RDA or 1.2 ohms in a 22mm genesis atty. I'm not sure if "apples to oranges" applies here, but it's close enough.
Again, thanks for the consolidation of information regarding sub-ohms and battery application. This is going to be very helpful to those that can find it, especially with the huge rise in 18350 mechs and 14500 mechs as well. Like replicating a motorcycle stunt, some folks are going to get hurt when cloud chasing and vaping doesn't need bad press.
IMO, sub-ohm vaping and accidentally shorted atomizers do apply to APV use. I've had a Vamo sizzle, pop, and permanently fry from a shorted atty that read 1.8 ohms. I don't have any idea if this could have caused a runaway battery, it should not have fired in the first place. Most users will not be able to detect any issues with an APV other than a DOA unit but there is much more that falls under QC no matter how much the PV costs or who makes it. Understanding ohm's law and battery limitation is very important, but any small item containing lots of energy is never going to be 100% safe.
Please pardon my verbosity. These are only my opinions, YMMV,
, etc.
Edit: Multimeters... after getting 3 (2 just for vaping purposes), they are worthless to me for checking ohms so I bought an 510 ohm reading meter box. The DMM is just fine for checking continuity/shorts and battery voltage, but they vary too much even after subtracting for the resistance of the leads. Luckily they are are in stock far more often lately, and worth every penny.
