I understand. I understood your first post
(a couple great posts btw)
You are in a minority of people who vape almost exclusively with fully mechanical devices across the board.
Actually I haven't touched a regulated mod in almost two years now, and, the last time I used a PWM mod I think was more than a whole year ago.
Which of course there's not a thing wrong with. It does however present you with considerations that most mech users don't deal with.
That's just because I like to explore the mech hobby for the sake of variation in several many ways. I guess most mech users just want to stick to using single battery mechs with 24mm or 25mm RDAs so they have no big interest in the niche-within-a-niche type of mech setups that present different types of challenges.
The vast majority of mech users I see are concerned primarily with finding the best combination of safety, performance and capacity at the upper-ish end of the amp draw.
Same here. But there exists no linear relationship between the vaping time and battery capacity, as the criterium to use for that is the energy, not capacity, albeit the energy depends on both the DC internal resistance and the capacity, BUT... the
effective capacity still factually depends on the amp draw so, in a real-world vaping scenario the capacity you'll get is quite a lot less than the mAh rating might have you believe. That's simply because the amount of charge that you've got left after the volts,
under load, dip below the desired voltage cut-off will not be used, and also it's because the battery's
efficiency still factually depends on both the DC internal resistance and the amp draw.
You are one of maybe 3 people that I've ever run into, that I can think of off the top of my head, who would use a 21700 at or below 20 amps on a mech. Again, NOT a criticism as there's not a thing wrong with that.
I never vape at or below 20A on a
single 21700 battery mech, though. It's just that, on the Vaperz Cloud Stormbreaker with three 30T batteries in parallel, at just 20A
per battery, you're actually pushing more than 245W, so... I hope that explains my point re possible ways to tame a hot build by picking a battery that hits less hard, merely as an alternative choice to discarding/redesigning the actual build in question─even if only to learn from that experience. That is, entirely from the hobby kind of perspective, i.e. as part of an ongoing self-educational process that enables me to keep wanting to explore various new possibilities. Basically, it doesn't have to be an all-day-vape type thing to still be useful, at least to
some degree. So that's the main philosophy I guess. It's the fun part of trying to design coils such that finding out how they can perform under a specific set of circumstances becomes the ulterior goal besides choosing to just vape the old familiar, or usual, way.
I've also only been in this game a couple years and change. Maybe I just haven't run into those people. I have run into quite a few though and almost all of them use a combination of mechs and regs with it kinda being assumed that their mechs are on the hotter end of their preferred vapes.
I actually dislike a hot vape. Truly warm, yes, but I never vape on anything beyond warm so,
for me, it's got much more to do with finding ultimate combinations of warmth, wetness, density, texture, and top notch flavor performance, as well as the speed of inhalation in cohort with the restrictiveness, the latter also being part determined by the speed of inhalation, and, I dislike throat hit to the point of only vaping with very limited amounts of throat hit. Also, wide open airflow is not for me, excepting only on an RBA that is a lot more restrictive than the vast majority of RBAs belonging in the realm of typical DTL vaping style.
All of the airflow has to smash right into the coils, and has to smash into them evenly balanced across the entire coil with not a lot of turbulence happening on the downwind side of the coil or else it just doesn't work for me in any way at all. But that's just me.
Hence my point. Most mech users (that I've seen) are looking for the lowest internal resistance and highest true CDR at whatever capacity they can get out of those two properites.
Assuming that's the case, the 30T is the best battery (for most users) for mechs that will accept 21700s. It has the lowest internal resistance (and sag) and highest amp rating of any battery we use, while providing good capacity.
Of course. There's no argument against that, as most mech users don't use multi-battery mechs, anyway in the first place, and, those who do aren't necessarily always interested in taming a hot build by choosing a battery that has a medium-low internal resistance that is similar to that of the Sony VTC5A as opposed to it having the absolute lowest of the low internal resistances. Obviously it's going to be a numbers game.
This is usually the part where you go on the defensive and start trying to prove yourself right and the other person wrong. There's no need to do that my friend.
I have not challenged anything you've said. I have no illusions. You have far more experience and knowledge than I do. I've only clarified why I said what I did.
Why would I want to go on the defensive side about that subject? I much prefer to make jokes. Like, one time I asked the shopkeeper, "Are you sure that mixing one bottle of 12mg and three bottles of 0mg gives 3mg? I think maybe you might be wrong." To which he replied, "Yea... it has been defined by science the fact that 12 divided by 4 equals 3 so splitting one bottle of 12mg across 4 bottles in total gives 3mg." What he didn't know was, the axioms define maths as a science, not the other way around so in the end he was still wrong. ?
But so k, I like this better
