If it hits like crap, I'd be considering replacing the 510, rewiring with heavier gauges, installing a better switch, and upgrading the battery sled/contacts, if you really wanna work on the mod and make it perform better. It's not a power-capability problem if it's not hitting well enough. It's probably a battery and conductivity issue. That's just voltage drop. Triple parallel gives you plenty of power through current... ...already more than 99% of people have a way to use without scorching something.
That, or just build lower (within reason) and make them more power efficient - less mass for the power they generate. Easiest way to compensate for sag. Might just be that your builds are too anemic, yanno?
12v unregulated is kind of insane, unless you have a 25mm or bigger RDA for dropping ultra-massive and intricate multi-wire builds in. Not to mention the huge risk should you have a short at that voltage. And this is coming from a guy who vapes dual series unregulated at 170w.
Lets look at the "max watts" for both. Triple-parallel gives you triple headroom, but lets leave a margin and assume 70A max (assuming switches/wiring are up to that) with 30A cells. Triple-series gives you 12v, but now you have a 30A limit.
A .06 gives you 260w at ~66A.
Going right up to 30A, a .4 gives you 360w in series.
So yes, series gives more power. The question is, can you do a build that works with that extra 100w? Do you have an atty that can handle that build? Even 260w presents some real challenges in the heat, airflow, and wicking departments.
I just don't see the benefit, unless you have a specific build in mind for it. No point in having it just to have it. Battery sag, maybe... ...but even 45A divided across 3 batteries shouldn't sag too badly. Or at least, you don't hear people complaining that it hits like shit!
There are regulated 200 watt plus mods out there that put out more than 12 volts. Done right unregulated is just as safe as regulated vaping.
Well, I agree that unregulated can be just as safe if you know what you're doing and you're running the right builds but...
As far as I know, no triple-series regulated mod (as most 200w mods are) GIVES the whole 12 volts. They take it to generate the power because that's the battery voltage, but they'll never give that much to the coil. The RX200 caps out a 9v output, so at most, they get a .4 up to 200w.
Regulated mods can also detect shorts, internal ones, even! A high-voltage short anywhere is significantly more potent. 12v will send 6 times more current down the line in the event of a short. If that doesn't immediately pop cells, I don't know what will... ...no getting lucky and catching the short right after firing. There's no denying the heightened risk-factor. Just because it's avoidable doesn't mean there isn't more inherent danger. You're just playing the same odds for higher stakes.
I don't see what the difference between wired and all-mechanical is in this situation. If anything, the wired one will just fail easier, but it won't be the voltage, it'll be the resulting current frying it.
Unless you're talking about quad-series mods I've never heard of, it's impossible for a 200w mod to give more than 12v. Even fresh batteries kick out significantly less under load and increasingly less as the charge depletes. Maybe quad para-series and a step-up converter? Quad series and buck-converter? Lipo packs? I don't know. Whatever it is would be pretty exotic.
I mean, correct me if I'm wrong. Not being contrary just for the sake of it - I'm an advocate for super high-power that's well-utilized and executed. All for 300w mods and quad para-series. I've just never heard of a regulated mod doing a true 200w+, let alone one that kicks out over 12v. Maybe some claim to. I'd be wary. You start hitting hard electrical limitations unless you're using so many batteries that you're essentially vaping on a bookend. Might as well hook it up to an AC/DC transformer and plug it into the wall.
I suppose it IS possible to get to say, 250w and maybe even higher. You either need 4 18650's (yes, 12v or 70A from 3 cells is just barely enough, but when the voltage drops under load, it isn't) or a really fat, high-current and high-voltage series/parallel lipo stack.
