Regulated mods ohm threshold

[Nightshard]

The protection circuit in regulated mods is actually a good thing.

Putting a battery backwards is silly but could happen, over draining is possible and short circuit protection is a must.
BUT the 1.2-1.3 ohm threshold in most regulated mods is too high in my opinion.
Why so high? By my calculations if you run a mod as high as 15W at 1.2 ohms you only output 3.5 amps and that's well below the maximum output of even a 18350 IMR.

I'm not sub ohming but lets say i made a coil a bit above the limit, put it in my atty, then when it heats up/get used a bit, it drops to 1.1, that's really annoying.

It would have been nice if the ohm threshold could have been a setting in the mod at the range of 0.6 - 1.2 (to be on the safe side).

I think the AMP limits of the mod are mostly about protecting the electronics. Pushing high amps through a safe battery and a contact is fine, but most circuit boards have some sort of limit. If you pushed 15A through a small circuit board like on most regulated mods, you would burn it out.

Someone correct me if I am wrong. This is all from Digital Electronics in highschool.

Not all regulated mods cap out at 15W. (Tho, for the sake of argument, many do, or lower)

My itaste VV3 will fire a .8ohm single coil. It is 5v/11W max, and I think 3.5amp limited.

You will not get what you want out of it, but it will test the ohm's, and light that coil up for you. The entire time it is in limp mode and most likely reeling back whatever voltage it can to baby fire it and protect itself.

It does not have enough oomph to light dual coils in the 1-.8ohm range. In fact, it weakly lights 1.2ohm stuff. (dual) Move it up to about 1.5ohm's and it is back in it's happier place and will light them up no problem, nice and quick, nice and hot. It will light a 1ish ohm single coil right up. You aren't getting quite the same strength - as say a full charge from an unregulated device / battery. But it's still potent enough to work. (fairly well) I'd imagine this does increase the strain on the battery and circuitry in the unit so I use it to test, that's it.

DNA 20 and DNA 30 chips and set ups can handle up to 20 or 30 watts. And honestly after playing around in the lower 20's wattage wise, I can't see me needing 30W - unless I haven't met the atomizer that I need to hit that hard to get what I want out of it.

Atty's with a chimney, and small chamber 22-25W is really pushing it. (to me)

But the 15W ceiling on a lot of the regulated stuff floating around right now is unimpressive IMO. (Agree) It is a byproduct of what Acid mentions above. The electronics have limits. And with a mech, you remove all that.

I don't agree with with the conclusion that electronics can't handle it.
The kick 2 for example can go down to 0.5 ohms and when you put it in a mech, it is a piece of electronics in a confined steel tube, just like in a normal regulated mod.
So i guess it's all about the quality of these circuits.

8.4A certainly wouldn't be a problem for most circuit boards, although the heat might have some effects. I'm sure most APV's could easily handle it for a while.

But also keep in mind that with warranties in place, they have to replace any parts that fail. So if they were to unrestrict them, and the heat killed the board, they would be liable to replace it. Maybe that has something to do with it. There has to be some sort of electronic safeguard in place, and since lots of the regulated mods end up in the hands of...lets say inexperienced vapers... the companies want to play it safe so that they don't have to replace too many of them.

I guess we could think about it like various grades of chain. You can buy chain that is rated at 5 tons, but it would probably work for 8 tons and never fail. But they don't tell you that it is safe to use at 8 tons.

Would a VTR work forever at 10A? Probably. But if even one failed at 8A during testing, then they will rate it lower than that.

Food for thought and all that.
