Possible alternative we could push instead of FDA Regulations?

Aye, part of the reason we don't use them is the chemistry is much more volatile during a thermal runaway event.
They will vent and explode violently.

4.2V at .5Ω is still less than 9 amps.

Thank you mate.

I remember watching super_x_drifter's coiling videos on Youtube. He's a big Rea-only fan and in this video (on mech safety) he says his target build is 0.45R, which is 9.3A. Your 0.5R is pushing the bloody envelope of a 9A fuse :). I don't remember if he talked about the max for a Reo somewhere (sure he did since he promoted them heavily). Anyway that is why I thought they were fused well north of 9A.... (start at 14:30 on the vid).

If e-juice falls under FDA regulation, so does the delivery system. Pretty much like why a syringe is an FDA regulated product even though it may come empty.

Absolutely, you can forget about FDA accepting UL rating as certification. You can forget about doing a run around by calling the device something else.

FDA will put out a set of regulations regardless of who is in the office. May be stricter or looser depending on who. But the FDA will regulate. Nothing will change in that. Even the legislation passed gives FDA regulatory power over tobacco products as defined by the law.

I'm probably too low at the 9amp mark. I can't find the actual data (darn brain) but the NEW sub ohm spring can take up to about 12 or 13 amps. The V drop of the REO is still pretty substantial, so even a fully charged 4.1v is only pushing about 3.7-3.8 volts to the coil.
Obviously, the lower you go, the greater the V drop.
.4Ω-.5Ω is about as low as I'll go to keep a decent battery life and a bit of a safety margin. (international shipping starts at about $35...plus the cost of the new spring)

Cheers

Just out of curiosity I looked at their site but could not find a spec on that spring. If it's there you need a secret handshake to find it :). Do you have a link to your 9A spec?

Don't see a listing for a sub-ohm spring in their store either...

I've been scouring and googling and still have not found the actual data.
Great idea asking "over there".
Maybe I'll give Eric a ring tomorrow afternoon...I bet he has that data somewhere.

And I bet it is well north of 9A :)

Nothing wrong with that but I suspect it would not be a good idea to put a protected 18650 in there! (in terms of risk if one is not extremely careful and building for low power)

ETA: I find it "most peculiar" that that spec is not front and center. It's like "our device is fused but the fuse rating is a closely held secret". Very strange way of doing business.

Agreed. Protected batteries are not suitable for vaping.

The REO site depended upon Reo-ville to fill in the (huge) information gaps. (Rob was always close by to answer questions.)
I'm hopeful the new owner and a redesign of the site will change all that.

Fingers crossed

I follow ecig news stories and pay extra attention to reports of injury accidents. Basically all the reports involve carrying loose battereies with unprotected terminals or unregulated mods. It seems to be very rare that a mod with all the usual protections shorts a baattery. That should be no surprise. Phones and cordless power tool batteries are lithium ion and they rarely cause injury accidents realted to the battery..

Power tool batteries come in an enclosure frequently contains 18650s Those usually have built in protection in the battery pack.. Li ion can be many things as it's a catch all. Mods that use internal batteries use a Lipo. The reason those power tools and phones rarely fail is thanks to the protections built into the unit and tested to assure all is good with the actual battery being used. Even some replaceable laptop battery packs use 18650s, but again protections matched to the pack specs.

That's still no guarantee. Look at the Samsung Note 8, banned from everywhere and recalled. There's even been the rare iPhone that goes in someone's pocket. And there was a big Dell recall way back when due to battery pack issues. Anything that uses a Li battery, internal or not, can fail even without the user screwing up. But while other devices "hide" the battery from the user which helps limit user error, out stuff uses replaceable 18650 so the chance of user error resulting in failure is higher than other Li powered devices.

    The sensible answer is that FDA evaluation be voluntary. Many would prefer to use products evaluated for safety, but these must compete against an unfettered free market. There is no need to use force to make evaluated products the only ones available. I'm sure there are many out there that would start vaping if and only if there was a greater assurance of safety.

    Vaping is more than just a way to stop smoking, it is the ideal test for better ways of governing. The old compulsion-based model is especially inappropriate for it.

    In addition, all manufactures should be immediately allowed or encouraged to discuss the relative safety of their products compared to other vaping products. This is too important a subject to be restricted. Our government is making us less safe.

    Vaping is being covered for regulatory purposes by the TCA . There is no voluntary option in it, it's law. For the FDA to provide voluntary evaluation, it could not be under the TCA, or any other FDA umbrella short of legislation removing vaping from being covered by the TCA. And that's not happening.

    Besides, once you're talking voluntary, it's out of governmental hands and then you've got industry stuff like UL to establish standards. That's a voluntary pathway.

    Then there's no purpose for this thread. Yes Congress would most likely need to fix the law. They made it, that's their responsibility to fix it.

    I think you are wrong about only granting authority. Remember Tobacco product definition includes delivery devices.

    The Tobacco Control Act is located here.
    Family Smoking Prevention and Tobacco Control Act Table of Contents

    Reading Title III: Prevention of Illicit Trade in Tobacco Products seems to say they must regulate.

    Actually reading Section III seems to only indicate record keeping, a label, and making sure nothing is sold illegally. It says nothing about any specific regulations beyond that, everything else is at the FDA discretion.

    Family Smoking Prevention and Tobacco Control Act Table of Contents said:
    Section 301* Labeling, Recordkeeping, Records Inspection

    (use of statement "Sale only allowed in United States"; recordkeeping for tracking and tracing; illicit trade and illegal transactions)

    Section 302* Study and Report

    (study on cross-border trade)

    AND the illegal transactions are defined as:
    1. imported, exported, distributed, or offered for sale in interstate commerce by a person without paying duties or taxes required by law; or
    2. imported, exported, distributed, or diverted for possible illicit marketing, the manufacturer or distributor shall promptly notify the Attorney General and the Secretary of the Treasury of such knowledge.

    This thread got me thinking about that. But I think they do certify open system devices like flashlights, where a user can put any combination of bulb, battery and flashlight together into a system. I assume their standard is that any idiot may be putting that together, so the system needs to have enough protection to keep any idiot from blowing himself up.

    There are lots of mods that are conservatively rated, and have enough protection to keep any idiot from blowing themselves up. Power limiting, reverse polarity protection, short circuit protection, internal thermal protection make it really hard to blow up a modern regulated mod. Except...

    The problem of user selected batteries. Using 18650 as an example, there are a lot of different 18650 variants. It's hard to blow up an IMR/INR 186560 in a good mod. But people can put other non-recommended batteries in them and I'm not sure how UL would deal with that. And I suspect that is one reason you don't see power tool battery packs with user replaceable 18650's. and I'm sure the makers are happy with that since they can sell more overpriced battery packs without a competitor adding a greatly desired feature like user replaceable cells.

    A solution to that would be to make a new proprietary (to the vaping industry) battery format that would basically be an 18650 that is certified to work at the discharge rates required, that only fit vaping mods. It might also require newly designed recessed contact pins that are difficult to short out, like was done with DSLR camera systems.

    Build an idiot proof device, and the world will build a better idiot
