    ideally i would like to purchase 2 18650 and 4 18350. To try it all out myself.

    Also what are the pros and cons of both configurations?

    TIA
    Single battery verses stacked batteries.

    18650 induces the boost cuircuit. The mod pulses at 6v peaks. You have 1v of run time, 4.2-3.2 cut off. You get best performance for power and longevity above 2.3 ohms up to 15w. 2.4 ohms @ 15w 2.5amps limit. Below 2.3 ohms you start to lose power as it eclipses the amp limit and the batteries run down faster.

    Stacked batteries induce the buck circuit, which is much more efficient. The mod pulses at 7v peaks. You have 2v of run time 8.4-6.4 cut off. Stacked are best for longevity as they will last 2-3 times longer than a single battery no matter the ohms. Stacked are good for maximum power down to 1.3 ohms . Highest power achieved with 1.5 ohms at 6v for ~ 24w at 4 amps

    You may find the stacked configuration needs to be set a little lower on the power setting to match what your used to in single mode, due to its higher capability and output.

    I have two blogs on power and stacked batteries.

    Why stack, stacked 18350, stacked better

    "but a microtorch works best ($15 at Home Depot)"
    No doubt, and you can solder with it as well !

    FDA regulates those chemicals as food additives. You might swallow a bit, even sniff some, inhale a bit but not intentionally inhale them all day long. Looks like the safety of most of them was determined 20+ years ago and they don't actually test/study them unless theres a problem. The butter-flavor diacetyl mess was over 10 years ago and FDA didn't even get involved. It's been banned essentially by insurance companies and theres 100 million dollars in lawsuit awards from that - but FDA still lists it as 'generally regarded as safe' status and fairly recently reviewed the evidence and decided there was insufficient evidence to recall that " GRAS" status.

    So, basically don't take any comfort that FDA certifies anything.

    Their regulation for food additives/flavors is basically keep records of where you got it and what you put into and keep the records for 3 years. They inspect a representative sampling of businesses and check that their recordkeeping is up to snuff. They seem more interested in your label yet the flavors just show up as 'natural and artificial flavors' on the label.

    It looks like for tobacco products its similar but you put it into a website - usp PG 40%, usp VG 40%, TFA banana 7%, capella chocolate dark 6%, TFA coconut extra 4%, distilled water 3%. Seems like no big deal but for the HPHS it sounds like a whole battery of lab tests - how much of each of about 60 tobacco toxins and carxinogens - ejuice should have some different list and really if they have records internally of what chemcals are in each of those flavors then they should be able to calculate the HPHS instead of requiring tests -not that i expect they'll actually do anything useful with the data.

    Custom natural flavors could be sticky as the precise makeup is unknown, and tobacco extracts ought to be especially as they have those tobacco chems to some degree and that degree can vary a lot depending on how they're extracted.

    This sounds delicious but there is no chocolate cream listed at buyhangsen. Where did you get yours?

    It occurs to me that I never explained the real reason why I wick the coil with cotton prior to installing in the head.

    A 2mm coil is large enough to hold an amount of cotton that nicely fills the channels but a 2 mm micro screwdriver (5/64 drill bit) does not fit down in the channel to hold the coil in place while installing the grommet and pin. So I wick and use the cotton to hold the coil in place.

    One could make the coil then hold it in place with a smaller bit or tool, however when I've tried this the hard tool would deform the coil and not hold it in place as well when trying to install the pin.

    Nice post.
    US (I assume your referring to an Ultra Sonic here).
    Not sure what UC is. Are sold based on their wattage ratting. I use a 100 watt unit. To clean my auto parts. I have tried it for steeping and was not convinced it was as good as using a Microwave.

    Next I got obsessed with the topic. After all we are not doing anything new here. Grandma made pickels right. India is famous for its pickells.
    What are you trying to achieve in a pickle ?
    You have oil you have the item being pickled and you have the masala or spices.

    How did Grandma do it ?. Talk to her.
    And you will get your answer.
    Hint it involves direct exposure to sunlight.
    So I just dont add my nic till the liquid is steeped then I add the nic. Nic only takes 2-3 days to infuse into a juice.

    Thanks, LaraC. I'm glad you found use in my posts to help formulate your own comments.

    In my view, the only way we can win this thing is if we demonstrate to FDA that there are too many well-informed and politically active vapers to ignore; vapers who can see straight thru their BS and will not stand idly by and let FDA impose arbitrary and capricious rules based on conflicted and junk science, misinformation and conjecture.

    DrMA, you are doing a wonderful job commenting to FDA. Absolutely wonderful!

    I've sent in two comments to FDA now...one with quite a bit of your "capricious and arbitrary" copy/pasted.

    The second I sent was a great deal of the "Conclusion" in Hajek et al's review of benefit/harm. I was happy to see that you've also used that study's ammunition. Your comments are extremely professional in tone and content. A pleasure to read, as are your ECF posts.

    I'm cynical enough about the economic factors at play (BT, BP, tax seeking governments) to think nothing rational or truly science based can possibly stop the juggernaut. But at least everyone who comments against the deeming proposals for e-cigs will have tried.

    Thanks for what you're doing.

    I have tried this on 2 of my Kayfuns and have litterally fogged up my house trying to get a dry hit...not happening! LOVE IT! Funny though I haven't been able to find anything like this anywhere else..even on Youtube except with silica. You should really post a video.
