    Then we would have to have adapters for the 'real men' that vape 1.5 ohms at high voltage.

    We have charts showing how high you can run various cartos on various high voltage mods. Why?

    Most just turn it up to see how high it goes, then complain that 15 watts is not enough.

    Advanced mods should go to at least 20 watts.

    Watt is a What anyway?

    There is a wide range of vapers. For some, an 18650 mod lasts 2 days between charges. For others, about 6 to 8 hours (I know one).
    A pair of little batteries last a heavy vaper maybe an hour or two even though people calim one or two days.
    That's why they are looking for the Li-ion cell with the highest mah rating, and why the Chinese lie about ratings.

    How long do a pair of 550 mah cells in a 6 volt stacked battery mod last? That's about 4 watt hours. I've seen 16340 cells advertised as having 1200mah. Those are the ones I want.

    ROFL Chinese battery suppliers never lie :unsure:
    I have some 600mAh 10440's, but my buddy says they taste more like 300mAh to him.

    Look, I inject humor from time to time (annoying to some) but this is, or could be a serious problem.
    Liabilities, education, Chinese lying about cell mah and protection, re-wrapping, and vendors following their claims are happening every day. Sure it would be interesting to know the exact model of each mod that blew but that would only start discussions about it being the cells, or user error. People would come here and post that they have been using the same mod, it hasn't blown up on me. Same thing for the cells except no matter what brand blew up, someone would claim it wouldn't have happened with AW cells, and if it did it was counterfeit AW cells. Others would just support the brand used.

    What we are hoping for, in the back of our minds, is that the mod or the cells, or the charger were not at fault, and it was only the user, ignorant of safe practices, that caused this. Then we could rest and not worry about making mods safer, or recommending cells matched to the application. It wouldn't be necessary. That's what we are hoping for, rght? We could get down to the business of educating the user. Then, of course, someone would come along and support the users.

    (slipped a little humor in between the lines :))

    The irony is that with a small bat like a 10440, mAh does effect taste because they can't produce the amps necessary to drive many of our atties/cartos properly.
    ex:
    fresh 10440 with out load .. 4.17v
    with 2ohm load ................ 3.48v
    So as you can see, the voltage had to drop significantly in order to produce amperage.
    You could up the C rating to get a better first few hits, but the bat would then spend more time on the charger than using it.

    You do bring up a very valid point. A new mod is new. An old mod is a degraded mod.
    Safety features can fail. If you have a dozen in a new mod, how many do you have in an old, used and abused, mod?
    Do you toss it when only 6 are left? How would you know? DO you wait until it won't vape anymore to sent it in for rework? or retire it? (or trade it off).

    As far as the eGo case, coating, and connections, there are plenty of old eGos still in operation. Is that a good thing, or a bad thing?
    How about chargers? How can you tell if the algorithm has leaked out of your charger? Monitoring perfomance is more than checking the label from time to time. Yup, still there, still the best one out there :)

    I'm looking into an eGo issue that may only get worse as the existing ones get older (watch for sales on old stock eGos). Something that Joye seems to have recognized and is releasing upgraded models with more protection, or so the ads claim.

    Kar,
    look this one over:

    So I find this thread now.For tube mods need some quality and safety specification:
    1. Use only protected batt`s
    2.Isolate inside tube with plastic, avoid batts to make contact with tube (except bottom for -)
    3.Make clean work without bad soldering and fix everything to avoid "broken wire"
    4.Use protected IC, or use PTC.
    5.Drill holes on bottom of tube for pressure

    This safety rules are enough to avoid any problem.

    I'd like to see this group decide to share the data you have ---

    I have a request. I would like many of you to write up --- all in one place and from your experience --- What every mod owner should know before buying a mod with emphasis on Safety and Care.

    The chatter about "they don't even know" is not really helpful. The actual data all in one place would be helpful.

    You each should do it -- not share notes --- and post here on a pre-arranged time. Wanna bet there will be different recommendations? Some will be in Latin and not accessible to anyone without a doctorate in chemistry with post doc in electronics. Others will be demanding with danger signs everywhere. Some might just tell readers simply what they have found to be most important with a bit of clarity on why it is so.

    I'm not looking for 100% agreement, and don't expect it.

    Please -- use your talents to help.

    And guess what --- some of us will read it --- and just might learn something. And, wouldn't it be nice to have a Sticky thread with that title? You never know -- someone might just read it!

    I, for one, really would love to see this-----and from this fiery group.

    tearose,
    as a verteran, with over a thousand posts, do you regularly meter your cells, charger and attys/cartos?

    You can spot all kinds of problems, sometimes before things go critical,with a meter.

    Your idea is great. I would put up something, but no one agrees with my views (sometimes not even me) :)

    Yup. Well, I do 2 out of 3. More diligently now than weeks ago. Haven't quite got the "meter the charger" part understood.

    But -- here's one for you--- Do you let your batteries set for at least an hour before and after charge before using them? Just read that one for the first time today in a thread far removed from battery data.

    Here's another? So what Do you do if it comes off the meter at 4.3----or even 3.9? Check your batteries is said 1000 times. Where is the data on what to do with the data? These are what Mod Owners need to know. I might have a good guess----but I don't feel qualified to answer that for anyone.


    Please do this guys/gals. a checklist of "things to do" or "things I do" could be helpful too.......with LINKS would be better.

    And no, I was never a School Teacher. It's a bit like a homework assignment, I know.

    Maybe a thread allowing one line tips. Then edited by the smartest person on the ECF staff into a top 100 tips (with links if required to supporting info), then made into a sticky. Could you imagine 100 long winded posts? Even I wouldn't read that (yes I would) :) But 100 lines, yeah maybe.

    BTW: if you ever ran into a cell that read 4.3 volts off the charger your meter is wrong
    or the charger almost blew up your battery. Thank goodness for the protection circuit on the battery.


    Here's my one tip (can be moved anywhere, just 99 to go):
    If you check your charger's termination voltage, regularly, and notice that charger voltage has changed, something has changed. Sameness gives you the warm and fuzzy. Change is not good.

    and since everyone links to Battery University, here's something a little different:

    A metal tube mod safety guide? Not too hard:

    1. Only metal tube mods using two batteries and with no electronics have a history of exploding, therefore the risk for any other type is lower. A lot less need to worry. One day, though, a metal tube mod with a single battery will explode, because that is Murphy's Law.

    2. If you would like to ensure your metal tube mod cannot explode, there are two ways to arrange this:
    a. Buy one that has a bunch of electronic protections, plus some gas vents and a blowout plug at the bottom, and hope the vendor is correct when he says it can't explode. The statistics say he is right because the blowups are probably limited to non-electronic control models. We don't have all the info though, some blowups we don't know the model involved (like the most recent one). And you have to trust statistics.
    b. Make sure there are large gas vent holes or slots in the metal body, plus some kind of a fuse. A mod with large holes in it cannot explode.

    2b is the easiest way to go as it's cheap and easy. Anyone with a drill press can fix it.

    There are other things that you can do such as fit an internal insulating sleeve (semi perforated), and ensure the batteries you buy have a provable supply chain.

    This is because part of the problem now is that many batteries are counterfeits. For example any AW battery bought through Alibaba is a counterfeit, and there will be plenty of those in circulation. At some point there will be more fake batteries in circulation than real ones, which is something to think about: you could be using a pair of junk reject re-covered cheap unprotected Li-ion batteries even though you paid $10 for AW ones. Maybe we are already at that point.

    It helps to be careful about the charging etc but if you have genuine safer-chemistry batteries it may not be vital. If the charger cooks them you just lose the batteries. If the charger cooks Li-ion cells you are in trouble.

    I can see what you're saying, but isn't this the job or responsibility of the supplier and people selling the mods to do this?
    Have it on their website. At the very least, have some sort of instructions or warning with the kit the sell. Besides that, everyone that vapes doesn't read or post here. I know people that vape that have never posted or read anything on this board.

    yep it is supplier responsibility to ensure by construction with every protection presented before.Only one safety measure need to be made by buyer, use only protected batt`s.

    Maybe a little more than just buying protected cells and vaping away.

    Somewhere between the little girl mini e-cig, and the real man's 6 volt stacked battery mod, some type of performance monitoring should be done. At risk goes up, so should the protective measures employed be the user go up. You can start off with a safe mod, a safe charger, and really good cells.

    Routine checking of charger/cell termination voltages, and discharge voltages. This will monitor cell life and possibly indicate a problem before it goes critical. Maybe even a written log next to your charger. If something changes, something has changed, change is not good.

    Maybe we should include a warning about recommending potentially dangerous things to a NOOB.
    Especially from NOOB to NOOB.

    I wonder how many will take up this real suggestion it picked up in another thread:
    "Oh and an extra 8 bucks over on xxxxxxxx they sell the bxxx extender...it allows you to use 18650's and stacked 3volts"
    No cautions, no warnings, just a NOOB to NOOB (N2N) recommendation to stack 3 volt cells.

    at least this N2N recommendation included AW IMR cells with his 20 watt stacked battery endorsement:
    " been vaping on The XXXX with 2 AW IMR 18490s and a LR DCT for weeks now. I'm really liking the step up from the Ego!:

    Yup, that's a step up for sure dude, from 7 watts to 20 :)

    or this N2N recommendation - - - - -

    or this other one - - - - -



    Sorry, I was wrong, it's not just N2N, it's everyone. Recommending a metal tube mod, extension and stacked batteries with NO warnings (except for the catchall tip about AW cells),
    "Now buy the extension so that you can run an 18650, 4.8V NiHm, or stack 2 AW Lifepo's to get some different voltages"


    Maybe a conscientious veteran can go find this post and offer some guidance about stacking cells.

    It`s good to inform people, i make this regular on ECF, but some people simple ignore our warnings.Anyway this safety problem tends to turn in drama :D.It`s can happen,nothing to say, but with ECF recommendation rules the danger it`s minimal, and for tube with that ventilation holes safety it`s done, pressure will be out :)
