    Well, that's good that you at least remember to check the resistance. This is a *must do* in my opinion. What resistance is this coil you are having problems with reading at?

    As for the unsatisfactory results? I'm not sure because there is a LOT of variance in how someone builds a coil for an RBA... two are unlikely to ever be *exactly* the same... but I doubt it has much to do with it just being 28 gauge wire. If in doubt source some new wire, maybe a lighter gauge like 30 and try that. Maybe there IS something wrong with that specific wire you have... You didn't tell us... have you built a coil using that exact same wire that worked well?

    What are you using for wick?

    No, lots of people use 28 gauge kanthal in the AGAs. How many work? Depends on the builder.

    I think you only need like five posts (maybe 15?) to post elsewhere... You really need to take this to the RBA sections I think...

    I may be off base, but you're almost doubling your amps going from 32ga 2 ohm to 28ga 1 and sub-1 ohm coils. The gauge of the wire is really irrelevant. You could benefit with a few things. 1 being MNKE batteries, since they have a 20amp rating, not the 10amp of eFest and AW IMR's. Also, try the 1 ohm unstacked. Stacked it's 70.56 watts, but unstacked it's only 17.64. Maybe even try lower with an unstacked setup. I'm running a .5 dual setup in my Nimbus on my EA Mod, and it get's a little warm when I chain vape, but not hot. IF it's of interest, it's also 3.5mm silica wick w/.5 ribbon wire. I plan on replacing all that with 500mesh stinger wicks soon, so it'll be virtually bulletproof. As for the 1 ohm unstacked, I have a 1ohm in my iHy standard, .5 ribbon 2/3 wrap, and it's ripping the plumes out. More batts/voltage seems like just more problems to me...just MHO, tho.

    Oh, sorry..I have an AGA, too. It's currently a 1ohm 3/4 wrap 30ga on a K100 w/eFest 18650 and it vapes like a beast, now that I bored the drawhole out to 1.2mm. The wick is whatever junk that was in the pack. I'll replace that with 500 if it ever goes bad. Juice is 70/30 vg/pg and it's only a hollow half-wick, since whole ones are virtual overkill.
    So yeah...Aga, unstacked, 1 ohm, 30ga, bored out...vapes like a pro.

    I've used this wire a multitude of times building coils, most of the time it fails because of the resistance created. It's just way too low, either burns up all my juice instantly or just gets a nasty burnt taste. I'm using a 500 unoxidized mesh wick. I've made over 50+ wicks and coils, but always have problems with .28 gauge. It just gets to damn hot. I've had the most success with unoxidized wick.

    I get all my rebuildable supplies from Vaporizers, Ecigs and Accessories (edit. Dunno ... this is, but steam monkey is where i get my stuff)

    The only reason I mention my Aga-t2 is that when I switched to my Adam, I noticed a huge difference in connection, connectivity, power, etc from the quality of metals being used. I could put the same atty on my VV mod at 5.5v and my adam will still produce more vapor with longer battery life. It's just better build better materials. I'm wondering if this could be the case with my Aga

    TBH I really have no idea what your talking about as I have never stacked batteries in my life nor will I ever. I'm not an electrician and ecigs is about as far as my electrical knowledge goes, but you don't have to be a guru of electricity to know stacking batteries on an unregulated mod is extremely stupid. Your setup sounds interesting and Im curous about the vape.

    Thanks for all the input.

    I think I trust Steam Monkey... did you get the AGA from him too?

    BTW, you should now have a high enough post count to post in the RBA forums, if you haven't already

    Interesting... I have never heard of your problem before. But as far as i know, people have used 28awg on mechs without any problem.

    Perhaps the wick and wire setup is too close to the deck? But if only the switch and bottom gets hot, or at least they get hot first of all, then there may be something wrong with the battery or/and some kind of resistance in the switch... Im no expert, just speculating.

    Either way, good luck with it.

    So I have an Adam mod with an Aga-t2 and whenever I put .28 gauge coils on it, it fires but it straigh up melts my battery and mod. The coils light evenly and cape extremely well. But after 10-15 seconds my switch gets super hot and my bottom cap does as well.

    I throw some .32 gauge on there and it doesn't cape as well and takes way more time to rid the hotspots but it doesn't melt my ..... I'm bummed man, I see everyone using .28 on their genesis.

    .28 gauge: .8-1.1 resistance
    .32 gauge: 1.8-2.2 resistance


    thanks
    Assuming your push 5 volts

    5 times 5 is 25 divided by 1.1 om

    Your pushing 22.72 watts of power or more.. Hence.. hot, hot

    Ok cool I will do that later tonight after I'm off work and when I have time to tinker with it. I love steam monkey and I trust them completely. I got my Aga when they first hit the market I believe in like sept or nov? I can't remember but they were hard to find. I got it from a site called mountainoakvapors which I also trust highly. I've spent hundreds there but I think I just might invest in a brand name genesis atty. Chinese clones always skimp on material quality. You need highly conductive contacts, like brass or copper for the center post and ground.

    I know once I get the .28 gauge down my genesis will top my Oddy in terms of vapor production. As of now theyre just way to finicky. It will be firing amazing one night. Take the battery out put it in the charger and go to sleep, wake up and fire it and it's nothing like it was the night before. Extremely frustrating.

    Is the Adam new? I've had some issues with brass contacts being pretty corroded and it'll get hot to the point where you think you have a short. Maybe try cleaning the brass contacts. It'll fix it right up if that's the problem. The lower resistance will amplify the problem so maybe that's why you're not getting it with the 32 gauge.
