I had a Taifun clone start shorting out on me recently, and immediately afterward, i noticed that my batteries had little black fuzzy marks on them, presumably scorch marks. Are these fuckers even safe at all anymore? If not, i'm down to my last couple of crappy red Efests!

are they scorched or corroded (surface corrosion)?

If you have the ability to re-wrap...xacto the wrapper off and see if it's surface corrosion or if it's coming from the inside, if surface, polish off with some steel wool (be very careful NOT to short body to + with steel wool!!!!!!! [maybe even use non metal scotch brite for extra safety]) then re-wrap

Possibly that if the batteries get warm...moisture gets under wrapper, cools, then makes rust under the wrapper?

No, those burn marks appeared immediately after i shocked the shit out of myself with a shorted-out Taifun clone. I'm sure that's scorching.

That's a bummer. I'm gonna head to radio shack soon to pick up some shrink wrap since my dumb clumsy ass accidentally put a couple tiny nicks in two of my precious almost new VTC5's. Thankfully the local shop carries it, but the re wrap intimidates me.

I'd pick up some new ones, I'm no expert by any means, but that looks a bit troublesome, especially due to the circumstances which caused it. Good luck man.

Very hard decision.

I am freaking paranoid about battery safety.

Find a way to fix or scrap the Taifun for sure.

Likely I would be sending the batteries in for recycling.

Really interesting. Never seen this before! I have had atomizers short out to the tune of .01ohm and .05ohm before. Only instant excessive heat and mod hits the floor before any further damage is done. I have heard of folks being shocked though. Thanks for posting.

I've read some tutorials on wrapping them, but how hard is it to do? It kinda terrifies me, but I'm not ditching my VTC5's for a tiny nick, that can be re wrapped. I'll have to obtain a hair dryer. I know that.
It's simple and only takes a few minutes once you know how. Cut it to length or approx length. I use a heatgun which you can pick up on ebay for $10. Most have two heat settings which is useful. I used to wave a wind proof lighter over it lol. I also use the shrink wrap to seal off the ends of my lipo batteries as it keeps the wire connections safely in place. I learned from the video of this tutorial. I had a long look for the video but can only find his printed copy:

As for 'heat' , I gently wave the heatgun over it in the same way you might spray something. 'Evenly' is the key. It's amazing how quickly it shrinks - even with excessively oversized heatshrink. You don't need a great amount of heat to shrink wrap batteries or cover wires etc.

I'm actually not even sure if i was shocked or if it was just a massive sudden instantaneous flash of heat. It was fast, and the base of the Taifun was very, very warm - hot even. Other toppers would work fine but whatever i'd put under the 'fun would just singe me instantly when i fired it up. And that's two different batteries too. I'm pretty sure it's the dang center contact on the 'fun's 510. It's gotten janky and soft. It looks like the contact just screws down into a tightly coiled spring set into a delrin insulator. It's a clone. I haven't gotten any further than that.

I take it you've chucked the taifun Jeremy. Thing with clone tanks is sometimes the insulators are crappy, like they use silicon instead of delrin. Are you getting another Taifun or has it put you off them?

Thanks man. I will look over that, I've already looked over a few tutorials, I'm just always paranoid with all things batteries. One of them I don't even think made it through the wrap, and both batts have tiny nicks, but rather safe than sorry. My main concern is how the wrap will settle over the top and bottom. Both nicks are on the top edge. I'm guessing the heat just forms it into place?

Well, so long as you cut the wrap with some overlap, when applying the heat it kinda naturally just folds over and around the ends into shape. Will you take the original wrap off first? I would else you'll make the battery size thicker.


I have to go as its late here and I'm hungry for all things peanut butter related lol. But I'll check this again in the morning. And sorry if we half hijacked your thread jezzy babes :D

Gotcha, that's what I thought. I'm thinking I'm gonna leave the wrap on, since they are almost flawless, and my mods can definitely fit the extra wrap. I'll double check with electrical tape first, but they all have plenty of excess room in em. I'd rather leave it intact if I can, and I think it will work. I'm glad I can buy this stuff locally, gonna try to pick some up tomorrow.

Did you ever throw it on the ohm meter and see what it was shorting out to? 0.01 ohm or lower perhaps!? This is why I encourage folks to use the best batteries out there, regardless if they need high discharge for low ohm. If you short, or your regulated device glitches out, your much better off!! Sony's can burst to 150A+(safely) for short periods, no other battery out there claims anything over 35A or 40A burst rating. This is why I stick with Sony's!!

Serious question: how does an atty or a tank get *shorted out*? I've been having lingering issues since my Cana died and it seems like it took my Mega and Nautilus with it. Both of them display either Shorted or Check Atomizer on another perfectly working Cana, and displays NON on an MVP. I tried putting said tanks on yet another Cana and the ohms keep jumping or is way off - much like a few days before the first one died... :(

There are a number of things, and I'm no big expert on shorts but I know it can be caused by a bad or broken insulator/center pin, your coil touching the metal body or your atty, excessive gunk and junk on your coil and not tightening down your +/- connections well enough...There are probably more so I'll let others chime in.

There are many possibilities, and im sure i dont know them all. If your 510 pin is touching the outer area with the threading, positive 510, negative threading area, you will short. If your positive deck in a kayfun for instance twists and touches the negative, you will short. I just got two kayfun v3 blacks, and the adjustable 510 is too adjustable, it would back in, and make little contact, and that caused crazy ohm readings, all over the place. It reads non if the pin makes no contact.

Im sure there are more im not thinking of and dont know about, but those are some examples. I dont have experience with your tanks, so i cant say for sure on them. Hope that helps a bit, others will chime in, and correct me if im wrong.

@Sully gives great advice, i use way more battery than i need, why not? Also, if a mech doesnt fire after two presses tops, second one being quick, i always take it all apart and trouble shoot. Usually it needs some sort of atty adjustment.

Thanks @Sully & @TBCAmor! Sounds like your descriptions mostly apply to RxAs, correct? How about tanks like Kangers/Nautilus?
I mean, what im referring to is specific to the rbas and rdas i have, but the same could happen regarding positive touching negative on any tank id suppose. If your 510 pin touches the outer portion, it doesnt matter if its an rba or not. Also, if your pin isnt making good contact your ohms will fluctuate like crazy, and if the pin makes no contact it will be a short. So, it could happen with any atty id think, just in different ways.

A quick chime in before sleep. My 26650 TOBH kept giving me atty errors. Then I discovered the middle post screw was lose.. so I tightened it. Dumb thing was I checked everything else first and screwed it on half a dozen mods before realising it.

A short just means the positive and the negative cross someplace other than where they're intended (essentially, the whole reason why coils give off heat and light is because that's where positive and negative meet - but because it's a coil, it takes longer and has enough resistance to keep from causing serious issues... as long as you're not blasting energy at it for like a full minute straight; but even then, the coil would probably break down before the battery got too hot).

Yeah, that's a huge break point for many devices. In mine, the insulator is clearly just shot.

Thing with some tanks is the positive pin underneath is soo close to the negative. I've got a Kayfun like that. It's still been ok for months though. But every time I see it it's still unnerving.

They look right but you might take one of the stickers off. The LG's I have seen have a very light and kinda cheap looking printing on them. Think its dot matrix printing? They can be hard to read so it may be under the sticker.

I really hate when these vapor shops do not give you a pic of the tops and bottoms of the batteries.

FYI those batteries with the scorch marks could very well still be good if they charge and do not heat up while ya vape. I have seen the flashlight guys do much worse to the wrappers while doing full out discharge tests.

These IMR's we use are tough little buggers and kinda either work or they do not so you might set a charger by you and pop them in and just watch them and check for heat. Normal charging batts will get slightly warm but just periodically check for excess heat and see if they charge normal. If they charge super fast or super slow I would chuck them.

I have had a couple batts heat up like that and they turned out to be no worse for wear.

Still proudly flying the bright yellow flag here.

I is scared about batteries with scorch marks on them.

Gotta go now.

Something has been following me all day and is watching me from the closet.

Even worse, there is not a closet in this room.

Sony's come the same way. The info is under the sticker. I vaguely recall something about the labeling being required for import.

Just got some batteries in the mail today. They're supposed to be LG HE2's, but they've got a fat white sticker and no printing on the wrap. The sticker looks exactly like these: http://wholesale.longhornvapor.com/shop/lg-he2-18650-35amp-battery/

Are these legit?
I am charging my second pair I've Received this week of HE2's and mine have a clear sticker on them. It's covering the top line of lettering, but the second reads NO92DO22AG They are legit for sure, I've bought legit VTC5's from this guy before. If you want I could remove one of the stickers and get the top row of lettering for you.

They should have four posts attaching the positive contact, and are much sturdier feeling than the Sonys. Hope that helps.

They're in the charger now, but as i recall, it looked like there was a white (paper?) ring around the positive contact. That seems to line up with all the other pics i've seen of HE2's.

Yeah, it's a white, kinda light grey maybe, ring. Not sure it's paper, but sounds correct.

You ever figure out if your HE2's are legit? Also, how do you like em so far? I'm vaping on one of the ones I received yesterday, and it's going good. Will drain it to about 3.9 maybe more, then charge and hit the second new one.

Also, all four of mine have come at 3.6v, and taken a good 6 hours to charge on an i4. They speed up after a few cycles. They don't get warm at all really, one pair of VTC5's I have got almost hot on the first charge, but are fine now. Additionally, both pairs charged to 4.2, and were at 4.19 the next morning, but after a cycle they no longer lose a massive .01V, lol.

I'm definitely interested to see what you think of em. I'm pleased, and they seem on par with my Sony's for my builds. Also, I get two for about the price of one sony, and that's nice. Lmk your impressions once you put em through their paces, also would be curious of your build and atty, just to compare. I'm at 1.2 on kayfuns, and they seems to be almost identical in juice consumption as the Sony's.

So far i like it, but i've only had one charge cycle (they did get a little warm but not alarmingly so), and i'm still puffing away at 'em. I'm not a sub-ohmer though, so i don't really notice any performance increase if there is one. I just wanted a good strong battery and so far they seem pretty solid.

Coolness. I'm not really a dripper or sub ohmer myself, as I said, I'm a 1.2 ohm kayfun guy, so they more than fit my needs. I'm pleased with em, and glad you are as well.

1.2 ohm Kayfun here as well! Thinking about trying something a little closer to 1.8 actually.
Can't hurt to try, I don't like that high myself. When I switched to a larger diameter, the same 6 wraps on the 30 gauge I was using got me around 1.6-1.8, and it just wasn't warm or flavorful enough. Battery life improved, as did juice consumption, though. On a mech 1.2 just seems perfect.

Hey, they're rebuildables for a reason... 1.8 might be great for you, and or certain juices.

I have a kayfun that has the pin just barely below the threading, and it hasn't been an issue for the months I've had it, though it worries me, too. Last build I tried backing it out a tad, holding the deck in place obviously, but it just left the deck loose, so I have to leave it as is. I makes contact, just it's definitely on the edge.

@jeremy I hope you're digging the LG's. I really like em myself, they perform great for my builds, and it sounds yours as well, lol. My only issue now is I have 7 nice batteries all pretty new, so I have to be organized in my rotation. I'm obsessive with rotating through and not over discharging, and seven batts is a lot to shuffle around, though it's a good problem I suppose.

So... After some more use, you still digging em?

Oh, they're all dated, and numbered per each date of receipt and initial charge order, but I roll blue magic marker style, fine tip Sharpie to be specific ;) I might need to just number them all 1-7 in the order I have them in now, but they are all dated.

Can you do the same on a Nautilus or an Aerotank Mega? The pins are below the threading as well. :(

Don't have either nor have I used either, but you want the 510 pin to be a bit below the threading so it makes good contact with your device. Maybe our wording is backwards from eachother? I'm saying the 510 pin should protrude beyond the threading a bit. And again, I have no experience with those tanks, so somebody else will need to answer.

Yeah, they seem pretty solid. I've mostly only been vaping on my Taifun though, and i haven't rebuilt it since the other day, and it's maybe a little less than an ideal build. I think my cellucotton wick is too dense. I just started using that stuff too.
