First Reo Short, Coil Collapse. Cause?

[Hugga99]

Hi everyone!

i have had my Reo Grand for around 2 weeks. It has been awesome. I have been using a 1.2 ohm coil for a few days, no issues. I was using the grand tonight, and didn't notice any significant dropoff in vapor. Next thing I know, I feel a slight release in the device, and the coil had collapsed. I know from reading the forum that his means there was a short. It had been working fine moments before.

I know now it is possible the battery was weak, and I kept vaping. I didn't notice anything, but maybe I wasn't paying attention. I had also just taken quite a few consecutive vapes, very quickly. I don't know why I did, I was zoning out win Jimmy Fallon a bit, haha. Could that have overheated the battery? I have the Reo Grand vv too (thanks Harley), and the RM2 is working fine on it, without any alterations.

Any advice would be awesome. Is it ok to just re-stretch the coil, will it still work? Is the battery now garbage, I am charging it now and it seems fine, but want to make sure that it's not dangerous. Thanks!

Stretching out the spring will give you a connection, but you no longer have short protection, so it's definitely NOT advisable. Hopefully, you sacrificed the spring to save the battery, but check it and monitor it carefully.

I use a shortstop (nipple pointed down) between the battery and spring. In the event of a short, it will reset after about a minute, thus saving the spring replacement. I've been using this setup for well over a year with no problems, although I did lose one shortstop (it wouldn't reset).

Picture HERE.

Note that with this setup, there's still room for the spring to collapse if the shortstop fails.

That looks like a great idea. I think I will get one of those. Would that work in any mechanical mod, cylindrical, etc? It looks small, can you still use the regular 18650 with it?

Do you think I just overused the battery? Seems like the cause to me. Should I still order a new spring even with the short stop? I just recharged the battery, and it seems fine. What specifically should I look out for, getting too hot?

Yes, you should replace the spring. Besides the safety factor, there is a definite difference in performance between a spent spring and one that is in tact. You'll want to replace it just for that alone.

Ok, awesome. Thanks for letting me know. Before the spring arrives, will it be safe to use as long as I make sure to not overuse the battery?

A battery drained to under voltage cannot cause a spring collapse. The only thing that can do that is a dead short. You haven't said what you are using on the Reo yet, but if it's a Reomizer you had best double and triple check your coil for loose screws and insufficiently trimmed coil wire that could be causing an intermittent problem.

Others have without issue, but I never recommend it.

It's not advisable to use it with a stretched out collapsed spring because you no longer have any short protection. It's just not as safe. Since you have another REO anyway, why not just order a couple of new springs and wait on them. It's the safest thing to do.

Yea, that is what I will do. I am using a Reomizer, I put it on the Grande VV right away, after the spring collapsed, and it worked straight away. I then rechecked the screws, the spring was perfectly centered the whole time, and checked for debris. I lengthened the coil and fired it a few times with a fresh battery, worked fine. I'm not going to use it again until the new spring, still.

Could taking many consecutive hits cause a short, or am I missing something? I am very careful when building the RM2, so I knew that wasn't it straight away. If overusing a battery cannot cause it, then the only thing I can think of is the fact that I took MANY consecutive hits, which I had never done before.

 

[Rickajho]

What are you using to check the resistance of your builds? It could be that the coil is lower in resistance than you think it is.

Also,
what voltage did the battery read when you put it on charge after the short ?

 

[Filthy-Beast]

you said it was after several long chain hits. What ohm is your coil? I think you might not have short. But were running to low an ohm coil, pulling to many amps through the battery and your chain hits heated the spring to the point it collapsed

My thoughts as well shorts dont generally happen when you casually vaping .

Were you using a metal drip tip?

Some metal drip tips can go too far into the chamber when inserted and make contact with the positive post, or snipped wire on the back of the post if you bent it up.

Sometimes drip tips have some "play" to them, and it wasn't making contact until you nudged it the right way while vaping to finally make a connection and cause the short. Could be why it happened out of the blue...

The VV REOs take 2 18350 batteries, not one 18650....maybe that could be the cause?


eta- never mind, I see now that you're talking about your Grand. Still working on first cup of coffee

Like others have said, only a hard short. The screws touching a metal drip tip, the coil touching the cap..... It has to be something about the coil or wire touching something it's not supposed to touch. Or what battery are you using? Possible short in the battery, bad battery? Just throwing things out there. Definitely not from vaping too much.

Long short, but it happened to someone a few months ago. They got some pocket lint with a piece of chewing gum wrapper foil in it into the RM2. the small piece of foil would shift and cause a spring to drop intermittently. I think they went through three springs before they found it.

Just to let you know the spring is a spring not a coil. THe spring is below the negative end of the battery. THe coil is the wire inside you atty. I had to reread your thread several times for figure out what your problem was. Sometimes it gets confusing. No big deal. I just thought it might help in trouble shooting your problem.

I Have to agree with Filthy on this one. THe atty works well on your VV but didn't on your Grand. What ohm is your coil and what type of battery was in the Grand?

 

[ancient puffer]

Nothing to add as to possible cause of the short,but as for the shortstop, yes, it works with AW IMR 18650's, both the 1600 mAH and the 2000 mAH (slightly longer).

Slow collapse of the spring due to over heating, as mentioned above, seems very likely. Best advice is to use AW IMR batteries, and get an accurate resistance reading (ohms) on your coil. I would strongly advise anyone who isn't knowledgeable about such things to stay at or above 1.0 ohms. I don't recall seeing anyone selling atomizers lower than that, and its likely because of the risks associated with sub ohm atomizers. You can drive most any automobile safely at 50 mph, 150 mph is a different story.

What are you using to check the resistance of your builds? It could be that the coil is lower in resistance than you think it is.

I used my MVP2 first, read 1.1-1.2, then double checked on my Provari, read 1.1. I am pretty confident it is accurate. I have used someone Ohm meter before, to check the accuracy of the MVP2, and the MVP seem quite accurate +-.1
