New member. Need help with Stingray

[Moaufan]

Welcome to the ECF family. It's a great group with a lot of great information!!

I cannot express deeply enough how important battery safety is. 0.1 build? Do you even know what batteries your running in your mod? I haven't been using mech mods for a very long time, and I was like you 3 months ago. A feeling of just overall excitement, that was until I posted a thread on here about my old nemesis kept shocking my hand and well...Everyone on here pretty much told me I'm fecking ......ed and need to stop what I'm doing and read/learn all about battery safety. People were a little mean, but it's tough love because no one wants to see anybody get hurt by a battery exploding in their face.

I would tear out that build right now, and build something a little closer to 1ohm for now. I do vape subohm myself and I like a build around .5-.6, but I usually keep my builds around 1.2 ohm dualcoil.

There is also this link to check out about batteries and their safe zones.

You will need to either download it and open it in Microsoft Excel or Google Sheets for proper formatting.

Please be safe.

The batteries she has are Orbtronix SX30. 18650 IMR 3.7V 2100mAh 30amp.

Why do you guys think the Stingray is crap? Besides it missing that bottom piece, there's nothing wrong with it. How do you know a battery vented in it? The inside is clean. The guy at the shop didn't do the build, I did.

I haven't had time to read all of those links, so I got one of those Ohm's law apps, plugged in the voltage and amperage ratings of the batteries, saw the resistance number and aimed to build above that.

So if I'm doing this right, the absolute lowest resistance I can safely do is 0.123 ohms? I know it's best to stay away from that number. But I don't need to be at like 1.8, right? I did a 0.61ohm build. It's not hitting like used to, but I do feel a lot better about it.

For the Panzer, I went to 0.26ohms. I'm using those purple Efest batteries on it (18650 35amp 3.7V).

I do appreciate everyone's input by the way.

Not to beat a dead horse, but;

The stinray shouldn't be used for several reasons,
1) at no time should it get hot enough to burn the user, as in ever. This is the first & most important clue that something about the build, battery, switch, tube, connections is unsafe for use. Warm after use - okay, hot enough to burn or be uncomfortable to touch / hold - never okay.
2) the lock ring has been removed, this prevents accidental / unintentional firing and exposes pieces to damage or contact with conductive materials.
3) it appears the firing mechanism has been unsafely modified, damaged or replaced with cobbled together pieces with necessary parts missing.
4) he may have called it patina but from your pictures it appears the body has been exposed to extreme heat more than likely caused by electrical means due to repetitive unsafe use, which would explain the fubared and or replaced / hacked together bottom cap/switch.
5) The previous owner obviously ignores or has no clue about mechanicals and vaping safety or this tube wouldn't have been in use in the first place, and dang sure would not have been sold in its condition, especially to someone fairly new to mechanicals.

The battery she is using (orbtronix) is a good battery if it is authentic, there are many re wrapped lesser quality batteries on the market. I wouldn't trust anything bought from the place you got the stingray from, not even a toothpic.
The battery you're using (efest) is a re wrapped 20 amp continuous rating confirmed by independent testing. Staying below it's continuous 20 amp discharge rate is the only safe way to use it.

Your build on the panzer is 4.2v / .26 = 16.1538a & 67.8461w is that safe?, yes & no, depends on your experience with mechanicals/re buildables and the accuracy of the ohm meter you're using.

There are no set industry standards for how the batteries we use are tested and rated, in other words there are companies that buy 20 amp batteries and re wrap them as 35 amp. The problem is some times worse, a few of them slap a 20 ~ 35 amp wrapper on 10 amp or less batteries. (ebay, amazon, store brand, etc)
Buying from a reputable source is the only insurance there is.

Currently there are no 18650 batteries that have a continuous discharge rating greater than 30 amps on the market.
Taking head room for safety into consideration .2 ohm is as low as a top quality authentic battery can be used safely.
.2 of an ohm (two tenths away from dead short) is not a mark that folks new to mechanicals/ re buildables should aim for.

Sure some folks go lower, the smart ones know the risks & can recognize the signs of danger immediately, they have the equipment, experience and knowledge to know what to do to reduce risks and know how to handle the situation when shtuff goes wrong, just in case.

Sub ohm vaping with mechanicals & re buildables is designed & intended for use by advanced / experienced vapers, nothing at all wrong with new folks using them IF they have the necessary equipment & read, learn, understand and follow sound safety practices and don't rush in.
If safety is a priority there are no short cuts.

No one is trying to spoil your fun, ruin your vape experience or be a wet blanket although a wet blanket and a safe place to toss it may come in handy if the stingray is used in its current condition.

I'd be past irritated with someone that sold a mechanical for my wife to use in that condition without first explaining that it shouldn't be used before it is repaired. way past.
His size & agility would be the determining factor in the location of the insertion..

On the assumption that tex-smoke. com is the shop's Internet presence, it appears that they specialize in janky.

So what build did you end up with and what battery are you using in your mod?

Running a ~.3 ohm (I have not checked it but I trust the builder with my life) dual of 24 or 26 in my Patriot. Finish matches better than the Tobh did (shiny with shiny, vs brushed with shiny).

As for batteries, either VTC5 or VTC4 for backup. Only reason I have the 4's is cause my b&m ran out of 5's and I wanted more backup batteries.

You still need your own ohm reader, since the ohm reader your builder used could be off and your coil resistance can change at anytime, from the the slightest moving of the coil or if your post screws become lose and you readjust your coil before tightening or after rewicking, also will let you know if you have a short.

Batteries: The VTC5 does have more mah than the VTC4, but I don't think most people realize that the VTC4 performs better and will give you a more consistent vape longer than the VTC5 even though the battery won't last as long.

Thanks for the heads up on 4 vs 5. Thanks a freakin lot. Now my bank account is going to suffer thanks to you.

It doesn't have to suffer, I have 8 VTC5s and no VTC4s, because I need the mah more and I carry enough batteries with me as it is.

5-5's, 2-4's, a dented 5 thanks to k-100, then a handful of misc batteries that don't leave my desk; are what make up my collection.

Sounds like you have enough batteries.

I guess more batteries than devices is a decent place to be.

Yup, I always carry extra batteries with me always need backups, and rotation.

I just now found this thread and read every post.

I'm presently feeling sick in my stomach along with a headache from the anger I have to towards the original sales person who sold those mods to the original poster. This crap is really, really getting out of hand. I wish that I had an answer, but I got nothing. I'm speechless.

I kinda wondered where you were.
Absolutely mind boggling, isn't it?

Unfortunately, it's probably going to get worse before it gets better. There are unscrupulous people out there and then there are the vape shops who have owners and employees who are not as educated as they should be. Clueless, you might say.

And then there are guys like this. 24g 10 x twisted 3 wraps dual coil. Vents at end This one had me speechless. I don't know how many of us reported his videos to YouTube -- possibly 100 or more? Unfortunately, the videos are still out there.

I believe it may take one or two incidents where there is some major bodily injury and a lawsuit against a vendor from an exploding mod before something changes. It's not what we need from a media perspective, but to protect human beings from vendor negligence it appears to be an unfortunate necessity.

 

[insaneredrooster]

There's absolutely nothing wrong with the stingray. Even if it did have a battery vent in it, which I still doubt because of how clean the inside is. I even fabbed up a working locking mechanism for it.

 

[Kaezziel]

Definitely an improvement!!

Now, what'd ya do about them coils? Still running under 0.1 ohms or have you rebuilt to a reasonable resistance level yet?

 

[insaneredrooster]

My panzer was at .26 but went up to like .4 and wasn't doing well at all in the cloud-producing field. I did five wraps triple parallel dual coils 28awg. Puts me at .16 ohms. I'm not going under .1. This setup gives me a really nice, smooth and cool hit with a good amount of vapor.

The stingray I believe is at .37 ohms. Double parallel dual coil 28awg. No part of any of our mods gets too hot.
