Atmizoo Dingo can't handle the heat? RBA problem

[ZTKT]

Forgive me if this thread is redundant or the answer I'm looking for has been answered elsewhere.

I have recently picked up a Atmizoo Dingo and previous to purchasing the owner disclaimed that the Dingo can't handle low ohm coils. I of course inquired why and he continued to explain that sub ohm coils on any RBA will heat up the device to where it is uncomfortable to hold.

Truth be told the Dingo could not handle my dual coil Trident RBA [EDIT: [Each coil] at ~.8ohms], instantly becoming to hot to hold.

Although, the Dingo is capable of handling my IGO-L RBA with a single .8ohm coil.

Could someone please explain to me why the Atmizoo Dingo can't handle low ohm coils?
My other Mechanical Mods [ie. k100, Sentinel, Titan] can handle sub ohms no problem.

While we're discussing the Dingo...Dingo/Roller owners what setups do you have with your dingos/rollers??

Thanks!

Can't answer the first part but I love me my Kayfun Beta on the Roller SS-IM

Is it a .08 ohm dual coil setup or is each coil 0.8 ohms?

Instant hot means a short usually. It's an 18350 battery, you may not want to push it so hard.

Is it a .08 ohm dual coil setup or is each coil 0.8 ohms?

Each coil is .8ohms, so 2x .8ohm coils.
Sorry, I don't know all the equations to provide the total resistance.

Edit: Did some quick research and if I'm correct my dual coil of .8ohms on each coil is a total resistance of .4ohms?

Still don't know why the Dingo can't handle it while other mechs can.

Two .8 ohm coils would give you .4ohm resistance.

I am not a dual coil expert but wouldn't 2x 0.8hm coils be 0.4ohms. Either way a single 0.8ohm coil is around 5 amps, an AW 18350 is rated for 6 amps (by the guy who sells them) so I would think the draw you are putting on it with that dual coil setup is too much. I believe that is around 10 amps as you have it set up if you plug in a fully charged battery.

I can't answer your roller question but I wouldn't run that on an 18350. As far as I know, and someone correct me if I am wrong, you want two 1.6ohm coils for your 0.8ohm dual coil setup.

 

[Fury83]

And hopefully you are using an AW IMR for this experience.

Assuming you have a .4 ohm dual coil at 3.7v you'd be at 9.25 amps. If you vaped it on a mechanical with no voltage regulation and were at a peak of 4.2v you'd be over 10 amps. On a 18350 you're experimenting in dangerous territory.

You are correct based on my quick research ohm/amp wise!
Thank you for all the info. The 18350 batts I'm using are EFEST IMR 800mah 3.7v

The battery science definitely makes perfect sense and happy you've brought this to my attention.
I take it I was engaging in dangerous vaping.

I appreciate the feedback and knowledge!
I better do more research so I don't risk any accidents.

Thank you!

I second what was said above. The 18350 battery is too small to push those amps, you may be gambling with exploding batts. For extreme sub ohm coils you really want to use MNKE 18650s they have a 20 amp C rating.

If nothing else, just make sure you understand what is going on in each part of the vaping equation. Especially when venturing sub-ohm on an unregulated and unprotected device. Also, you can use a shortstop or vapesafe fuse. They usually trip around 6 amps.

Also, I know some people like efest imr's but I don't really trust them enough to push them. I have had several different efest batteries of the same size, mah and top that are actually different batteries with an efest sticker on them, so maybe one is good and the other is not quite as good, I don't know or want to find out when running something drawing a lot. Also, I pulled the sticker off a couple and they were the same batteries with the same markings that were sold for a few bucks cheaper as unlabeled IMR's. So I just pony up the extra dollar or two for AW's for anything under 18650.

Personally, I'd never push an 18350 that hard. .4 ohms is asking for battery failure.
I run my Roller at .8 - .9 ohms with a single coil, with either 18490 or 18650 batteries.

It's pretty easy to explain how to do these calculations for any battery in a pretty short post, and a full thread could include calculations for common batteries. This info should be stickied.

I haven't been around this forum that long, but this particular topic seems to come up a lot, and it concerns me. I really wonder how many of these "working" setups are actually unsafe for the batteries people are using to push them. This can bite you in the .... even as an experienced user when you mindlessly swap the SLR setup you're running on your 18650 mod onto the top of your 18350 travel mod on your way out the door.

I sincerely appreciate ALL the advice, info, and feedback provided by all of you here!

Efest batteries were sold to me at a Local Vape Shop with my Provari when initially purchased, but it is most definitely apparent that AW are the way to go for any mod, vv or mech.

Starting with this thread I will avoid using 18350 and EFEST for my SLR set ups.
I do own a couple AW 18650s and will exclusively use those from now on.

Again thank you everyone!

I hope others too will benefit from this thread.

 

[Fury83]

Just to clarify, efests aren't bad, I just don't know if they consistent so I personally am more comfortable with something that has a longer track record.

And good luck with your setups!

I've been using a few Efests lately. I have some mixed in with my AWs. I see no difference in performance, between the two. But I rarely use 18350s of either brand in my mech mods.

 

[JMarca]

For your .4 ohm coil I'd go no smaller than an 18650 and no less than an AW 18650 1600MAH battery.

Now not many people I know vape at .4ohms, you might like it but you also might find that it's a little too hot. If you're desired resistance is really around .8 ohms I'd go no smaller than a 18490-18500 and those efests should do the trick. Don't vape sub ohms on any 18350, it's not really meant to handle that kind of torture.

It's not the performance that concerns me. It's, like I said, that I have received clearly different relabeled batteries as efests and some of them have been the same as the no-name IMR's. I don't believe they buy cells, add buttons or not, then wrap them...it seems they just sticker other already manufactored batteries. So I wouldn't push them as I would an AW who has a longer history and not just with e-cig folks.

I wouldn't push any of them at 0.4ohms but I don't play near that range anyway.

Be safe and use MNKE 18650s, they have a much higher C rating than AW.
