Mechanical mod questions.

I apologise if i caused any confusion.

I do not build anywhere near 0.1Ω.

I build 1.0Ω, or a dual coil that has a 0.7Ω resistance.

My Sat22 clone cap had a pice of shaving from when it was machined. I did not see it. It shorted onto pos pin of atty. Tesla Sub Box would not fire it.

With the resistance that i use, i never drain these boxes. They never get warm, either. Have no idea if one tried to build super sub ohm. I do not vape that low.

Peace, Annie

I had no problems understanding you It was a short and the board protected you. What is questionable and remains unknown is how would those batteries handle stress test. Being fired repeatedly at minimum allowed resistance would they eventually overheat and vent, would the board protect them from overheating as well, or is it just over drain and resistance protection.
That's why i said it doesn't matter what they say since there is no verification for it

Gotcha!!

The only thing that really makes me MAD, in the world of vaping--is inflated battery specs--and the people that profit from such claims.

I am glad that we have a resource for good battery information. I am satisfied with tamer atty resistances in my setups.

Our batteries are VERY mild in that respect. Very, very mild.

AND very mild in the realm of electronics in general.

For example... try to pair up a 1100 Watt speaker to a 1000 watt amplifier without blowing something. THAT'S touch and go, guaranteed.

There needs to be integrity, in science, in measurements and data recording.

Science is what i do for a living.

In college--our profs cautioned us on 'sink-testing'.

I mean, if merchant XYZ made a claim such as 'Oh if you buy my atomiser, or my battery, you will make Big Phat Cloudz'--i wouldn't bat an eyelash. 'Cloudz' are subjective...and i can understand the profit motives behind advertising claims and its language.

But to lie with the numbers--this will always make me sour

Agreed...

But then there's marketing.

Say Panasonic has 3 home audio lines at 3 drastically different price points.

Though clarity and range may be drastically different and you're getting what you're paying for, the higher end gear won't sell as well at 3 to 5 times the price if it's 1000 watts isn't drastically louder than the 1000 watt budget gear.

Makes it tough matching up car audio gear especially. Those numbers are out of hand....

You should see what's happening on FB groups here in Edmonton. It is simply unbelievable. Shops are promoting Efest as a good quality cells, advices to buy ICR batteries are given and in the same time majority of them is using Dragonskin fused nuclear warp 9.5 coils with no resistance literally. And then they all start screaming like bunch of ducks when someone gets hurt. It just makes me sick and tired of explanations. I think i'll sign off from all those groups and leave them to their destiny. Can't fight the windmill's any more.

H4XOR, you sent me a PM last night but i guess you have deleted it since i can't access the msg any more.
It doesn't matter what they claim, if you can find a review on youtube where the mod it self gets tested with proper equipment, like theone PBusardo does for example, then you can play with minimum resistances knowing that it should work safely with those loads. I told you, and i still think the same no matter Annie56 said the protection works, it is best for YOUR safety not to go so low with resistances. There is a term for that, and it's called FALSE ADVERTISING. Do not put you health in someone's else hands with untested equipment...

EDIT:
Trying to find something about those batteries based upon the markings, but nothing came up so far. I couldn't even find ANY 19500 Battery that is Li ion. The one i find out was Li Fe Po and it was on aliexpress, so God knows who's the manufacturer. Anyway. To get stable 40 Amp discharge, means you'd have to have 2 pieces of 20Amp batteries connected in parallel. As far as i know, most of the 18650 batteries are at their limits being discharged at 20Amp current. Smaller battery can only have even worse rating, so i would definitely keep my self on a resistance of at lest 0.3 Ohm or above.

Alright! I sent you the PM and didn't delete it, odd that you weren't able to see it. But anyways, I may just stick with 0.5 sub ohm coils. The tank comes with 0.5, 0.25, and 0.15 nic200 coils in the box, definitely not using the nickel coil, not for my setup. The 0.25 is touchy here and if you say it may be too low, I probably won't trust it. But thanks for your response! Much appreciated!

EDIT: yea a lot of people find it weird that it uses 19500s and saying they never seen those batteries. It's weird really, but they are 19500s.

I have some 80a 18650's.........Sharpy works wonders

As with everything, i will always advise caution in first place. If you want to try 0.25 go ahead and try, but please monitor the temperature of your mod. If at any time mod becomes suddenly hot, put it on a safe distance and let it cools of for couple minutes. If the temperature builds up slowly and doesn't reach the point where holding in hand becomes uncomfortable, it is PROBABLY safe to use. I'm saying probably because we don't know what kind of batteries are in it. I hope you understand what i mean. I used to play with batteries from laptop (really had no money to buy decent ones. long story you don't want to hear) but i was using a regulated mod with all kinds of protection and was not exceeding 10W limit, so i had no problems. But playing with unknown batteries wit so low resistances can lead to a disaster very fast...

Alright I got you! I'll just have to use extreme caution with what I do, I may just stick to 0.5 or so for piece of mind! Yea I'm new to mods so I'm learning as I go! Just wanna avoid a huge hazard lol thanks for your responses!

We all learn as we go, that's why we are here, to learn and to share knowledge and experience

It's not wierd, just not the type of cells most think they are.

19500 means 19mm diameter and 500 mm length.

It's the physical size of the cell.
It tells nothing about it's specs or chemistry.

Those are not removeable batteries, they are tabbed LiPo cells.
They are not like our IMR removable batteries

I agree with the above. LiPo batteries are not safe chemistry batteries like our 18650 IMR/INR batteries. Just ask any of the remote control hobbyists who use LiPo batteries in their cars or airplanes.

Deeper Understanding of Mod Batteries Part 1

• For those who want to learn the differences between IMR, IMR/hybrid, ICR, and LiPo batteries. What do those numbers and letters on batteries mean? What's an amp rating and why is it more important than the mAh rating when choosing a battery for vaping?

Oh wow! So how can I really tell which battery chemistry is used for my mod? Of course, people have said that they can't find ANY info on a 19500, does that mean there's no way of telling which structure these batteries are made from?

EDIT: Looked back at some posts in the thread, they are LiPo batteries. Hmm...... this concerns me...... I'm not sure if I should trust a .25 coil, I may stick with .5.

Li Po Batteries in so small form with 1500 mAh rating?As far as i figured so far about thse Li Po batteries, beside of being quite violent if not handled properly, the have lower capacity then standard Li-ion.
I don't think it's Li Po due to 5.92 Wh rating that leads us to average 1500 mAh per cell, which, considering a bit wider diameter would be nothing uncommon for a 19500 Li-ion battery...
18500 are rated for 1100 mAh in average. At least mine AW 18500 are...
Unfortunately, there's no way to be sure either statement is true...

You don't have to be afraid of LiPo's so much. I'm using Evic VT, it also haves LiPo pack in it, similar to the one from the video above for over 6 months now, and still works like a charm
In fact, i've seen more accidents with Li-ion bateries used in artificial hybrid connections then with LiPo packs used in proper enclosure with a protective board....

They are LiPo batteries, wired internally into the mod.

This is a common way to build these.

No, we don't know the specs beyond what the mod manufacturer states.

I'm not saying yes or no, i'm just surprised with the capacity. Usually LiPo batteries of that size wouldn't be more than 1000 mAh each. Theese are almost 50% more. Of course, it is possible that manufacturer is false advertising them...

Annie56, you said you have one. How would you compare it battery wise to a standard 18650 battery?

19500 is only the size of the packaging.
It has nothing to do with the specs.

I have a much smaller 2000mah lipo in my cell phone.
