I have two Tesla Sub Box mods. I can run a 0.7Ω atty all day, and higher resistance for two days. I recharge them every day with a USB cord.

When i rebuild an atty, i use an Astro tube mech, with AW imr batteries. The AW does not seem to put out as much power.

I have a parallel box mod that uses married pairs of Sony VTC5. The pair of Sonys do not drain fast at all.

With the Teslas, they are light in weight. Almost no maintenance. Easy 5 click on and 5 click off. Short protection. I use them on the go, and carry it in a commuter mug. With my tame atty setups, Teslas are really nice. So is my parallel box, tho i haven't taken it out.

Hope that helps!!

So update, I got my Uwell Crown today in the mail, I'm waiting to get lower nicotine e juice before trying this thing out. Now I'm wondering if the protections this Tesla Two has should suffice for being safer, it has short circuit protection, over current protection and over voltage protection, are there threads that explain what the protections do in full? Thanks!

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.

Of course you do. But if you would stress that battery with a 40A discharge current and if she would survive the test, what do you think, how much of a capacity would you get out of it?
We are talking about max 40A discharge here and approx 3000 mAh from 2 19500 batteries connected in parallel.
I know that 19500 is a dimension of the battery, but with capacity comes with size, that's the way it works, and you know that capacity varies dependable on the max discharge battery can handle. 20A rated 1500 mAh battery can easy give you 2500 mAh if discharged at lets say 0.5A, so comparing a cell phone battery capacity with the one from a box mod doesn't really make a sense, or i am completely wrong and have no clue what i'm talking about :D

Short circuit protection will activate once you hit bottom resistance limit with your coil. According to manufacturer that is 0.1 Ohm if i'm not wrong.
Over current protection will protect your batteries from discharging them at the rate higher than the one recommended by the manufacturer, in this case it's 40A.
Over voltage protection should protect your batteries from being overcharged, and that's something all mods with internal charges have, otherwise they would all end up in flames once hooked up to a power supply :)

I have recommended that you don't go as low as 0.1 Ohm because there's no way to be certain how safe that is for the batteries, since noone has torture tested the mod and noone know the manufacturer or th quality of them. You can try, but play carefully. Like i said, if you feel the mod is suddenly and rapidly heating up, put it away on a safe distance and wait couple minutes. If it doesn't cool of in 3-4 minutes, dispose it somewhere safe, where it wont cause a potential fire because it's possible that batteries are overheating and going to thermal runaway (or the fireworks).
It will heat up at low resistance, that's something you can't avoid, it's taking the temperature from the atty, but that's a slow heat up and you'll be able to feel it going slowly up.

What Milandjikic said.

The heat from a radical malfunction is alot different. I had a pos pin insulator melt and create a short, on an atty on a mech mod.

The mod instantly heats up, and it feels like you are holding a curling iron in your bare hands. You will know--in an instant--that something is radically wrong.

I was able to remove the battery quickly. But best NOT to be in that situation in the first place.

I advised against using this mod with super low resistance builds.

That said,
You are making a wild guess about a cell you know nothing about, and have made assumptions that are incorrect regarding this mod.

It is in fact LiPo batteries used in the mod we are referencing.

Other than that, we have no clue beyond factory listed specs unless we test the cell.

It is absolutely possible two LiPo cells can operate within the suggested parameters listed for this mod.

It is also possible that Tesla overstated specs.
The only thing we know for sure is we dont know the battery specs.

I am making wild guess that part is true, since there is only so much real informations available.
Btw, how can you be so certain that the mod is using LiPo instead of some other cells?
I can't find any info regarding those cells no matter how hard i tried, so if you don't mind share your findings with us? :)

Dimensions and specs leave no other currently available options. They're custom mfr'd lipos. I'd bet my children on it.

I have two of these, a tesla two, and and a nano steampunk. I use the two with a .5 to .3 ohm builds usually for tasting, also with a .5 to 1. ohm tank for a backup when I travel. Never had any trouble with either one. There is a slight delay in firing and they don't seem to last as long as my MVP's but otherwise they are solid. There are a ton of reviews of the two on the "tube". I wouldn't lump these into the cheap unknown clone category.

I did see a review where a dude was using a 0.15 ohm coil and it was making HUGE clouds, that said, all I could think was what I was told in this thread and not so sure if that was dangerous! I mean, I hope they weren't NIC200 coils or Titanium on his mod, either way, he was using 0.15 coils, making me think a 0.25 MIGHT just MIGHT be okay, again, that said, I will have to carefully test and see what results I get, keep a close watch on how hot my battery gets. Thanks guys for all of your input on this thread!

I know nothing about this tank. But out of curiosity, i was checking out the threads on it posted in the RTA forum. Something about the 510 pin and connections to the rebuildable section. Does it meter out at the 510 connection? My Teslas fire anything i put on them. Use one of those ohm checkers or a multimetre, if you have one. And this isn't me trying to be a smart***--did you turn it on?5 clicks on, 5 clicks off, like an ego battery. Hope you get sorted

O God.
Like, a hundred years ago--i ordered Aga T2s from fasttech.
I love FT to pieces...

That said, the Aga Ts that i received were--clones. I had to laugh!!

But like everyone else has said, this isn't a mod for a super low ohm build, no matter what the bottom of the box says.

Maybe the build is shorting on the chimney, or something. Just be careful. Even a clone can work. Almost everything i got is a clone. And it all works, pretty much

It's really weird! The coils don't even beat on this one, and when I put my protank 3 back on, it fires nicely. Do you own a Crown? I called the company and he said there should be a authenticity sticker on the back of the box, I don't see one....... Hmm.

If one tank is firing ad second one does not, then the problem is in second tank. Do you feel slight resistance as you're screwing down the atty onto the mod? If you feel slight resistance, that means the positive pin on atty is pushing the positive connection on the mod, so it should make the contact. If not, there's your problem. In case you do feel resistance, maybe try to change the coil, maybe the coil is defect... Go one step at a time

Yea it's weird, it is a tight fit with resistance, just a bit. I tried both the 0.25 coil and then the 0.5, neither heated at all! So what I did was send pics of what I got to the Uwell company to see if it's from them or not, it probably isn't what with no authenticity sticker and what not, if it's a clone, I'm gonna get my money back and buy one directly from Uwell so I'm 100% SURE it's authentic! Weird though, this clone doesn't even wanna work for me!
