Great show Jan.

Hi jan, i use my provari with a dc 2 ohm at 5 volt.. Is that still putting out 5 volts or dropping like the lava tube in ur video?

 

[Moofaso]

well done Jan !

 

[izdalion]

SteelJan I love your videos You make information so easy to understand and for me I need that. Love it! Great video and looking forward to more in the future.

For the tree to better represent a 5v running a 1.5 ohm atty...it needs to blow up the tuna can.

Nicely done Jan. I like your graphical representation of voltage drops and current limiters.
When I got my LT I tried using my old blue protected Trustfires and they worked OK, until I tried to crank up the voltage beyond what the battery's actual voltage was. Then I got nothing. I thought the battery protection circuit was kicking in. Then my genuine AW IMRs arrived.
I figured you needed the higher current to be able to ramp up the voltage in the booster circuit. And what I've always heard about the AW IMR is that since it's not Lithium Ion it can crank out the higher current without fear of explosion. That's why it's not protected.
Now an unprotected Lithium Ion? I did have a bad experience with one, just once. Needed a minor repair on my REO because of it. But I have no concerns with my AW IMR.
Of course, this is all just what I've heard.

IMR batteries have no protection because they were designed to be used in battery packs for industrial applications where undervolting, overvolting, and short circuit protection is provided by the equipment using them. They were never intended for stand-alone use by the general public.

There's a youtube video, drat, can't find it right now, where a guy shorts out an AW IMR 18650 battery. It does not explode. But it burns and melts the wiring and its plastic casing, and it reaches a max temperature of about 240F pretty quickly.

On volcanoecigs website, they say that the Lavatube's electronics provide undervolting and short circuit protection.

There are some rumors that AW is going to come out with protected IMR batteries.

So far I'm okay with my protected 18650's in the Lavatube. I prefer standard resistance cartomizers and my sweet spot is around 4.2V.

I've never had a Provari. The functionality is the same, so I suspect it would not show 5V if you measure it. If it does, then measure your 2ohm dual-coil cartomizer to see what it really is, it may be higher than 2ohms.

thanks steeljan! I love the visual! Kind of like "voltage for dummies" lol (of which i freely admit i am one with regards to that kind of stuff). Great video!

 

[SailCat]

Bravo, SteelJan! Excellent video explained concepts in a manner that anyone can understand. Bah to videos with 'special' effects & long musical intros intros that end up showing someone vaping in a laundry room. Your film has soul!

Keep it real.

 

[Dom C]

Awesome and informative video as always SteelJan! I've been hoping you would do a review of the LT since I knew you'd explain it in a way I would understand, enjoy and trust. I was hoping to see some under load voltage testing though as I've heard mixed reviews about the LT's performance under load.

TMI before thought id break down the question :l i tend to type too much sorrie
________________________________________________________________________
Edit: I thought what it all boiled down to was Watts and that once you found your sweet spot(which depends on flavor sometimes) it in reality is your watts your putting out thats the sweet spot
example: I vape at 6.7v using a LR carto "rated at 2.0 ohms"
for this specific flavor my sweet spot would be 22.445watts
So to achieve this wattage on the Lavatube i would need an attie/carto higher in resistance?
D:??? math tells me no so that means im missing something or am using the wrong formula or something can someone clear this up for me?

Guys ive been vaping for 2 years i dont even consider myself a moderate experienced vaporer (lol i know thats not a word YET but it will be xD) i thought i understood ohms and voltage but now im cumfuzzeled so please correct me if im wrong but i thought an LR attie would "weigh less" than your standard attie therefore causing less of a "droop from the string" really want to understand cause im trying to learn i apologize for my misunderstanding in advance someone whos vaped since they were in highschool(2years) should understand this by now

Ok, I'm certainly no expert (and to those who are experts, feel free to correct me) but that might help since I won't be using too much technical jargon. But basically LR atty's draw more current (or amperage) from the battery. Amperage = Volts/resistance. The Lava Tube is limited to about 2.5 amps. So an LR atty will start to reach that limit sooner than a standard resistance atty. For example a 1.5 ohm atty at 3.7 volts would draw 2.47 amps (3.7/1.5=2.47) which is almost at the 2.5 amp limit. A 3.0 ohm atty at 3.7 volts only draws 1.23 amps (3.7/3.0=1.23) which allows that 3.0 ohm atty to get to a much higher voltage. A 3.0 ohms atty at 6 volts only draws 2 amps (6.0/3.0=2.0) which is safely below the 2.5 amp cut off allowing you to use that 3.0 ohm atty at any of the possible voltage settings on the Lava Tube. Wow i didn't realize how well I understood that (assuming I'm correct) until I wrote it all out here lol!
Also, SteelJans video with the toaster might help as well. steeljan's Channel - YouTube

Did you mean 3.7v? There isn't a variable voltage out there that can get to 22.445 watts (well maybe Ken's box mods style box mods). Generally this is the arena of people who vape at 7v or 6v on fixed volt devices.

Just saw that you edited your last post while I was responding to the original. I'm pretty sure that 22.445 watts cannot be achieved on the lavatube. Your current setup is drawing 3.35 amps which is well over the lavatubes amp rating. I used this for the calculations Calculations voltage current resistance and electric power formula calculator general electrical pie chart - electricity calculation - electrical power formula general ohms law physics electricity electronics formula wheel formulas amps watts volts o. Again I'm no expert so if I'm wrong someone please feel free to correct me, preferably with an explanation.

ok maybe i should explain my set up(and calculations because i suspect those may be wrong as well) might clear some stuff up
Maxi rough stack
1x3.0v ce2 battr.
1x3.7v 18350 batt
1x 2.o(advertised) ohm carto
Calculations: watts formula(the one im using that i got from google) W=V^2/R(for those who dont know ^=to the power)
I like very warm vape i also find IMO that it brings out 90% of dekang flavors BUT i do get minimal use out of my MEGA EGO Dual Cartos
I want a VV mod but what kept me from buying the lava tube is the cut off
Breakdown: So my worries is that HR attie will take away from the warmth and flavor of my super cheap eliquid
Side question: is it true that pure VG is better for high voltage deices? due to its viscosity keeps atties from burning up better than pg??

Again I could be wrong but I'm pretty sure you're not supposed to stack two different types of battery together. But what do I know? I only have an ego. But I believe your calculations are correct although I have no idea how you could possibly enjoy vaping at such a high wattage.

 

[Goldenkobold]

Your stacking the 3v battery with the 3.7v battery? I don't think that is particularly safe.

But if that is what you are doing then yes...assuming the power is properly going in the from battery to battery to atty you are getting 22 watts. Neither the Lavatube nor the Provari or Darwin will get that high in wattage.

No its not true that VG is better in High Wattage vapigng it tends to burn and can't wick as fast...that is my personal opinion but I have never enjoyed VG (which I like) at the higher wattages (even at 5v with a standard carto I find it can't wick fast enough)

 

[imb1610]

well on madvapes website they actually advertised it thats the only reason i said ok ill givit a try but if theres something wrong with it guys please let me know(and why its bad would be helpful too lol juss curious so i understand and learn)

Important: I just went back to madvapes website to check amp limit and i found this now what does this mean?"Comes with a replaceable 3 amp switch assembly" does this mean i am capped at 3amps?
@ Dom C: yea idk y either just tastes better to me the warmer vape helps me feel like im smoking a REAL cigarette but its way tastier but see since its not Variable voltage and am limited to about 4 diff. settings i dont feel like i have the freedome to explore other wattages to find my Real sweet spot but from what i have learned is that i do like a warmer vape(steeljan sais some people say they like it just to gloat but i assure yu i actually enjoy it BUT if there is a better sweet spot i feel i must find it)
