Who prefers a LR RBA setup?

I doubt the lambo is actually pushing 4.5v if you watch some reviews where people have tested the device under load with a low ohm coil, it may be set to 4.5v that does not mean you are getting 4.5v, grimmgreen goes into this and shows something (these numbers are off but for the sake of an example go with it people haha). if you have it set to say 5.5v it will only fire at 3.4v or something. So it's not actually delivering 4.5v

Yeah that I'm aware of based on the quality of the vape like i said before but it's firing fine at 3.7v

But that was also on a lava tube V1 that he reviewed

It all has to do with the amp limit switch, tesla for an example has a limit of 3amps, evic is around 2.5, so lets say your using the lowest ohm either will fire at 1.2ohms. The evic will only give you 3volts, 7.5 watts. The tesla with the higher amp limit will give you 3.6volts or 10.8 watts. Even a provari will probly only let you get about 4volts. Right now my natural with a fresh battery at 4volts and my aga-t+ with a 0.8 ohm coil is giving me 20watts and 5amps I can take a warmer more flavorfull vape with a 2 second drag then a 2.0ohm coil on the tesla with a 8 sec drag.

Agreed so if the lambo can do 4 Amps then I can easily run it at 3.7-4.0 on a .09-1.0 ohm and not lose any vape. It's when I put it to 4.5 the vape is regulated down. Makes sense. But others say the same device can't fire SLR coils

I am still intrigued.... If any one else who has the new lambo, can you test it out and see if it can run a sub 1.0 ohm set up? I have checked a few websites and all of them say the new ones are supposed to have a 1.0 ohm cutoff. I am almost sure that JUniorNA's Lambo is unique in some way...but who knows maybe the new Lambos don't have a low ohm cutoff....and just have an amp limit...that would be pretty cool.

Finally someone who will give me actual INFORMATION and not just "dude, low resistance and lots of watts is awesome, it's like a steam engine! Don't talk .... until you try it!"

THIS actually makes sense. Lower gauge wire, less heat at given watts.

Thanks!

I don't think saying it is less heat is accurate. It is the same heat as is being generated on a 32g coil. There is more mass in a 28g wire.

Use pressure as an example:
10 lbs sitting on top of a 1" x 1" post generates 10psi spread over a 1 sq" area
10 lbs sitting on top of a .1" x .1" post generates 1000psi spread over 1/100" area and will punch through many materials that 10 psi won't. It is why guys who lay down on a bed of sharp nails don't bleed. Heat spread over a larger area has a similar effect.

Like pressure, spread your heat over a larger mass and no single spot will receive as much heat as it would with finer gauge wire.

Basics out of the way, Couple that with a larger area (mass) heating at the same time and you get more efficient vapor production.

My target is always around 1.5 Ohms when I wrap my coils on all my RBAs. For me, the flavor/vapor is right in my sweet-spot between 3.3 -4.0 V depending on the juice.

 

[ukeman]

cool ... so would ribbon kanthal be a good bet?
If so I wonder what spec's are we looking for comparable to 28g?
I like it at .8 to .9 on my iHybrids and Poldiac... any lower and its a bit too much, but that could be due to the other factors (wick diameter and how its wrapped)

I have heard nothing but good about ribbon kanthal. More area to spread the heat. Apparently you need to find the right gauge to be effective at the voltage and resistance we vape at. Too thick or too thin of a gauge and you will find yourself outside of the sweet spot.

I just ordered some Kanthal ribbon @ .5 X .1 mm, which is supposed to be equivalent to about 30 ga. I won't know how well it works until I get it some time next week, but everything I've read about it seems like it could be a winner. I understand that it might require a few extra wraps than you are used to in order to hit your target Ohm rating (I like low Ohm vaping anyway)...we shall see.....

I hear its a huge pain in the .... to work with.

I've had good luck using the "drill-bit" method to wrap coils, so I don't think I'll have problems wrapping it as long as I torch it first to get rid of the inherent springiness.. my only concern is I'll have to add a couple of extra wraps to get the Ohm rating I'm looking for on my mini DIDs - the wicks are pretty small...but since I'm only looking for about 1.3-1.5 Ohms, I think I'll be OK.

I get what your are saying....but what is important is that the temperature of the 28g wire will be cooler than the 32g wire running at the same watts/amps so I think that is what was meant by less heat.

yes, because of the thicker gauge the heat is more dispersed.

Maybe I truly did fry the circuitry ? For once something falls in my favor lol

if its not broke dont fix it, but maybe it is broke?

 

[USinchains]

Just got some 30 gauge for my AGA-S and moved up into 17w land. WOW is all I can say, the flavor of my favorite juice just opened right up, the little hints of yummy I've been chasing around for a year are now full blown!

I think you broke it in the right way...lol. Most likely...It came from the factory like that....either way you got lucky. If they would make a VV device that had a no low ohm cutoff and had a 5 amp limit....that would just be the best. Who knows maybe the next Provari will have a higher amp limit.

Lol probably right - must have came like that but I don't mind. I did several tests by using the same battery at 3.7 and 3.9 voltage on a mech and then the lambo and the vape is identical. So I'll take that good luck for once

My ideal vape that i've been running is my GG Stealth, 18650's. .9 ohm coil in my Penelope.
