AGA T2 Confusion

[Haber]

Hello guys, new here and have been lurking for a loooong time. Loads of threads have been very helpful and educational and have helped me progress from cig-a-likes down the road to VV and mech mods.

Here's my issue. I purchased an AGA T2 and wrapped it with .32 Kanthal 4/5 wraps on a SS mesh wick. Put it on my Evic and it registered at 1.5Ω. Fired it at lowest voltage to check for hotspots...nothing. moved up to 3.5V...nothing. Moved up to 4V held the fire button for 6 seconds and finally got some glowing. Worked out all the hotspots by poking and prodding with a blunt syringe tip until it was glowing evenly. I found it odd that it took so long for the Evic to fire it up at 8W but I filled it anyways and gave it a few test vapes and it produced little vapor. Very disappointed and confused to say the least as I wasn't getting any "atomizer short" messages and was firing it at upwards of 10W and very little vapor was produced.

Next day I decided to go and purchase a pure mech mod because of all the reading I had done here regarding gennies and how they perform best on an unregulated mech. So I picked up a Kamry K100 and a couple AW IMR18490 batteries and popped the AGA on....Tonnes of vapor and amazing flavor. Now I'm really confused so I pop a 1.8Ω EVOD on Evic and set to 4.2V (roughly fully charged mech batt) and compare vapor to K100...Exactly the same. Do it again with a few other clearos I had and same results.

Long story short...Why is my Evic having such a tough time firing the AGA T2 at the same voltage as my mech mod when there is no hot spots and it is not shorting out?

Any help would be greatly appreciated!!

Not sure why this is happening, but there are several YouTube videos with people using AGA-T and Evic with no problem.

IMO, Evic is not compatible with genesis tank. It would be a waste for a great RA like AGA T on Evic. AGA T can be a killer fogging machine if set up nicely. My MVP can fire AGA way better than Evic.

Ya I saw the videos on youtube as well which is what really confused me considering the Kamry fires it like a champ. I tried cleaning the 510 connector and on fully charged battery as well even though I don't think that should matter considering it's regulated and will fire at the set voltage or wattage regardless of battery power and still poor results. I guess the Evic won't be used for rebuildables in the future and will be retired for clearos only.

Here's an example-

Yeah, Genesis style setups work best at lower resistance (higher wattage) to get the best flavor and steam.
Also, it is critical the intake hole is aligned properly or the vape amount and taste falls off.
Myself, the AGA wicking could not keep up so ended up removing the second grounding post (useless anyway for me) and made a ss U wick and seems to work much better. I believe this wicking issue is due to hole size being smaller then most.

I've gone thru a metre of Kanthal, a 12"x12" sheet of SS 450 Mesh and 7-days of every Aga-T tutorial / vid / review, including eHuman's blog... but nothing works for me. I've lodged my woes HERE. And finally ditched my Aga-T2 for my usual Carto-Tanks.

I've got two AGA T2's that I've been using for a few weeks now, on both 2 Provari's and a Silver Bullet. I am pretty happy with their performance, although I have experienced a lot of the "wandering ohms syndrome" which has been said to be due to loose contact of the coil on the positive pole or unseen hot spots in the coil. I still consider myself in the learning stage with these, and I've not found them to be as dependable or as consistant as my cartotanks. But when they are working well, they surpass the cartotanks in flavor and vapor.

I prefer a cooler vape, so I'm not a fan of the ULR coils that are so popular with RBA's. I make a 2.0 ohm coil from 30 g wire and use pre-rolled stainless steel mesh wicks.

The evic may be limited to 2.5 amps by the software. I'm not sure if there is a firmware upgrade or not as I do not own one. Will your evic fire it under VV mode, using voltage instead of watts? Does this change the vape at all? Does your coil *still* read 1.5 ohms? Around 4 volts should simulate the same power as the mech. VW mode may be having a struggle due to the evic trying to constantly poll the atty and for some reason at least partially failing in doing so.

 

[Haber]

This is my setup at the moment on the K100. I would take a picture of the vapor on the Evic as well but I'm stuck at work! The vapor I'm getting from the Evic is about 1/4-1/2 of what the Kamry produces.

That's an excellent point the readings have been very similar anywhere from 1.4-1.6Ω. I have only been using it in VW mode since I got it. Once I get off work I will go home and give it a shot on VV and pray. Thanks for the help as that makes sense. (I did purchase a multimeter as well...forgot to get batteries for it so I will take a proper reading of it tonight as well.)

And then I went ahead & ordered two more RBAs (sic!)... an IGO-L and a Smok RSST. With both I'll be using Silica instead of SS Mesh - and hope things'd work-out.

I stand sanguined that a Carto-Tank is our best juice delivery option, at least for the general vape [re]public. In all my 3-months of vaping I've not yet got one miss from my Boge XL Flanged F-16 Cartos. They have been rock steady in performance... and so damn easy to replace, fill, handle by adhering to Bad's blog. Besides, they top in consistency... u don't need to think twice at picking-them-up and run... they will deliver... that much faith I've on them!

Just that I forever wanted "all SS tanks" on my Mech.Mods. To get that intrinsic hybrid look. If only Carto-Tanks came in all SS, or with a small window - then I wouldn't have been scouring the www - and been content! Thus, the IGO-L and the RSST (both in post already from HV), either of which will look as good as the Aga-T2 on my Sigelei #8 & GP Paps.

Fingers remain crossed!

Wow! I didn't know you had been having problems! If I can do a SS mesh coil on an AGA-T2, *anyone* can! I'll look at your "woes" thread and see if I can't toss something into the ring that might help.

Here is the deal... Basic electrical "laws":

Amps = Volts/Resistance
Watts = (Volts x Volts)/Resistance OR another way: Watts = Volts x Amps
Volts = square root of (Watts x Resistance)

Let's say your coil stays rock steady at 1.5 ohms and what I thought about the evic being limited to 2.5 amps is actually correct (I'm not sure it is... just remember reading that elsewhere):

A fully charged battery in your K100 (leaving "voltage drop" out of the equation for simplicity) should be around 4.1-4.2 volts. Let's call it 4.0 volts just to drop a decimal point, as if you have been vaping on it for a couple of hours already...

4 volts divided by 1.5 ohms = 2.66666667 amps, just a hair beyond that 2.5 amp limit that I suggest might exist. No problem for your K100 but the evic.... Hmmm... If your coil even dips down to 1.4 for a split second that will of course make the problem even worse.

10 watts in VW mode? The square root of (10 watts x 1.5 ohms) is... 3.87298 volts. 3.87298 divided by 1.5 = 2.5819889 amps... almost 2.6 amps but not quite.

Now suppose that K100 DOES have a fresh battery in it at 4.2 volts. 4.2/1.5 = 2.8 amps... and 4.2 volts x 2.8 amps = 11.76 watts... not a huge difference but if the evic is fluttering just over it's 2.5 amp limit it may be protecting itself by pulsing the power... on, until it's too hot, then back off, then back on again, etc.

math.. it makes sense..

Just wanted to thank everyone that chimed in multimeter read 1.4 ohms. Max voltage for amp limit of 2.5 is only 3.5 and 8.75 watts. Much less than the mech is pushing. Evic software was confusing as you can crank it up to 11W but I guess it doesn't mean it's actually putting out 11W.

Anyways just wanted to say thanks once again this community rocks!

Here's the setup which I came up with to help wicking. 400 SS hybrid U wick with a twisted pair AWG 33 Kanthal A wire.



Works well as I need all the help I can get vaping 100% VG due to PG allergies. Also removed fill screw and replaced with shrink tubing leaving a smaller hole for venting. Note I had to fix the winding slightly as there was a hot spot in the last loop which can be seen in picture. I actually removed one loop completely to bring the ohms down to 1.5.

 

[angst]

Damn. This is the set up that I was planning on going to.

got mine to work after a few attempts great production, flavor improved as i used it. used it most of the day. then the cap wouldn't come off. literally fell apart as i tried to pull the cap. put it back together, hasn't been the same since. getting better performance from the 8 dollar cobra i bought from fasttech. the ironic part, i get better satisfaction from a regular drip atty. thought they are a bit over priced, but they really bring the flavor out. thinking of looking for a rebuild able drip atty. in the beginning i thought dripping was a lot of work. but as i get used to it, i find it isn't as bad as i thought it would be. anybody want to suggest a easily rebuild able drip atty?

Hey Pipes where are you getting your 100 VG juice from? I pretty much vape VG exclusively myself and get it from Jugheads in Alberta and haven't had any issues with the wicking. If you haven't tried his VG line of juices out yet I highly recommend them! Some of my favorites are his Swedish Pastry, Awesome Waffles and H20 Melonz.
