RBA on eVic

[nufan]

I went to my local B&M store today to get some juice and was inquiring about a Nimbus clone they had. Basically the guy told me that a rebuildable dual coil on my eVic would probably disappoint. I like to vape with 2.2 ohm coils in my protank2 and that would mean at least two 4 ohm coils on the Nimbus.

Does anyone have experance with RBAs on a like mod?

IMO I don't think the guy at the B&M knows what he's talking about. I have a 2 ohm micro coil in a Smok mini RDA and it works great. I use it on my MVP2 and ego batteries. I get pretty good clouds with it, thick enough where if I roll the vapor out of my mouth I can't see through it! The lowest I've ever built was a 1.3 ohm coil and honestly I didn't notice that big of a difference compared to the 2 ohm.

I say make a dual coil the way you want, attach it to what you want and vape away (safely of course)!

I run a Kayfun clone and before that a Aga-T2 both at around 1.7ohms on my MVP1 no problem. I do check with an Ohm checker first to be safe. But it fires them just with fine gobs of vapor and flavor.

Number one rule of retail. Gotta up sell. Now can I show you a nice mechanical mod over here in this case...

eVic, anything running in the operating range will work.

Generally people run RDA's at lower ohms. That said, you can build 2x higher or even run 1 coil at whatever performs within range.

Like many above, I've had all the vape I can handle out of a 1.5 ohm microcoil (RDA, Genisis, Kayfun, etc.). These can run on any reasonably powerful regulated PV just fine.

I think the B&M guy is referring to having to have 2 hella high resistance coils in parallel to make your 2.2 ohm goal with that RBA fully tricked out. You can, of course, just run 1 coil of any resistance above 1 ohm in it on your evic.

Thats what I thought, but he made it seem like it wouldn't perform any better than my PT2 (which I'm not that impressed with)

An eVic couldn't do what I want out of a dual coil. Does great on RDA and RBA single coil 1.5Ω-2.2Ω though. Don't forget the amp limit on an eVic.
I have a dual RDA around 1.3Ω that an SVD or a Vamo can push hard enough (barely) and a 1.5Ω dual RBA that requires stacking on a Vamo to give me joy.

don't know what amps I usually run, but on a 2.2 ohm coil in my protank2, I like about 5.5 watts/or 3.47 volts.

I don't remember if an eVic is 2.5a or 3a, I think it's 2.5a.

Let's say you used your 2.2Ω coils as a dual and got 1.2Ω or your eVic fired 1.1Ω. You'd probably want 11w. If it's 2.5a you'd be over. If it's 3a you'd be a little over.
If you went with 4.4Ω coils to get a 2.2Ω dual you'd probably want more volts than eVic would do (I really don't know, I've never tried 4.4Ω but I know when I start getting higher Ω coils I have problems getting them cooking like I want which is why I had to go to 5v to get 3Ω coils cooking in a 1.5Ω dual).

Your mileage may vary. There's wire gauge to consider too (when I tried lighter gauge to get them cooking faster I had a burning problem so I didn't mess with it long).

If my math is correct then 5.5 watts with 4.4 ohms would be .533 amps A= √(w/ohms)
or 5.5w with 2.2 ohms= 1.066amps

correct?

EDIT: I used 5.5 watts,because that is normally what i vape at

You're not going to have 4.4Ω. Resistance is cut in half when using duals. 4.4Ω would be 2 - 8.8Ω coils. Everything is figured off what the battery sees (the complete head) as far as what you set on the screen and the limits of the device.
IME, your taste is figured off what the individual coils are, and if you like 5.5w for one 2.2Ω coil you'll likely like around 11w for 2 - 2.2Ω coils (sounds like a lot until you figure that it's 3.47v @ 1.1Ω, roughly the same voltage as 5.5w @ 2.2Ω, that's 3.16a with the 1.1ΩDC).

Given the limits of an eVic you can see how you can quickly hit a wall with duals.

Here's my experience messing with duals.
I like similar coils as what I like in singles. I like 1.8-2.2Ω ribbon singles, I like .9-1.1Ω ribbon duals.
I normally like 3.2v-4v
When I went to 1.5Ω dual (to meet the Ω limit of a Vamo) the 2 - 3Ω coils require 5v, no way would an eVic power that.
My 1.3Ω dual likes about 4.8v, although I use it on a mech and hold the button until it heats up for now (eVic hits the 11w limit at 3.8v with this one, it barely produces vapor).
A .9Ω on my mech was OK but touchy as far as burns with a fresh battery (my eVic reads it as 1Ω and won't fire it).

These are similar coil builds as what I do with singles. Part of the problem with duals is the mass. The rule of no such thing as a free lunch says it's going to take more to heat that mass up. I tried going to lighter wire to lighten the mass but had such a hot leg problem with that RDA that I gave up, a better RDA would probably work better.
So there is plenty of room for you to find dual coil joy on an eVic.
But I'm going with the shop guy and it will PROBABLY not satisfy.

Something like stacking in a Vamo to get the volts up while handling the amps or a VTR to get the Ω down (don't have one yet) is what gives enough wiggle room to make satisfaction more likely.

You can vape anything
On the eVic within its parameters. Keep in mind it does have a 10 second cutoff and it has been my experience that it is a softer hit than others. Personally I like my drippers and rebuildable tanks on my Vamo or mech for this reason. But they work fine on the eVic.


May the force be with you,

Not quite a dual coil, but a twisted 32ga micro coil @ 1.6 ohms works nice on an evic.

I'm with the b&m guy, it will disappoint. Its limited to 11w and thats when the battery is full, i generally vape at 10-12w and if the battery were to crap out at half charge.. meh.
