Ego C,DCT 2ohm and 1.5ohm comparision?

[banzai121]

Hi,

I have been vaping since 3 months. I started with ego-t joyetech 650 maH and get rid of analogs with using americano 9mg e-liquid from flavourart. After 10 years of smoking, it was a pretty nice feeling that you are no more slaves of analogs. I have never thought that i could give up analogs so easily. I should admit that the e-cigarette forum helped me a lot to gain more and more knowledge about e cigs.
I was actually really really happy with my ego-t, but the leaking problem pushed me to find new alternatives.So after 1 month i bought a DCT(1.5 ohm) from Smoktech, which i really love. Good vapor production, nice flavour and the tank system without leaking problem is really useful, also you can drag more rougher. However a tiny problem is, that the warmer vape than the ego t makes my teeth ache sometimes. Not a big deal...
Today i bought my Ego-c twist batterie 1000mah, so this is actually the reason why i am writing this thread. I understand the relation between resistance and voltage and the limitation of Amper by Joyetech batteries however there is a question i would like to ask:

So here are some facts(please correct me if i'm wrong):
e-liquid: 50/50 pg/vg, 2 mg nic, green mint
Ego-T Batterie: 650 mah, 3.7 V
Ego-C Twist Batterie(VV): 1000Mah, variable between 3.2-4.8 V. Limitation: 2.5 A
Ego-C atomizer: Standart resistance 2.2 ohm
DC cartomizer: 1.5 ohm and 2 ohm

1) Ego T 650 Mah + Ego-C atomizer(2.2 ohm)= 6.22 Watt= really nice vapour and taste
2) Ego T 650 Mah+ DCT(1.5ohm)= 9.12 W= also really nice vapour and taste

!!!!!!!!!!!!!!!!Now the question !!!!!!!

3) So when i try to vape on Ego-C TWist Batterie+DCT(2ohm) between 3.5V-4.8V i could not find any sweet spot or a satisfactory spot where i get the same vapour production and performance with DCT low and Ego-c.
The Math is right, but the result is bad. WHY? Where do i make a logical mistake?

Welcome to the forum bonzai121, with a vv device you may want to step up the resistance
level of the cartos/attys you use.

I find myself that there is a big difference between even 2.4 ohm and 2.8 ohm for my
taste. 2.8 being more pleasurable.

LR stuff is best on 3.2-3.7 v devices.YMMV

 

[banzai121]

its banzai not bonzai.. So the Ohm math doesnt mirror the truth always?

With 2.8 ohm cartos, it would be not warmer but smoother, am i right?

1 more question; so if you can variable the ohm voltage=watt relation and effect, where does the difference(2.4 or 2.8 or 3ohm) come from?

 

[banzai121]

do you prefer lr ego c atties?

If you're using a VV device, it makes sense to me to stay away from LR anything and increase the resistance as much as possible to provide much more room for adjustment. The burnt taste shows up quicker at higher voltages with less resistance. You can change the voltage on your VV PV but the atty's resistance remains consistent.

I think a 2.8 would eliminate your problem.

EDIT:

To clarify, here are some examples:

Let's assume you're using an atty rated @ 2.8 with the twist.

Set at 3.2v = you'd be vaping @ 3.7w
Set at 4.0v = you'd be vaping @ 5.7w
Set at 5.0v = you'd be vaping @ close to 9w.

Same PV, this time using a 2.0 rated atty.

Set at 3.2v = you'd be vaping @ 5.1w
Set at 4.0v = you'd be vaping @ 8w
Set at 5.0v = you'd be vaping @ 12.5w

The difference can be pretty substantial, even between a 2.5ohm and 2.8ohm atty.

Since the Twist only has a 2.5 amp switch regulator, it will NOT like any atty or carto in the 1.5 - 2.0 ohm area. It limits what you can use on it. It will drop the power output due to the small amp SR.

I use 1.5 ohm dual coil cartomizers and they really shine around 4.5 volts. But you need a PV that has 3.5 - 4.0 amp switch regulator. Something like the new VV Gripper from MadVapes ($59) or a Provari, Darwin, Silver Bullet with a Kick, etc.

lots of good info on here , thanks

 

[Amadodesertlady]

there is good info, but i am so new, that I just don't get it - all seems a bit complex. I have an Ego with 650mah better and a Vivi Nova tank - the tank comes with two spare atomizers. The 2.4 is what was in the tank and what I am using. I don't quite understand how my vaping experience will be with either the 2.8 or the 1. something or other.

I don't think I agree with this statement (please correct me if I'm wrong, however).
My understanding is that you can take a 1.5 ohm atomizer up to 3.7 volts and still be at just 2.47 amps.
Similarly, 2.0 ohm at the Twist max of 4.8 volts is only 2.4 amps.
Still under...

I try to target a sweet spot of about 6.8 watts myself which happens to be 1.5ohms@3.2v or 2.0ohms@3.7v.
Both of which the Twist should be very capable of.

Whether or not you should be drawing > 2 amps from an eGo battery in the first place is an entirely different conversation.
But, I see batteries much like the rest of an eCig, a consumable, disposable item.
If using 1.5's will shorten the battery life, so be it.
