If you have 3.2 Ohms going in, half of it or 1.6 ohms goes to each coil. That's the easiest way to explain it.
Coil 1 1.6 ohms
Coil 2 1.6 ohms
2x1.6 = 3.2
Your Darwin should see it as 1.6 ohms. If you unhooked one them your Darwin would read it as 3.2 Ohms.

That is kind of a broad statement, I wouldnt quite say that. It depends on the size and type of battery, they say not to use ego batteries with the dual coils and I think that if you were to use a 16340 that it would probably be a good idea to use high drain batts. For me they have worked good at low voltages but I only use high drain batteries and it seems like the vapor production at low voltages is not the greatest but that is the least of my concerns because I am a throat hit junkie. At higher voltages I get much more vapor and the throat hit gets pretty crazy. What batteries do you have, besides the darwin?
Ok so tell the electrical stupid , whats a IMR bat? Translate this into something a child could understand if they only knew how to turn on a light switch please ! LOL !!
Thanks !
Thanks !
Switched was responding to the comment I made about only using high drain batteries, high drains are called IMR. For instance if you wanted a high drain 16340 high drain battery then you would buy an IMR16340. I do not know what it stands for but it is a designated abbreviation for high drain batteries.Ok so tell the electrical stupid , whats a IMR bat?

edit; Just to be clear I am no type of expert, the way that I understand it is that high drains are capable of draining fast enough to keep up with the low resistant atties that I love without damaging the batteries. They also run at a slightly higher voltage through the charge of the battery. I am sure that others will come in with a better explanation.

IMR = Lithium manganese vs Lithium Ion or Lithium Cobalt (Lico)
They are meant for us because they can handle the load. 1 year ago these batteries were in their infancy. You will normally find them at roughly 1/2 the mAh rating of an LI Ion bat, but don't let that fool you. The IMR batts deliver 2 to 3 times the punch LI Ion carry.

Hey switched I know that this has been discussed not that long ago but at what size battery is it not neccesarry to use an imr? Is it an 18650 where the max discharge rate is high enough with the standard protected li-ion?
I know I'm not Switched but the answer is yes, the 18650 for sure.
Someone told me that the AW 17670 falls in this category as well but I'm not sure about that one...
True Vap... I believe we can get away with the AW 14670 as well. Below that IMR all the way especially stacked in HV or VV regulated devices.
I have a DIY VV box mod with 14500s.
The DC carts sucked on my friends riva! The single coils were pretty good, actually they were quite good.
Hiya Mini! To put it simply darlin. Atomizers themselves require a good amount of energy to make that coil hot. an IMR (high drain) battery can give it out much more easily than a li-ion causing less stress than a li-ion would. IMR (depending on the size) will give 4.19V all the way till the battery is needing to be recharged again. The 16340 will always have a 4.19v output, giving you the fresh off the charger feeling for it's entire run time. The li-ion will give you 4.19V but only for the first few pulls.
Hey Gregory,
Yep, the DC (Dual Coil) will work on 3.7V but remember it's a DC it needs more power to make it nearly as hot as an SC (single coil) on just a plain ol' 3.7V it will perform and may live for months without a problem but it will be weak.
The 1.6 Ohms is the result of 2 - 3.2 Ohm coils wired in a parallel circuit. The parallel configuration drops the overall resistance of the circuit. That's the resistance you get measuring at the connector. If you had 2 - 1.6 Ohm coils in series you would get 3.2 Ohms measured at the connector.
Your Darwin is measuring the resistance of the entire circuit properly. And if you unhooked 1 coil it would indeed read 3.2 Ohms from the 1 remaining coil.
