If you dont see any diference to a single atty with those batteries then you will not see in 2 atties or more atties. My opinion as I posted from the start was that there will be not a noticeable diference. But even if I am wrong to this (tecnical data that we dont know for sure), is it possible to compare this 3,7 volts vaping to 6 volts vaping?
You cant have big results with big titles like: "6v is not the answer HIGH DRAIN CELLS is the answer!!". The title of the thread is a little funny to me
But lets try to see some things:
high drain battery means that it release more current. The ohms law says that:
current =volts/resistance. So if we know the resistance of an atty and the volts that the battery produce then how the current is increased?
If current increased then yes the diference exists. Its like we smoke at 6 volts. The current at 6 volts that goes through a regular atty is 1,7A when its 1,1A at 3,7 volts.
The conclution for me is that there is no diference at all. If I miss something here I will be glad to hear it
Let's look at it this way...whats the amp draw with a 3.7V battery running a standard 2.2Ω 510 atomizer.... 1.68A right?
so you want your batteries to be able to deliver at least that or risk possible battery damage and reduced service life...you want your max discharge rate to be higer than that so that the batteries ae stressed less so that their service life as well as how long you can vape them between charges...
So lets look at a bunch of the 3.7V batteries and their C rating in terms of their max discharge rate...
Ultrafire CR123a...880 at 1.5C...max discharge is 1.32A
AW CR123a...750 at 2C....max discharge is 1.5A
AW IMR 16340....550mAh at 8C...max discharge is 4.4A
Ultrafire 18650...2400mAh at 1.5C...max discharge is 3.6A
Ultrafire 18650...3000mAh at 1.5C...max discharge is 4.5A
AW 18650...2200mAh at 2C...max discharge is 4.4A
AW IMR 18650...1600mAh at 10C...max discharge is 16A..
So using a CR123a battery alone or with a dummy battery won't meet the amp draw and will possibly cause damage or reduced life of the battery except with the high drain...
On the 18650 batteries it translate to how much stress and draw is put on the battery and yeah how much time you get out of it..all of them will perform sufficiently it just depends on how close your amperage needs get to the max draw of the batteries (let's not forget too that when the batteries are fully charged that's closer to 4.2V which would result in an amp draw of 1.91A)...aditionally, with the new trend toward these low resistance 510 atomizers we're looking at a 2.8A draw (4.2V with a 1.5Ω atty)...so we're approaching the max draw of the small ultrafire 18650, though we havent met it yet...here's where my understanding is fuzzy (I believe the more amps you have available to draw upon, the less voltage drop you'd get too)
by that measure the high drain AW 16340 has the same power available to it as the 2200mAh AW 18650 but it could only provide that for about 7.5 minutes where the 18650 could hold it for 30 minutes...thats at max continuous draw..

Concerning these: "AW IMR18650 1600mAh LiMN rechargeable lithium battery"
For anyone that uses the MBT-1 battery tester from ZBT, I asked them if the tester accurately tests the high drain LiMN chemistry of this AW battery. It DOES, this was the response:
"The Li-Ion type cells are nominally 3.6/3.7V, however when fully charged they are a little over 4 volts. The tester is programmed for this type of cell/discharge profile, and from you description it sounds like everything is working properly. Also, the open circuit voltage (no load) of the battery is higher than when under pulse load."

Drodz those batteries are good for other reasons and not for throat kick or smoke. They are good because they dont get damaged easily because of our vaping needs and they keep the current draw steady. But they cant take the place of 6 volts vaping in any possible way. So I think you agree here
the new chemistry should enable a high current, with less voltage drop compared to the old cells. thats all. because of that, they may deliver enough punch to fire up a both atomizers of a double barrel as much as an old cell fires a single one.
[edit] because the voltage drop under load is lower, the wattage is higher.
there is a difference, even between older cells. i have soshine 18650 protected cells that work better on the double barrel than unprotected grey ultrafires.
i am very interested in trying the LiMn AWs out, but in germany i have trouble to get some.
If you can't get the high drain AW in Germany, you can still try alternative brand.
Like the very fine precursors: KONION, or A123....

I don't know Imeo.... I have not picked up my 6v rig in days.... With the i3 and one of these HD batteries I am satisfied completely. I take long slow drags and get huge throat hit and vapor too. They are worth investing in.
