Just wondering how 18650 AW high drains would work on a 3.7v. Over kill I know, but just wondering.
High drain batts on a 3.7v

A LOT of members use them exclusively for 3.7v. I have a few in my arsenal as well. IMHO, I cannot tell the difference between using the IMRs and regular 2200/2600mah AW Li-ions(obviously in the 18650 size). I can kill (well drop it down to 3.8v which at that point I can notice a huge decline in vape quality) in about 6-7 hours. With my 2200mah, I can go for almost 12 hours, and the 2600mah last me over 15 hours. In terms of juice usage for easier comaparisons- IMRs last about 2-3 mls, 2200s last me almost 4 mls, and my 2600 can almost get me through 6mls. This is running 1.5 ohm 306s on my Reos
They can be worth it under some circumstances.
Regular li-on 18350 fresh off the charger at 4.17v = load voltage with a 2.0 ohm cisco atty 3.3v
IMR High Drain 18350 fresh off the charger at 4.19v = load voltage same atty same PV 3.59 volts
Though I've compared them before, that test was done just this minute because those things were on the desk in front of me. the difference is a little closer with a 2600 mah AW 18650 li-on and an IMR 18650, but there's still a difference.
The difference grows as the batteries drain. The IMR High Drain batts deliver amps better as they discharge than li-ons do. But, what you give up is run time... It will always be lower mah for an IMR.
That's a pretty big difference.

This is how your IMR High drains will drain for the most part,
4.2V – 100%
4.1V – 87%
4.0V – 75%
3.9V – 55%
3.8V – 30%
3.5V – 0%
Also when running an LR Atty which draws more like 2amp over a reg ohm Atty drawing 1Amp the high drain will handle this 2Amp draw much better. The C rating on your AW IMR High Drain is much higher than your regular Lion/LiNiCoO2 NNP cells. 18650 Batts.

I THINK I can tell a difference with my AW IMR 18650 using dual coil cartos. I can't tell a difference with single coils.
I generally like to throw them on the charger once they get to 3.9 or less, and maybe that's unnecessary, but...

Just for fun, I tested 4 different kinds of 18650 I have. The earlier test of the 18350s was with my regular rough stack. I used the same atty and even the same head cap on one of my maxi rough stacks to test the 18650s. The results produced one surprise, but it wasn't entirely shocking.
AW IMR 18650 - 4.17v off the charger - 3.57v load
AW li-on 2600 - 4.18v off the charger - 3.43v load
Unknown manufacturer IMR 18650 from COV - charged a few days ago 4.14v - 3.35v load
Trustfire Flame 18650 - charged a couple of weeks ago 4.19v - 3.19v load
The non-branded IMR from COV surprised me, but the others were in line with what I would have guessed. The trustfires hold a charge forever, but they lack some punch. The AW li-on has always been better than I expected it to be... and the AW IMRs have their reputation for a reason.
I guess that's just testimony to the old adage about getting what you pay for... but then, I guess it depends on what you need. Those trustfires I have with a 2.4 ohm atty last for about 3 days and are less than 1/2 the price of the AW li-on which lasts about the same amount of time but delivers a little more punch. I can own 5 trustfires for about the same price as a couple of AWs. That's two weeks + of vaping electricity storage vs 6 days for the same money.

Thanks. I bought a 18650 NoEgo which is a modular unit. In it's current configuration it is a 3.7v. I bought a couple AW IMR 1600mah to use when a VV switch becomes available. In the meantime I wanted to use the AW's in the battery rotation with the two Ultrafire 3000mah I have. Glad to hear it will work just fine.
