Is it true for sub ohm build, it's better to use low mah (~1800) than high mah (~2500)?
Sub ohm coils require an IMR high drain type battery which can put out a high continuous amp capacity. The 18650 MNKE 1500 mAh IMR has a 30 amp capacity* and the 18650 AW 1600 mAh IMR has a 20 amp capacity*. Other IMR batteries may only have a 10 amp capacity.

AW IMR 18650 1600 mAh

"If you’re into those ultra low resistance coils (which I don’t recommend BTW – I personally believe .8 ohms and up should be PLENTY good enough) KNOW YOUR BATTERY!!! Be sure that the battery is capable and rated to generate the amount of amps required by your setup! For example:
Setup 1 = 1 ohm coil with a loaded voltage of 4.0V (just an example). Using Ohms law, Amps = Voltage/Resistance = 4 Amp Draw. Easy for most batteries!
Setup 2 = .3 ohm coil (which I DO NOT recommend) with a loaded voltage of 4.0V (again, just an example). Using Ohms law, Amps = Voltage/Resistance = 13.3 Amp Draw. Can your battery support that?"

I would recommend you to get an AW 1600 mah battery for your first subohm battery. Make sure it's the 18650 1600mah. Later as you get into it more you might look into other batteries but that one is a great one to start with and competes with the best even today.
If you're asking these kind of questions you need to spend more time reading up on the subject before you start blindly tinkering.
Casting my vote for the MNKE IMR18650.
Has a higher C rating than most AWs I've seen. I made a post last week explaining C rating and whatnot. Here's the excerpt from it:
Just gotta find the C rating for whichever battery you're interested in and you can decide for yourself
Just make sure its IMR, not ICR. IMR = safe chemistry, harder to combust.
EDIT: Of course the higher C rating on the MNKE is at the cost of a lower mAh. Worth it IMO for a safer vape on subohm coils

From the results I've seen, there's no reason to go with MNKE:
High-Drain 18650 Shootout
High-Drain 18650 Shootout
Yeah, so, I loved using my MNKEs; but I gotta make a correction on two of the above posts.
MNKE max. cont. discharge is 20 amps, not 30
AW1600 is 24 amps, not 20 (C rating here is 15)
Both perform great; but you'll want the button top (AW) for when you get your REO Grand

Sorry for posting inaccurate info (?). I guess I'm confused about which amp discharge spec is most relevant to our purposes. According to RTD Vapor, the MNKE has four specs listed for amperage discharge:
Maximum Continuous Discharging Current 20 A
Maximum pulse Discharging Current 60 A
Maximum Continuous Charging Current 6.5 A
Maximum Rated Discharging Current 30 A
-- Batteries : MNKE IMR 18650
So I take the maximum continuous discharge stat is the one we should be most interested in?

Ya, that is confusing! I think of the MNKE as 20 A batts very similar to the AW 1600's with a lot in reserve for pulses. I do think they have less voltage drop than the AW's but I can not give you any data to support that.
Too bad.. You don't know what you're missing. I like tube mods myself, but the REO is in a class of it's own...

You may be right, Baditude. I hadn't seen that spec. type before. Other batteries I've looked at specs for are using the Max. Cont. category; so, I was doing an "apples-to-apples" thing without consciously deciding.
FWIW, I've used both MNKE and AW @ 0.5Ω, and (for all practical purposes) they are both great. Although (and I don't know why, maybe because they're not tested with burst discharging) the AW1600 always chart substantially better.
Could someone give this new member a hand? I have to go out and do some things today...

Is rtdvapor.com reputable vendor for batteries? Any other vendors I can order batteries from? Feel sketchy about buying from ebay. Thanks
