Battery options

[eHuman]

AW IMR 18650 2000mAh?
AW IMR 18650 1600mAh?
Panasonic High Drain NCR18650PD?
Orbtronics?

I don't intend to subΩ vape but because I target 1Ω it is possible.

Which batteries give the best combination of punch and longevity? And who has the best prices on them currently?

P.S. My copper vein grand/brass RM2 arrives tomorrow, convenient as I don't have any classes on Fridays. (Squeal!)

EDIT: These work good? http://www.amazon.com/4pcs-Panasonic-CGR18650CH-Li-ion-Battery/dp/B00AKQQ990

Sorry, no answer, only more questions...
Concerning the 18490, are there any viable (sub ohm) options besides AW IMR? (With which I don't dare going too low)

 

[Raynman]

The Reo was designed to run aw 18650. The ones you pointed out are flat tops and will not work well. That being said I run Orbtronics and efest but plan on getting aw's asap.

The AW IMR 1600mAh is the tried and true workhorse for this mod. That's your safest bet for reliable performance and lowest internal resistance (32 mΩ . . . . I think). those will give you good kick down to 3.8V. The 2000s tend to sag from the get-go (IMHO).

If I were in a devil-may-care mood and wanted to try something else . . . it would be the Samsung INR 18650-20R (2000mAh) Those things chart like candy.

The AW IMRs are the recommended battery and all I use, but no matter what you end up with, you should definitely make sure they are button top. The flat top batteries will put undue stress on the firing pin for sure.

I think they're flat tops. But they do look very sweet.

All I've run in the Grand are the AW 1600s. At about 1 - 1.2 ohm they preform well and will last me all day.

Vendor contacted me informing of an error, that they do not stock the 1600s.

Back on the hunt for batteries.

eHuman,

for no sub-ohms the ncr18650pd will last you a looong time, even with sub-ohms they last time most of the day (the PD are 10Amp so I don't use anything lower than .6 ohm on those)

the cgr18650ch are also a good choice, you can get 4x of those off amazon for some $30 shipped

I believe the Orbtronics are based on PD cell

And the AWs are said to use Panasonic cells as well. At least for some of their runs (this is what I read from the RBA sub-forum, I don't use AWs myself)

If you ever go sub-ohm the best one performance-wise 9although they last significantly less) are the Sonys 10Amps

also ordered a new model from Panasonic, those are 18650 IMR 15 amps, but I don't have them with me yet so I couldn't tell how you how good or bad they are.

trying to learn something here:

eHuman, why wouldn't you get the 2000mAh batteries ?

JC Okie, and why/how would 'flat tops' stress or make a difference (never understood that)

thanx guys

 

[pdib]

Well . . . . . flat tops . . .. . bad, yes. No argument. I know from experience. (although I was using Ox-Gard instead of Noalox at the same time . . . . . . . . )

Anyway, now that I'm configuring/making my own firing pins, I though I might revisit this question. Crazy? Kooky? Wacky? FUN?

The 1600 mAh have a higher C rating than the 2000s, but for 1 ohm and above I'd rather go with the 2000maH

With the flat tops you would need to push the button further down for full contact. I soldered my own button at the tops for all my batteries and have no problems with it.

With the exception of one person, everyone who has tried both (whom I've talked to) has found that the 1600s kick like a mule from the 4.15-3.85 volt range (mech. user's range). This is more apparent on subΩ coils, but applies to 1Ω as well. The 2000 have much higher internal resistance and start to sag from the 3rd toot. I usually end up swapping out a 2000 at about 3.95V because it feels too weak; whereas a 1600 has almost no discernable difference down to 3.84V, for me.

A number of us were bringing our high drain flat buttontop batteries with us when we bought our REOs. We had lots of problems with arcing to the fining pin, oxidization, anemic performance and misfires. This could be attributed to: flat button tops and firing pin travel, worn battery terminal surfaces, high amp draw (and in my case, Ox-Gard) - - - or any combination of these factors. The button tops seem to perform much better. The firing pin is designed around a battery where the button sits up in it's delrin slot, and the firing pin then has less travel and less angle of attack. also, pushing the pin twice as far, literally stresses the metal more over time (but I haven't had a pin "wear out" on my yet).

I, for one, have had minimal (almost no) problems with arcing since I started with a fresh set of AW button tops. the only other thing I've changed is my Noalox. (and I do think that is secondary)

My sony's are flat tops they work but if your not subΩ vaping just go w/ the 1600mah AW IMR's.

 

[pufZeppelin]

OK, I believe I understand that--but dare I ask: what is OX-Gard and Noalox ?
I know Noalox as being an 'anti-corrosive'

The sony's sound good! I've seen charts tho, where the Aw 1600s outperform them. Don't underestimate these little hummers. The have a max. continuous discharge of 24amps. Basically, triple the amp rating of a .5Ω coil. Bishopheals switches out TO the AW 1600s when he goes below .4Ω (I just use them for everything)

Noalox is the recommended anti-oxidant for the firing pin tip on the mech. REOs. It greatly reduces sparking and oxidation. Ox-Gard is a product for similar industrial applications; but it's composition is different, and I have found it to work against me with this application.

Fwiw, I purchased 4 AW IMR 1600 mah batteries in the fall of 2010. I bought 4 more in September of 2011. I shuffle them through my 2 Grands and my Woodvil daily. I don't run them down excessively but re-charge relentlessly. All 8 are still in service and serve me well. I don't know how many hundred cycles they've been through but many. They are the way to go.

I just got hold of some MNKEs i have been promising myself i'll try. I often go subΩ with my coils. They are flat tops too - but i have other mods that use magnets on top of the battery and so shall these.

The AWs are good and my Orbtronic ones have been great.

What about 18490, anybody can recommend anything besides AW IMR?
To be frank, I'm tired of the red color. (Yes I know that is stupid).
And about low ohms...
I can do the math as long as I'm right that it's voltage under load that should be used to calculate amps / battery safety. Am I?
I suppose the AW IMR is 8C(low estimate, I've seen 10 even 15?!), then 8.8 amps. A 0,5 ohm coil with, say, 3.5 volts under load, would be 7 amps. Is that so? That would be close. I don't want to go as far. I'd like some room before explosion lol.
Anyway... Any better batteries for this? (Feel like experimenting, happy anyway with my 0.9 ohm ATM)
