Can i use these in a sentinel v3 with igo l and a .5 ohm coil and be safe? Also do these fit into mechs or do you specifically need 18650? Batteries : MNKE IMR 26650

No, those will be too fat to fit in the V3. The #s are measurements, 18650 is 18mm wide and 650mm long (I think). 26650 is as long as a 18650, but wider.

Are panasonic CGR18650CH unprotected batteries that are safe to use in a mech mod? I have them from when i bought my vamo. Are they as safe as imr? I also wondering about aw imr 18650 2000 mah from rtdvapor. Is this the battery of choice for mechanicals? I want to buy the most frequently used battery by vapors who do subohm coils but are really safety concious.
Hiya, Rader! I just bought 4 of those. They're having their initial charge as we speak. These certainly do chart out nicely! As far as I've found, the only battery in it's class (sony US, AW1600, MNKE) with 2000mAh. Excited to try them on my auto fuse modded REO. I was getting 0.13V drop on a 1Ω coil with the AWs. Hoping to see . . .. . IDK . . . I'd cream my pants for a straight 0.10V! (but 0.12 would suffice)

IMR (Lithium-Managanese) packs less power in the same volume than most other Lithium-based chemistries, so you won't find huge capacity IMR batteries; I think they stay below 2300 mAh, currently.
Usually lower capacity IMR batteries sport better continuous discharge (C) rating, though.. so it may pay off buying for instance an AW 1600 mAh or MNKE 1500 mAh than say an AW 2000 mAh. It's always a trade-off, I guess
If you're going to use a mech, I'd only recommend IMR batteries; if you use a mod with regulated voltage (and built-in protections!), on the other hand, any chemistry capable of that continuous A drain will be fine.

Xpen or anyone else are the Mnke Imr 18650 1500 mah going to be better for performance and equal in safety to the Aw imr 18650 2000 mah , Aw imr 18650 1600 mah or Aw 18650 imr 1500 mah. Can someone explain what the benefits of lower mah batteries are vs higher mah. Whats the trade off? Lastly do most mech mods use flat or button top batteries? Thank you for helping me step into this confusing topic.
Jay don't take this wrong but I'm under the impression that you should research this subject matter a bit more, before venturing into the mech world... This thread alone already contains more info than you can apparently digest, I'd say just about anything you were (and still are) asking for
Do yourself a favor: take your time with this.. research a bit more into batteries, Ohm's law (and its consequences), and mech mods.

No worries I agree actually but I am just trying to double check what I know and make sure I'm not making mistakes. This is what I know so far about using ohms law and avoiding the consequences. Correct me if I'm wrong but my best bet would be the aw imr 18650 2000 mah because at .9 ohms id be around 4.66667 amps and 10 amps is the continuous discharge rate. The 2000 mah is also better for me because it allows me to stay in my sweetspot longer. If I wanted to go a lot lower than .9 ohms it would be safer to go with the Mnke imr 18650 1500 mah because it has 20 amps of continuous discharge rate.
At 5A discharge there's practically no performance difference between the AW (IMR 18650) 1600mAh and 2000mAh, but if you go beyond that the 1600 wins by a good margin in the zone you're most interested into as a mech user: 4.2V to 3.7V
Have a look here: http://lygte-info.dk/review/batteries2012/Common18650comparator.php
Choose the two AW batteries from the list and select only the 5A and 10A checkboxes, and look at their discharge curves.
All in all for a mech I'd probably buy the 1600's..
There's plenty of good threads about sub-ohm vaping on ECF, but don't miss this one: http://www.e-cigarette-forum.com/forum/showthread.php?t=465483
Enjoy!

Well thank you still! Besides I like to triple check with info like this. Thanks Xpen.
Yes, the Samsung INR18650's are safe chemistry. I'm not sure what you mean by the bold sentences, as the battery I recommended IS >10A discharge and holds over 1900mAh @ a 20A discharge rate.
CGR/CH's are great batteries in the 10A discharge class. I used them exclusively until I retired them after over a year of use (~6months of that was @ .5Ω) Impeccable safety record.
Lower mAh is typically a trade off for higher discharge rates. It's mostly about the chemistry, but the condensed version is that high discharge chemistry has a lower energy density than high mAh/low discharge chemistry. Although cutting edge battery tech is breaking that trend...like Samsung's yet to be released INR18650-25R with 2500mAh and a 20A CDR.
Dont be fooled by the mAh. 2000mAh sure sounds better than 1600mAh, but how much of it is usable? A typical mech user wont vape much lower than ~3.6v. Take a look at the comparator that xpen linked and select the two AW IMRs and the 5A curve. If you change your battery out @ 3.5V under load (3.6v-3.7v open circuit voltage) then you have a USEABLE capacity of only 750mAh with the AW 2000Mah versus a USEABLE capacity of ~1000mAh with the AW 1600mAh. Also notice that the 1600 holds a higher voltage throughout the curve than the 2000.
Now, in the comparator, select the select INR18650-20R and compare it's curve to the AW 1600.
Either one will be a fine choice for nearly any use with a mech mod.I have been very impressed by them. In use for about a month now and ZERO complaints. I havent done any comparative measurements mainly because the only thing I have to compare to are some well used CGR/CH's....and the fact that I havent had the time or will to give all the brass contacts a good patina-free cleaning to get a good measurement.
Are fasttech samsung inr18650 20R 2000 mah authentic? Im considering them or buying from ebay. Anyone have a trusted vendor? Or is Ft ok?
Sorry no clues got mine off ebay (Europe). They do work and look genuine, but hell who knows...
Get the Sony 18650 has 30a output. Best battery on the market. Will handle anything you can build and throw at it. They sell them on bevapehappy.com
