18350 sub ohm

[Strontium]

You should try Orbtronic sx22 (18650), it beats Sonys at high amps pretty badly.

No Thanks ill stick with what im using see no reason to downgrade.

that is still what i consider "in the danger zone". like stated before. you only want to push 50% of the amp limit. meaning. you wouldnt want to push more than 1.0 ohm through a battery with an 8amp limit. this will give you the best lifetime of the battery and not stress it as well as keep you safe from a venting battery. i cant tell you what to do. but when/if something goes wrong. we all told you that, that was not safe.

50% of the amp limit You mean 100% of the CDR? Because that's generally how it works out. Pulse limit (10 second burst) is usually about twice the CDR. That said, 5-10 second pulls at near the CDR are perfectly safe. I would restrict Pulse limit pulls to 3 seconds. This only applies to quality, high-drain batteries, like AW's, Sony's, and the like. I'm all about battery safety, but I'm also about correct information. Using an 18490 at it's maximum continuous discharge rate puts it on the verge of pulse discharge rating. Moderate the length of your pull. If your battery gets any more than a little over room temperature, you'll want to consider raising your resistance a bit.

I know what I am talking about. Sony can print 30A, but in reality it is not that good.
Orbtronics SX22 would be an upgrade from Sony.

This is 22 amp. const. current test SX22 is "killing" Sony in both fields (capacity & voltage sag ).




Some manufacturers are better than others, only tests will show battery performance and claimed rating.

SX22 will hold its capacity at 5Amps, and the same at 22Amps. Sony's capacity will drop. Maybe in future they make something better.

yes 15c.

IMR18490 Specifications :

Nominal Voltage : 3.7V
Capacity : 1100mAH
Lowest Discharge Voltage : 2.50V
Standard Charge : CC/CV ( max. charging rate 3A )
Cycle Life : > 500 cycles
Max. continuous discharge rate : 15C
Operating Discharge Temperature : -10 - 60 Degree Celsius

15.c = 16.5 amps continuous

taken from AW dealer

IMR16340 / IMR14500 / IMR18350 / IMR18490 / IMR18650 / IMR26500 *Part 2*

Not that I question their specs, but I question their specs.

Lowest Discharge Voltage : 2.50V
Standard Charge : CC/CV ( max. charging rate 2A )
Cycle Life : > 500 cycles
Max. continuous discharge rate : 10A
Operating Discharge Temperature : -10 - 60 Degree Celsius

So their trying to tell us that an 18490 outperforms an 18650.

Your questions are good.

AW 18490 is unusable at 15C
AW 18650 (2000 mah battery) unusable even at 10 amps (performance very poor)

 

[Emtpeters]

If I'm using anything lower than 1 ohm I only use an mmke 18650

Wow, was constantly vaping on 18350 while viewing this thread, guess ill have to switch to 18490. thanks alot people!

Considering there were only 4 posts by the time you put that up I fail to see your smarmy point. Oh yeah - I do. If you were expecting something less than credible advice on this one you came to the wrong place.

I don't see any problem here. He was unknowingly using an 18350 battery unsafely for sub-ohm vaping, asked about it getting warm with his coils, was told that 18350's aren't suitable for sub-ohm vaping and doing so is very dangerous, and stopped the unsafe behavior almost immediately (just 14 minutes after his initial post). He also thanked those who responded for their advice.

Plain and simple.
DO NOT use 18350 for subohms.

I've been using 18490 aw for sub ohms .6 -.8 for a couple of months with no issues

I have seen guys smoking an analog cigarette while pumping their gas. Nothing happened

as it been said a couple post up those aw18490s are supposed to be 15c
I'm wasn't trying to be a smart*ss but is this info correct or not?

Well I just learned something thanks guys

From what i understand and what i've heard/read, these two cells have different guts (to put it simply). The 18490 referenced above is the shorter version of AW's 1600 mAh 1860 (not the 2000 mAh). Both have max continuous discharge rates of 15C.
