Imediate help with batteries needed :)

[paumit]

Hi guys,

looking for some awailable batteries in my region and seems i cant find aw, mnke or other most popular batteries for mechanical mods curently using nemesis clone mod with nimbus atty in range of 0.2-0.6 ohm and the batterie i got was ordered from uk aw imr, but delivery take very long. So i'm looking at these ones with specs:


1. 18650 3.7V 1500mAh Li-Ion SANYO UR18650W2
Ø18,25x65mm, 3.7V, 1500mAh, Li-Ion, SANYO, UR18650W2, padidinta iškrovimo srovė (increased discharge rate) if I translated it well from my native.

2. 3.7V 2600mAh Li-Ion PCB SANYO MR18650
Ø18,25x69.9mm, 3.7V, 2600mAh, Li-Ion; with PCB 2600mAh; MR18650,47g
direct link: LEMONA electronics - Elektronikos dalys

3. 18650 3.7V 3100mAh Li-Ion Panasonic NCR18650A
18650 3.7V 3100mAh Li-Ion Panasonic NCR18650A (there is notification that says do not use this battery without safety scheme)
direct link: LEMONA electronics - Elektronikos dalys

So could i use any of them in my mod at the mentioned ohm builds? I do not have very heavy vaping sessions so not pushing limits of battery, but dont wanna be doing that in danger.

Thanks.

First, I'm not a battery expert by any stretch. Second, I'm not familiar with any of these batteries. The last two I'm assuming are not "high drain" based solely on the mAh ratings. (Too be honest, unfamiliar batteries make me very nervous)

Saying that, and with some degree of trepidation... assuming its a genuine Sanyo battery and not a forgery, only the Sanyo UR18650W2 might be considered a "high drain" battery - rated at 15a max current (the only listing I can find), and probably suitable for modest sub-ohm use.

To be safe, I'd refrain from builds below 0.5Ω ~ 0.6Ω. Use this calculator and enter your resistance and voltage... and you'll see what I mean - at 0.3Ω and 4.2v, you're at 14 amps drain. I would not want to push an unknown battery too far. Get a vapesafe or similar fuse please... and be careful. ;-)

I am not familiar with the first battery.

The second battery I can say with confidence that it is an absolute NO GO. This battery has a maximum discharge rate of 2.5 amps. Not meant for vaping whatsoever.

According to this, the protection of the third battery will trip at 6.2 amps....

So the answer you are looking for is NO, these batteries are not for you.

For what you want to do with them try to find one of these 2 batteries:

Sony hybrid

us18650vct3 1600mAh 30A
us18650vtc4 2100 mAh 30A

I would strongly advise against building a 0.2 ohm coil....

A setup like this will pump 21 amps out of your battery... While the sony batteries that I mentionned above can take that, if your coil, for some reason (and it can happen) loose 0.1 ohm, you will end up pumping 42 amp out of your battery, and that... No batterry can take.

Would Sony US18650VT1 go as well ? Sony 1100mAh 4.1Wh Li-Ion 3.7V 18x65mm was the only one i could find in my country

Get a regulated mod, or the proper batteries before you blow your mod up.

Regular Li-Ion batteries can't take the amp drain....they get hot and vent/flame/blow. If you can't find high-drain IMR batteries...don't do what you are doing.

I'd rather see you get a A/C to USB adapter that supports 2 or 3 amps....and build a 5 volt "passthrough" e-cig. Wind a 3.0 ish ohm coil and vape away. See the modder's section. Do it safely.

I hawe 1 proper one AW IMR 2000 but its already loosing its power ;/ charges only to 4.1 not 4.2 as it should and drains realy quick half a day or so ..

 

[AttyPops]

Well, you could try upping the ohms a bit to increase battery life...and if you use thinner wire (assuming you can get kanthal wire there) you can up the ohms even more. The thick wire requires a lot of watts to work.

So...basically, buy time for the proper batteries to be shipped.

The discharge rate of the AW IMR that you are using is 10 A. This is not the right battery for what you are asking of it. It is pulling 21 amps with a 0.2 ohm coil. Check this page out.

Your AW will not last when you abuse it like that. Get you some of the AW IMR 1600's, they have a discharge rate of 24 amps. Or one of the other batteries listed there that list at a higher CDR (Continuous Discharge Rating) Much more suitable for what you are doing.

Cloud Chasing is Dangerous

How is Sub-Ohm Vaping Dangereous?


Anyone who uses sub-ohm coils without the proper batteries is a fool. 0.2 ohm coils is just plain crazy - you are only 0.2 ohms away from a hard shorted battery. I don't know who your mentor is but they have no regard for your safety. If you can't find the right batteries you have no business doing sub-ohm.

Unless you know the battery's amp limit in continuous discharge rate, you don't know if it will be safe for sub ohm. Anyone who does sub-ohms less than 0.8 ohm needs a battery which has over 10 amp CDR.

Battery Basics for Mods

NONE of the batteries from the supplier you linked to are fit for sub-ohm vaping. You will either have to find another vendor who does carry them or discontinue doing sub-ohms altogether. You can see the effects of a battery that goes into thermal runaway below.

Nothing to add that hasn't already been said.
That low of an ohm (resistance) is getting really dangerous.
Trust us on this. I just shipped my prize Reo Grand back to redeyedancer because I managed to melt the 510 insulting gasket. As soon as I got a reply from him, i pulled the battery and got her ready for shipment.
I ain't taking any chances.

Hello folks. got 18650 3.7V 1500mAh Li-Ion SANYO UR18650W2 and only use in nemesis and lowest ohm will be 0,7-1,2, so its good in regards of ampers. but what if short circuit happens? and one more question is short fuse will protect me from any battery damage and is it gona limit my ohm choise?

 

[Baditude]

I assume you're talking about a Vape Safe fuse. They generally will trip with any amp over 7 amps. Some fuses are single use, some are multiple use - it depends upon the fuse you purchase. Keep your coil at 0.7 ohm (6 amp continuous discharge rate draw) or above and you should be able to avoid tripping the fuse.

15 amps continuous discharge rate is enough for a 0.7 ohm or above coil.
