My Batteries Questions

[Meltz]

Ok so the two batteries i have are

AW imr 18650 3.7V 2000mah(7.4wh)

and

efest imr 18650 3.7v LI-MN 2500mah 35A

My question- Are they both safe to sub OHM on?

Also is there some sort of cvhart out there telling which batteries are good at what OHMs?

I just build a duel coil .23 OHM on my magma but i just want to be sure its safe to use because its hitting like a champ but it is abit warm.
Just want to be safe and i know you guys here are very smart about this stuff =-)

Do you know how many amps your build is pulling?

 

[jagstownville]

I have been building most of my coils around .30 (I've yet to go lower) but use sony 2600 batts mostly, but have also used the same efest without any issues. Don't have any warming either.

I know for sure the AW battery is NOT. I have that battery and when I asked a local shop to build my coil for me, he said not to sub ohm with it, that I would need to get a different battery.

AW IMR 18650 2000mAh. *NOT SAFE* for your build.

If you have a Purple EFest 35 amp. It is safe to run a 0.23ohm coil. Though it's still an EFest which aren't as safe as a Sony VTC4 or VTC5.

FYI -- The Purple EFest 35A batteries are only 20A continuous.

the 35 amp rating on those purple e fests is actually a pulse rating, and nobody really knows what "pulse" indicates as far as a measurement of time. Not advisable for really low sub ohm vaping.

yes. Find some AUTHENTIC Sony's. With them being snatched up as soon as they get to the market there are a TON of fakes/rewraps out there.

His coil as he originally wrote would hit at 18.3 amps on a fresh battery at 4.2 volts.

As I said it is safe, but it's still not a Sony.

 

[Meltz]

so where can i find some authentic sony vtc4 from online?

 

[Griff.J]

I honestly don't know sorry. I've never looked to buy Sony VTCs, I only use AW IMRs as I don't sub-ohm and generally use Evolv regulated devices (Kicks in my mechanicals, or DNA devices). Perhaps someone here knows of a reputable store who stocks them.

Also Sony VTC5 is the latest version with the highest mAh rating and Amp limit.

wow just realized they are 100 bucks =-( Anything cheeper that is close to there safety?

$100 for a battery? Where are you looking?!?

**DELETED**


Edit: Posted a link to an LG battery I saw. But it's only a 20amp like the EFest.

Edit 2: Some people quote too quickly. now I can't get away with deleting this info..

 

[Kaezziel]

Just checked and the usual goto rtdvapor.com is still out of stock on VTC4s and 5s...

 

[Kaezziel]

Like another has said they're usually out of stock everywhere. I just noticed this:

LG 18650HE2 2500MAH 35AMP

At one of the stores K702 posted above. This should be a high quality battery as well, I'm sure someone will correct me if i'm wrong though.

Decent battery, but if I'm not mistaken, it is a 20A continuous as well...

 

[Meltz]

how are the MNKE 30A/60A IMR 26650 Batteries ? are the safe like the sony vtc4 ?

 

[Kaezziel]

Check my blog entry... that's the best 26650 I've been able to find, and even it isn't a true 50A battery... I've found nothing about the 30A/60A MNKEs that you're referring to...

 

[Griff.J]

26650 batteries are 26mm wide. they won't fit in a device meant for 18mm (18650) wide batteries. But yes MNKE are high quality batteries assuming you get the right sized one.

Battery number code:

AABBO (example 18650)

AA = Battery Diameter in millimeters
BB = Battery Length in millimeters
O = Battery Shape. 0 means, Round.

So 18650:
18mm in Diameter
65mm in Length
and 0, it's round.

(At least this was what I learned back when I started vaping).

COUGH* wheres Baditude? COUGH*

thanks so the MNKE 30A/60A IMR 26650 Batteries wont fit in my panzer! Ill have to find the sony 18650 30 amp vtc4 then =-)
