Need help picking the best battery for Sub Ohm Vaping

[BuzzKilla]

i bought budget batteries once... will not name the vendor in fear of being pummelled with IM's by said vendor.
the 18350's that i had bought were sworn to be as good as the AW's(by the vendor) , saved $2 per battery.

after discharging all 4 18350's by 4:30pm on my mech. i threw them in the drawer and bought AW's...

Im not saying AW is better than all, but i got shafted with bottom of barrel stuff.
this thread is good research!

There is a value curve with everything. The sweet spot is the part of curve that provides the best ratio of utility per dollar spent. Being an avid flashlight forum guy, I know how group-think can get out of hand and people spending beaucoups of money to get an extra 2-3% utility out of something. It gets ridiculous and borders on the 'keeping up with the Jones' mentality. The OP asked for the 'best of the best' and also asked for the best/dollar spent. I was trying to help with the latter aspect of the post.

That I a agree with 100%.

The flashlight forum doesn't tell the whole story.

They test batteries at a continuous voltage.

The useage on Mechanical Ecigs is bursts of power.
I put my batteries on a flashlight the other day and they worked an hour.
Than took them off and turned it again and they work fine.

Our useage is 1-5 seconds generally with a waiting period in between.

The true test is to put it on a Mechanical with a Volt Meter and see how they do in
bursts.

Yes but if something has a higher continuous output then it will also be accompanied by a higher burst capability, but the maximum output really doesn't effect how long it will work for that is dependent upon the Capacity of the battery

I'm with this guy on this and plus I have always wondered how to spell beaucoups

There's also a value curve on dental and facial reconstructive surgery.

I'm still asking, what's the chemistry there?

i got 4 of these, received in about a week.
i use these with 26awg or lower resistance wire builds.

A battery that is less expensive is not necessarily 'cheap'. Great example are the Panny 185650ch. If you are building 0.5+ ohm coils and follow basic precautions there is nothing to worry about, and you have an extra $10 in your pocket to go pick out a nice juice.

Concerning the Sony 30 amp battery, I received two of them today and proceeded to compare them to the Panasonic 2250 hybrid, here are my results:
Both brands fresh off the charger @ 4.2 volts, the Sony is on it's first cycle, the Panasonics are maybe a month old at the most.
Mod is a box mod that I made from a Vision Eternity box (best part of that deal).
Atomizer Igo-L with 0.5 ohm coil.
The numbers:
Sony .........3.80 volts
Panasonic...3.79 volts
My readings were taken close to the battery so any loss at the switch or socket ect. were eliminated.
Now there was something said about a new battery improving after some initial use, is there any truth to that?
I'll do this test again and put a little more time into it to see how the voltage tapers off with more usage.

So I forgot to leave out some very important information,

I will be Sub Ohm Vaping with Dual Coils..

Does dual coils make a differenece into what battery I should purchase and use for sub ohm vaping?

My understanding is that, with dual coils, each single coil's ohms are cut in half to equal the Total Ohm number.

My question then is, what battery is best for sub ohm vaping with dual coils,


Thanks again guys!

 

[dwcraig1]

One coil or four coils, if say the load is 0.5 ohms it is all the same to the battery.

My results for Sony 30 Amp are different.

I'm taking some of the ambiguity out of this.

I developed a test.

Every 20 seconds I'm firing a battery for 10 seconds on a .65 Ohm Genesis,on a Kamry K100, I record the voltage under load at the end of 10 seconds, At 100 Seconds I take the .65 Genesis Style Tank out and stick the top in Ice Water.
Than do it again.

Using a Tankometer I'm recording the Voltage output under load every 20 seconds. Than at 100 Seconds I'm recording the battery voltage not under load.

I'm going to average the Numbers for every 100 seconds and chart the battery.
I did it last night for a Panasonic 2900 High Drain and will do it for the Panasonic High Drain 2200 and than for the Sony 30 Amp.

I'll post a link to the testing results when done. I believe that this will be a real life test that will indicate which is the best battery for a Mechanical.

Suggestions welcome.

Love that your doing that, Tom Z. If you could see it in yourself to throw a ” classic” into the mix, true joy would ensue. (AW 1600 mah, or MNKE would be great reference points, since that's what many of us may have running)

 

[st0nedpenguin]

The charts already posted show which batteries are best under different loads, there really isn't any need for another, much more time consuming, test.

 

[dwcraig1]

But the new Sony battery and the Panasonic 2900 mah 18650 hybrid are not in the charts.
I agree with pdib, throw in the aw 1600 to compare with as it's the "gold standard"

 

[pdib]

Begging to differ? Don't know til we try? I think draining a battery in bursts may elicit variation in performance.


(tellin' Jesus how it is!)

Exactly, the flashlight forum guys are looking for continuous performance under load.
We are looking for 2-10 second bursts of power and lot's of them.
Totally different way of using the batteries.
Who knows maybe my results will match theirs, or not. I'm convinced the only way to tell is to simulate real world conditions.

I just bought the AW1600 because it's a classic and will give a frame of reference.
Thanks for the suggestion.

Yes it's time consuming, but I watch T.V partially while I'm doing it, otherwise I'd probably go insane. You wouldn't believe how boring and tedious it is.

It doesn't matter if it's a constant drain or intermittent, the battery's ability to put out a given voltage shouldn't change.

If the battery is capable of putting out 4v under load, it's capable of putting out 4v under load.

You could be right, but I doubt it, until tests are done who knows? I'm entering into this with an open mind. I'm not trying to prove a concept. I just want to find the best battery to use in a Mechanical by using an actual mechanical and simulating real world usage.

It is possible that different batteries have different resistance levels and are capable of pushing out more voltage for a short time than other batteries. For example the Sony is rated to put out 30 Amps burst, the Panasonics are 10 amps continuous and 16 amps burst.

The A & W 1600 is supposed to be so good because it has a lower resistance. There are a lot of questions unanswered.

Let me state why I have my doubts, it's hazy but I put an 18650 MAH batteries into a Flashlight after an hour it couldn't put out enough energy to power the flashlight. I took the battery out for a minute or two. The battery recovered and powered the flashlight for more time.

So we have discharge and we have recovery. This made me think, the Flashlight guys are measuring batteries under constant load with no recovery time. We on the other hand are pushing out huge Amps and Volts for 10 seconds than giving the battery time to recover. It just seems that our usage is totally different.

If I had all the time in the world I should probably be doing 10 Second every 15 minutes!

 

[pdib]

Yep. Yep. Yep. And what we are looking at is, what can a battery deliver for a few seconds when its ten percent depleted. I don't care if it will keep a VV running til I get home from work. I wanna know if it can dump a 10 amp toot.

If the battery is capable of putting out 4v under load, it's capable of putting out 4v under load.

So when he's done and posts the results, don't look. Problem solved.

Seriously - his results will either replicate the results from other tests with different parameters, or they won't. Either way, something is learned. It's odd that anyone would be opposed to someone essentially performing free research...

 

[niczgreat]

Hi all would like some advise. What we really want to know is how long the batteries will last in the Mecanical RBA vaping range. The lower I go the more work. I tested the battery all the way down to 2.75 but for simplification and ease, I was thinking that the cutoff for good vaping on my chart at .63hm should be at around 3.2V. I don't think anyone on a mechanical and RBA would want to do below 16 Watts? What do you think? Or should I make it 3.0 Which is 14.28 Watts?
Any votes?

My premise is that I don't give a hoot how long the battery lasts, only how long it stays in the Zone. So what do you think the bottom of the Zone should be?
