Efest verses AW test

heliguyheliguy

I am going to compare efest to aw tonight just to see if there is a performance differance.
I would normally use 4 efest batteries on a night shift but I got some AW today so I want to see how they hold up since they cost twice the price.

Test equipment
Efest 18350 800mah
Aw 18350 700mah
Evic in mini mode
Kanger t3 (home coiled)
Resistance 1.5ohms (0.20mm kanthal)
E-liquid Grants vinnilla custard 50/50 12mg

Method
I will run each battery until the device powers itself off due to low power.
I will use the same atomizer through out the test.
I will reset the puff counter at each battery change and record the total puff's.
I will record the time taken to deplete each battery.
Wattage set at 9 watts for duration, unless vape is affected any change will be noted.


Any suggestions?

Test started at 6:30 with Aw battery
currently @ 45 puffs and 69% remaining (according to evic)
while with this setup 9 watts is my goto setting I'm finding it a bit harsh with the aw.
So I have reduced it to 8.5 watts.

how long have you had the batteries? they can take several cycles before coming into their own i think

just got the aw today.
I got the efest in late December.
I can run it again in a few days, to compare.
it would be interesting to verify that either way.

heliguyheliguy

Still a bit harsh, so I have dropped again to 8 watts.
Its early days but it seems the aw may be delivering more power at the coil???

heliguyheliguy

ok first battery (aw) depleted @ 22:52 154 puff's, it went all the way down to 2% on the evic display then I got the power low warning.
this is unusual as with the efest it turns off at around 20%ish normally.

anyway the efest battery is in there now and the puff counter has been reset, lets see how it goes
still vaping at 8 watts for now.

Well, well come on what's the latest, or have you been sneeking a quick 40 winks on the job

And they say a Disposable Ecig with a 350 mah will give you 300+ puffs :rolleyes:

I wish

Efest died at 2:04 104 puffs 20% on evic
A definite drop off in performance for the last 10 or so puffs.

I am getting 460 + puffs (8 seconds each) with my 3100 mAh panasonic 18650. 2 batteries.
420(ish) with my panasonic 2600 mAh 18650. 1 that came with eVic
360(ish) with my 18650 I bought for the lavatube yonks ago, not sure what mAh they are. 3 batteries.
Go for the bigger batteries Double H you can vape yourself stupid on them

heliguyheliguy

I have the bigger batteries, loads of them.
I like the dinky size of the evic & 18350.

heliguyheliguy

2nd aw dead at 7:56 155 puffs @1%
a performer to the last

heliguyheliguy

2nd efest dead @ 11:03 @ 128 puffs 17% displayed on evic.
again with performance drop at end!

heliguyheliguy

In conclusion aw is the better battery.
In fact 33% better; is it worth twice the price, you decide!
Also the vape is consistent to the end with aw battery.
The main difference is in that last 20%, the aw which carries on but the efest while still showing the voltage can't deliver the current and so shuts down.

Sir Digby Chicken Caesar

just realised there now, i've noticed something similar with my efest 18350's

i've checked the voltage and it's been at 3.5 or maybe 3.4.. and then the provari would cut out a half hour later, no way i'd have used up enough voltage to drain it down to 3.2v in that time

might grab some aw's and see although with the price of the efest's it's not that big a deal considering I can stick 4 of them in my pocket easily

heliguyheliguy

The problem is now I know the vape is better with the aw's the efests a bugging me. The aw's seems to give up their electrons with ease

I've just noticed on my vamo that there's a big drop off in performance when the efest battery is at 3.6 or even 3.7 volts. Just swapped out a battery with 3.6 volts left for a fully charged one and the difference is very noticeable (vaping a 2.8ohm carto at 11.5W).

They only charge to 4.2 volts using a trustfire charger, is this normal? So with a 18650 battery you only get 0.5 volts, I only vape in the evenings so I'm still getting 2-3 days out of a charge but still doesn't seem that much. Do they improve after a few cycles? I've only had them for about 10 days or so.

Mr. Chrome

Great test heliguy, I find my 6 month old lavatube batteries outperform my new efast ones and the 350 efast seem to drop .1 volt every time i take a few drags! I'm vaping a 2.5ohm dct tank at 8.5 watts.

Yup. That's ideal.

Not sure what "only get 0.5 volts" means.
4.2v=fully charged, then it quickly drops and stays delivering 3.7v for the majority of the time, then droops down slowly before something (mod/protection) stops pulling power from it.
Handy calculator to see what your battery life should kind of be like in use, 'cos you say you only use it in the evenings, but I have no idea what battery or how many hours are in your evening.
If you're using it for 6 hours a night and pounding it with, say, a 2000mAh battery, 3 evenings is really good.

They do - judging from tests online, usually between 5-15% increase in mAh. Not gonna be a huge difference.

heliguyheliguy

Just to be clear I think the efest are an excellent battery much better than most of the crap on ebay, the test just showed that the aw's are indeed better.

I probably do get 2-3 evenings but I reckon I'd use a full battery in a night easily if I was out drinking for a good while or whatever.

My main issue is that it drops to 3.7V fairly quickly as you say but I don't think it delivers as much power when it hits 3.7V compared to a fully charged battery, not @ 11W anyway. Which I find I need with a 2.8 ohm resistance cartomiser.

I did get 2 batteries so I suppose I can just keep swapping them around. Is there any negative impact from charging them once they hit 3.6-3.7V? Or should I try to fully discharge them every once in awhile?

Sir Digby Chicken Caesar

it's better for the battery lifespan to be charged around 3.6-3.7v, fully discharging them lessens their ... lifespan

also i noticed the same thing in my lavatube once the battery dropped around 3.6v, if you increase the voltatge your vamo is set at.. it will still drop but it will drop to a voltage closer to what you had it set to originally.. if you follow me. this will drain it even faster though

no negative impact with li battery, they seem to last a couple of years as long as you don't exceed the min/max limits or over heat.

I tried putting it right up to 15W just to see and the vape was the same as when it was at 10W, this was when the battery was down at 3.5V. 15W with a new battery would not taste good. So it just can't supply that much current when the battery is low. Ideally it would just tell you the max Volts/Watts it can supply but I guess that's asking for a bit much.

Sir Digby Chicken Caesar

it's possible, but it's expensive

the provari gives the voltage you set right up to the moment the battery is drained. afaik it's the only one that does and it's also quite a bit more expensive than the rest because of the electronics inside

well also because you can make a fancy pants product, slap a huge price tag on it and people will buy it just because.

I'm not that pushed to be honest, so far I'm pretty happy with the Vamo for the price. Finish is holding up well so far despite numerous spillages.

You'll find that the AW's will have more charge cycles over time than the Efests.
The Efests are good value for money all the same.

Anybody ever use the vmax batteries?

Curious about the Panasonic. Did you get that from Batterycity.ie? Was just googling them, I want to get them as quick as possible, so looking for an irish source. €13 each if you buy two off that site, doesnt sound too bad.

And can you get flat tops of those? My evic doesnt get on very well with my button top efest 18650. Problem is i would like them for other mods too, bleh!

No I got them from e-cigshop.eu @ €12.95 each (flat top), bought 2 of them, plus the one that came with the eVic (Panasonic) and I had 3 batteries from the Lavatube, so got 6 batteries for the eVic all flat top.

Brilliant. I completely forgot that shop existed. Thank you

Would be interesting to see how the Pink Evic Battery Compares

rickyjb

Just noticed that one of my efest batteries only works intermittently in my vamo. Wrecked my head all day yesterday as I thought I had my RDA set up wrong. Figured out what was happening today and tried a twist battery which gave a consistent draw, then tried another efest battery which was also fine.

Anybody come across this or any idea what's causing it, just a faulty battery?

Green Hornet

Gonna buy a couple of 18350's for my evic and was googling efest vs aw when this thread popped up....

The efest that I bought last week with the 18350 tube shuts down the evic at 30% remaining, plus I got a nipple top instead of a flat top......The efest always seems to end up giving a high temp warning on the evic as well for some reason but the 18650 never gives this warning?

So, I assume I should buy a couple of 18350 AW flat top batteries rather than efest. They'll actually work for much longer in the evic as they will run down further before shutting it down?

heliguyheliguy

That's what I found in the side by side test.
I now stick to aw's when I can, it's not that efest's aren't good batteries just not as good as Aw's
