Issues, Issues, Issues

I have had my eVic for not quite a week and at first I was really loving it, but that has all changed. Prior to the eVic all I had was an eGo Twist. When I first got it I felt like I was getting a better vape than on the eGo Twist, but lately it just isn't a good vape at all. It is randomly powering off, sometimes in the middle of a puff. I have checked and re-checked all of the settings and everything looks like it is good to go. I am running the latest firmware also. Even when I crank it up to 11W it just seems like it has no power. I find that switching back to the eGo Twist gives me a better vape and much more vapor. It does seem better in the morning with a full charge, but currently it isn't hardly vaping at all and the battery is still at 50%. Is there really that much of a voltage drop on it? I should also note that I am using a Kanger ProTank on it and have been since I got it. I have tried some carto tanks and while they seem to be slightly better, it still isn't like it was 6 days ago.

Any help would be greatly appreciated, however I feel like I am ready to go get something else for my dedicated all day vape device.

After I started this thread it occurred to me to try it in pass-thru mode while charging. That made all the difference and was more like it was before. So it does look like there is a significant voltage drop. I was not aware of this in any of the reviews I looked at unless I missed it. Since I did not buy it brand new and purchased from a private party, is it possible that the battery is going bad? If so, is there a way I can check the battery to determine this? It holds a charge really well and after all day of vaping I am rarely below 45%. I am using the Samsung 18650 that came with it.

got mine brand new and never had thsi problem before with any of my batteries including the samsung one.
maybe you can try another battery.
if it has the same problems then maybe there's a problem with your device

fresh off the charger your batt should be 4.2v but i just had one to go bad on me its like 2yrs old an AW IMR 18650 it was 4.0v right off the charger but would only last maybe 2-3hrs i tossed it

How are you charging the battery? Using a external charger, or using the USB cable? I've found that using the USB cable doesn't charge the battery as well as if you were to use an external charger.

Also is this the only battery you have for your eVic? If so then you might want to invest in another battery. Doesn't hurt to have a backup! Myself I have 3 for my eVic that I use in rotation.

yea backups are important.
i have the samsung one, an 18650 AW and 2 18350 AW

 

[rasmith1959]

All three of mine are the Samsung ones. Though I guess when they start crapping out on me I'll get another kind. Probably the Panasonic 3400 mAh kind.

I would suggest verifying if you are using a protected battery or not. Some of your issues sound like what would happen if you are using protected batteries in an eVic, which, like most VV/VW devices with protected circuits, doesn't like 'em..

seems like AW is the best for e cigs

just a heads up, not all 18650 will fit. i have 2 provari batts 2500mah and a frustfire 2400mah that dont fit. i believe the battery length on them Panisonic 2600mah is about 64mm so i would go much bigger. the AW IMR 18650 - 2000 mAh and 1600 mah fit perfect 65mm.

Ok, fresh off the charger I have verified that the battery is at 4.17V. Yes, this is the only battery I have for it. I was holding off on buying more until I determined if I like the eVic or not. I didn't want to get a battery that I may not be able to use in another device. Fresh off the charger it seems to work pretty well, however by about mid afternoon it's feeling really week. Also, something else I have noticed is that every time I put my ProTank on it seems to read the Ohms differently. I can understand a slight variance from time to time, however yesterday it was reading at 2.5 Ohms and today it is reading at 2.0 Ohms. Could it be that my coil is going bad and causing an erroneous reading? And yes, I am charging it through the unit via USB. I currently don't have a charger or additional batteries although will be getting some soon.

Did you check the coil head is screwed in all the way down into the base of your protank? I'm wondering if it is caused by a poor connection...

i have two protanks, when I took it out of its packaging, both coil pack that was preinstalled into the base were not tightened all the way down, check this first, as this may be the cause of poor vaping because the center positive post in the 510 connection may be connecting intermittently...

Yes, I did check this. I have cleaned everything a few times and always made sure it went back together tightly. I did have the same problem you mentioned straight out of the box. I rebuilt the ProTank coil this evening and that has helped a lot. I got rid of the silica wick and used cotton and also made a micro coil. Seems to work much better now, although I still think the eVic feels underpowered.

A few things to note - A failing battery will still read proper voltage. It will not handle LOAD.
Could be as simple as getting a replacement.
I have NOT charged any of my batteries in the eVic since purchase. Always use a decent External charger.

A few things to go over:
Clean all threaded areas - Battery Cap, tube threading, 510 and Ego threading.
Scuff Battery pin under Head with 220 or 400 sandpaper
Slightly stretch Spring to reduce shut off when setting unit down.

Random Power OFF during a Draw, with a nominal Coil(1.8-3.0 ohm) indicates a failing Battery.

Thank you. Looks like I will be going to get a new battery tomorrow. After reading your post, I am really thinking it is a battery issue also. It just does't cape nearly as well as my eGo Twist which has less power. I had just thought when the battery started failing that it wouldn't hold a charge either, but I guess that may not be the case with this one. Also, the fact that it vapes way better while plugged in even with a full charge is another indication to me that it is a battery issue.

THANK YOU crxess!!! I picked up a new battery today and it has made a world of difference. As soon as I dropped the new battery in, I got a huge throat hit and tons of vapor that I never got before. She's a rockin' now!!!

 

[tom_chang79]

Which batt did you get? My next 18650 will be an AW. I currently use their 18350 in the shorty config and they rock!

 

[Greg Brown]

My only option locally was an eFest 18650. I understand they are decent batteries but AW is better. It will work until I can order something else.

 

[tom_chang79]

I got my AW from Provape and Sun Vapers, I believe there are some fakes out there so I get them from these two sources to be sure, since those two online shops are trusted sources...

 

[crxess]

Efest is Decent. I use the 18350's in short mode.(Mini-eVic)

Panasonic CGR18650CH are Excellent. Amazon usually runs a special on 4 around $25.

As for youe Coil readings - eVic is Fast Read. i.e. eVic detects your Tank the instant the center pin makes contact. If you are screwing it on slowly it will usually read a little high.(still loose when read)
You will also see a difference between a warm coil and one that has sat idle for a while.(normal)
For a dead accurate reading, turn eVic off. install tank. Power on.
