I've seen an eVic post about Issues. I’m glad I’m not the only one with problems – I somehow knew I wouldn’t be. My distributor told me I was his only person with Issues.

I purchased a full eVic box with Firmware v1.1, and a spare joyetech 2600 mAh battery. I installed the battery that came in the box, and it worked great. I used it for a little while, and then put the battery on charge. It charged fine to a full Successful Charge, but it took 5 hours from 43% - the Manual says it will charge the battery is 3 hours – WRONG! I knew it wouldn’t charge that fast, but that’s really OK, because it is being charged at the proper rate.

I used the eVic without issues until I decided to install the Spare battery and charge it. That battery charged up to 97%, and then the displayed charge dropped to 94%, and just kept varying between 94% and 97%, and never reached a Full Charge. Knowing the other battery only took 5 hours for a similar charge, after 8 hours, I unplugged the charger at a 94% cycle and used that battery in the eVic. The eVic showed the charge to be 99% (odd!). It worked good, but when I recharged it again, it did the same thing.

So I decided to put the first battery back in and use it a while, so I could and charge it, to see what would happen. This battery did the same as the Spare this time. Only it got Worse. The battery got to 97%, then dropped to 94%, and did that a couple of times, then dropped to 93% after a while, and then 30 minutes later, after not changing from 93%, it dropped to 92%.

I watched it at 92% for a while, then took it off charge and used it. The eVic worked OK, and showed a 98% charge (even more odd!), but this really concerned me, knowing how dangerous Lithium Ion batteries can be. I’m having to return this set for a refund, as the only resolution offered.

I have had nothing but issues with each and every e-cig I’ve tried since I started this whole Experiment 3 months ago, so I was not surprised at all when I had a problem with another Chinese product. I thought I had made a good decision in selecting a “real” product, made by joyetech, in their Top-of-the-Line eVic, over some of the knock-off, no-name products I’ve been introduced to by a local distributor in the eGo-T design, and others, leading up to this eVic purchase, but maybe ALL Chinese products are Inferior. It’s certainly starting to look that way.

I selected the eVic because it had the battery size and features of the American Mods, plus some features in Firmware v1.1 that aren’t always easily found, but I really don’t know what to think any more. Now I have to find a really good e-cig, and a vendor, again.

Has anyone been able to find an e-cig with an 18650 Battery that does not have Issues? I’d like to have Variable Voltage, and Variable Wattage if possible, with a versatile 510 Connection for Tanks and Clearomizers, and a good Control Head that doesn’t rely only on the protection of a Protected Lithium Ion battery. It would be nice if it was pre-qualified for a Lithium Manganese Battery, too. I’ve read that the Provari has this LiMn pre-qual, but I have no idea about its quality.

The eVic had all of the features I was looking for (minus the LiMn pre-qual), plus some things I didn’t really care about, like MVP, and at $105, it seemed like a really good deal. It was pretty easy to use, and change the settings, and I loved the big screen, with all the details it displays, but I need something without Issues.

Maybe it was my Spare Battery that created problems, and apparently ruined the Control Head. Maybe I’ll ultimately give the eVic another try, from another vendor, but I’d appreciate the input from any Happy Users.

I’d really like to hear any and all Success Stories.

Thanks,

Hi LongHaul,

I haven't looked into the ProVari yet, but I'm going to have to do that now.

If there are different models, would you please tellme which one you have?

Thank you very much,

100%VG


You have to pay 20 bucks extra for the extension cap for an 18650 but its well worth it. Like I mentioned in another thread, I only own 2 PV's. 1 for my main and one as backup, with a Provari I dont need anything else.

Hi wyojoe,

I saw the eGo-T Mod 18650 2200mAh Device before selecting the eVic, and thought very hard about it. I could get 2 of them for the price they are asking, and be able to charge one while using the other. I may still go that route, and I'm glad that you are enjoying it.

I'm glad to get a good recommendation on the eGo-T Mod 18650 2200mAh Device, and will consider it.

Thank you very much,

I haven't had any trouble with my eVic, my Provari, my Vamo, or any other 18650 mod. From your post, I'm really not seeing that you have, either. It sounds to me like you've got some flaky batteries.

Hi IMTrick,

It's hard to know if it's the Batteries, or if the 2nd Battery damaged the Control Head, since both are doing the same thing now. It seems to have gotten worse, which makes me think it may be the Control Head. But the Distributor wants it back and refund my money, rather than send parts or replace the whole thing, so I'll honor his wishes and find another Vendor. I figured it was really only a small percentage of people who'd have a problem with the eVic, or really any e-cig, but I seem to be the guy who's going to get the Bad one from any Batch.

I'm glad the your eVic is working well for you, and really wouldn't mind having another one.

Thanks,

Sorry about your bad luck... and who knows? Maybe it is the head. I'm not genius when it comes to electronics. If it spits out vapor when I hit the button, I'm happy.

One word friend......ProVari

American made

Without issues, indeed the Provari, but it does not have a vw option, and as we speak, that's the way I vape today. No longer worried about what atty/carto ohm, just screw and vape.

If you're looking for a mod that's no frills, solid, and offers vv/vw at a much more affortable price, the Vamo or Zmax Sigelei is one path to take.

I have all three mods mentioned (Pro/Zmax/Vamo), and all have +/-, but that eVic is my favorite because of the potential that it offers every firmware upgrade. Now, if I'm doing outdoor activities this winter, well, my trusted REO is the way to go....it could survive a nuclear winter.

BTW...rule of thumb I've followed for 3yrs, when buying a new mod, buy new/correct batteries that the manufacturer recommends.;)

Hello VIPOD,

According to my present understanding, my Distributor has agreed to replace my eVic and handle it as a Warranty. I sent it back on Thursday and I am awaiting a replacement. So for now, I'm going to stay with my eVic. If I don't actually get a replacement, I will seriously consider something else. The fact that the Provari does not have VW does not kill it as an option, but VW would be nice to have. Considering the way the Market is going, the Provari will likely come with VW soon.

I've done a good bit of research into the Provari since I posted the question, based on recommendations made here, and have found it to be highly desirable. At twice the price of the eVic, having been only aware of the Provari by price and not reputation before this post, I decided to try the Joyetech eVic, because of budget considerations.

I have not seen a slew of posts about problems with the eVic, or even negative design comments - at least not in the newer Firmware 1.1 models. I have only seen one post on ECF, with only one or two additional people also with a problem responding to that post. So this is somewhat encouraging in favor of the eVic. If there had to be a bad eVic out of 100 from my Distributor, someone had to get it, and that was me.

People have suggested devices like Precise models (Beautiful!!!) and Reo Grande models (didn't look them up yet), and the Vamo. The Joyetech eGo-T Mod Battery is neither VV or VW. The Precise models have a Bottom Button. I like the upper-level side button design, and the Precise models are too pricey for me. They have an excellent design, smooth operation, are American Made, and are stunningly beautiful, but I can't afford one right now. The Vamo is great on VW, and they seem to have the bugs worked out in V2, but I don't find it particularly attractive.

You, VIPOD, also mentioned the Zmax Sigelei, so I'll do some research on that, and the Reo Grande.

I couldn't agree more about only using recommended Batteries. I did an extensive amount of research over the Unprotected Lithium Ion Battery that's used in the eVic, before I made my purchase. First, you cannot currently get anything higher than 2250 mAh in a Lithium Manganese Battery, and the best one is the Panasonic CGR18650C IMR at 2250 mAh. Secondly, a Lithium Manganese Battery can safely output up to 10 Amps. A Lithium Ion Battery can only "Safely" output 2X its mAh Rating. This is why the eVic asks you about the Battery that is installed - so it can safely limit the Maximum output current allowed at 2X. While I believe that the eVic could safely use a Lithium Manganese Battery, via this same Current Limiting Protocol, the fact is that, if the eVic Control Program should develop a problem, 10 Amps of current could easily do more damage than 5.2 Amps.

I don't know how valid this thought actually is, but the fact remains that Joyetech designed the eVic around a 2200 and a 2600 mAh Unprotected Lithium Ion Battery. Joyetech has NOT authorized the use of ANY Lithium Manganese Batteries to date. And considering the whole Battery Safety concept, it makes no sense to purchase any Battery at all other than the Samsung ICR18650-26FU Battery that has been approved and ships with it, with the exception of the original 2200 mAh approved battery. This way, there's no problem with Form, Fit, or Function. End of Story. This 2600 mAh Battery is properly charged, according to the Samsung Spec, at 520 mA, for the best possible Battery Life. The eVic charges it at 500 mA.

And you (the public) have to know that there are batteries, and there are BATTERIES. There are good reasons to stay with high quality brands, and pay a little more for a good battery. Any Battery that claims to have a higher mAh Rating than any know Panasonic design, is most likely not labeled correctly. This false labeling will be justified by improperly conducted Testing, often using very low discharge rates. You should always look up a Battery that you are considering on a site that will show you graphs of Charge rates, Discharge rates, and Capacity, and give comments and recommendations about how well it performs and holds to its labeled mAh Rating. Even if you cannot understand the Charts and Graphs, the Summary Comments will tell you what you need to know.

Not every Battery meets the 18650 Specs, especially for things like Width and Length. The 18650 Spec says that the Battery is 18mm wide, and 65mm long. The Protection Circuit of a Lithium Ion will add .3-.4mm. A Button Top (+) Terminal adds .2-.3mm. Having both can add up to .7mm, and some Protected Lithium Ion Batteries are 18.9mm long. This is partly why VIPOD made this comment, because he knows the Vamo only works with Specific Batteries of a particular length and width, and a particular End Cap design. Some Batteries are actually too Short for the Vamo, because of the (-) Spring.

And not every Battery Charger meets the 18650 Specs for properly Charging a Battery. It's best to get . . .
1. Pila IBC (Best for any Li-Ion over 600 mAh) - Charges 2 Batteries at 600 mA - Terminates at 4.17 Volts
2. Xtar SP2 (Best for LiMn) - Charges 2 Batteries at .5, 1, or 2 Amps - Terminates at 4.23 Volts - high but acceptable
or
3. Efest BIO (Good) - Charges 2 Batteries at .5 or 1 Amp - Termination Voltage not stated in the review I saw.

The 500 mA Charge rate is good for any Li-Ion over 600 mAh, but best if used on 1000 mAH Battereis or greater. The 1 or 2 Amp Charge Rates should be reserved for LiMn, with a Lithium Ion never being Charged at more than ½ its mAh Rating. Therefore, it is acceptable to charge a 2600 mAh Battery at 1 Amp, but not at 2 Amps, and the best Battery Life will be obtained by charging it at 500 mA, or the 600 mA Rate of the Pila.

Again, look up the Charger you are considering, and even if you don't understand the Graphs and Charts, the Summary Comments will tell you if it can safely be used because it properly charges a Battery. Every bit that a Charger is away from the Spec, means less Battery Life. Getting too far off Spec can cause Battery Eruptions, Fires and even Explosions.

Thanks VIPOD, for bringing it up. If this Battery and Charger informations isn't already listed in something like a Battery Forum, I'll repost this info there.

You people have all been very helpful, and I really appreciate your time, but for now, because this replacement has been offered, I'm sticking with the eVic. My Distributor has proved to be a Trooper, and I'm really happy that mine is being replaced under Warranty - the whole eVic Kit Box, and the Spare Battery. So every questionable item is being replaced, and I get to start over fresh. I couldn't ask for more.

Thanks again to everyone,

100%VG
