w00t got my Revision4's today, haven't tried one yet (need to soak them first, they have a rubbery smell). However I tested my Revision3 3.7v (3.2ohm) carto's using my new 3.3v batteries from e-liquids.cn

V4L 3.7v KR808D-1 Battery:
* When fully charged, the juice burns easily
* When half charged, the flavor of the juice tastes "overcooked"
* Not sure yet but I think the high voltage/current causes the coil to accumulate crud too easily
* The vapor is quite hot

e-liquids 3.3v KR808D-1 Battery:
* The flavor is spot on even when fully charged
* Airflow is brilliant so far, pretty much perfect with the CE2's
* They require maybe 1 second more to vape, but its worth it considering the increased flavor
* Vapor is warm

I have a RS 808 batt too, the kind w/ the 'led' at the thread end, but it's a 3.7 batt requested by a vendor to try. He then sent it to me.

It's a cool batt but isn't sealed like regular KR manuals. I hear you on the KR voltage though, they do run hot.

BTW, I notice the cartos in the blister pack have that smell but not singly wrapped. I had the same issue w/ regular cartos in that department.

Seems most everyone is having really good luck with the samples you sent out bad. Wonder why the hell mine are all coming out burnt tasting, even with the Nhaler liquid you sent? I'm apparently just having bad luck. I pulled some atties out of a starter kit I had left over and filled one with some of my liquid and it tasted good and clean, but the vapor just isn't there. I'm spoiled on the E-2 vapor production, but I can't get any of them taste right on my eGo.

Hey all!

I posted this on another R4 thread but I think this is the correct thread. To put it lightly I'm having some difficulty keeping up with the threads! Anyways I just got my R4 from Clouds of Vapor and I'm having some difficulty in using it with my Joye 510...

I noticed that the waffle and cinnamin bun type flavors taste horrible. They lack flavor and have a burnt taste. However the fruits taste amazing! I've also noticed even on the 510 I have wicking issues but its only happened on 2 of the 5 cartos... Lastly, I have noticed that the first 30-40 puffs when i fill them up taste like primer/.... When I dry burn it taste a little better but I thought we didn't have to dry burn these? I wouldn't care but I often forget o_O

help?

Well the ones from COV are +_ 2.5ohms. That ohm level works for some people but not many. The 510 is a 3.3/3.1v device so in theory you should be fine, but a better ohm level would be closer to 3ohms. Shorter drags and not chain vaping can help at the 2.5ohm level. If you are a the 'tinkering' type you could use the PTB mod too.

I think you mentioned something important though; the fruit flavors taste amazing and the other burnt. The juice type also factors in the equation.

As for primer/bad taste; I haven't run across that yet in r4 although some have. Cleaning/dry burn should help. Many people are finding distilled white vinegar to be a good cleaning agent. I'm going to try that but use Vodka now. It works well and evaporates quickly.

So is it the ohms that is creating the bad taste for the certain flavors? I dont have the issue with ANY other carto I've used. Also, where can I get higher ohmed R4?

At least w/ your cinni bun flavor perhaps. Like you said, the fruit flavors are wicking well. It sounds more like a juice issue but others have complained of a burnt taste at 2.5ohms. COV is suppose to get a shipment in this week of the 3ohms.

Maybe you could use the 2.5's you have for the fruit flavors and get some 3ohms for the other flavor.

I think the design of the coil and wick and the fact these coils are robust and fire well, it seems that 2.5 is just to much and can distort some juice, your over cooking them, this is partially the ohm being to low, plus the type of juice combined with the volts your vaping at plus the amount of loops the coil goes around the wick, some have 3 loops some have 4 others have 5 and some 6.

The higher ohm e2 like 2.8,2.9,3.0 and 3.1 ohm run cooler and work on 3.7v devices and lower volt devices. The 3.0 and 3.1 ohm can go above 3.7 volts but ny how much should be tested yourself.,The higher ohm r4 still give that warm vape and shouldnt over cook your juice causing that bad taste.

WHEN YOU GET YOUR PROPER OHM E2R4.

1. Dry burn it for 10 seconds regardless that it doesnt have primer.

2. If you can, loosen the wick with a tooth pic or needle, remove the inner cap if you can and fluff the wick, the wick can be pressed int the slit in a way that prevents juice from flowing through properly. Not on many but I have come across this.

3. If you received the r4 from a local vendor, ask them what ohm it is, if they say 2.4 to 2.6 then i would suggest not using it on a 3.7 device and try it on a lower voltage device or variable device.

it too bad they don't label each box/blisterpak with what's inside. that would make life MUCH easier. I just need to find some r4's of 3 ohm or better in the 808 designation. then I'd be happy. I've been using filler carts for over a year, and I'm looking for something better. don't tell me to drip, if ya do, I'll tell you to shaddup. :)

Where can I get a E2 R4 thats around 3.0 ohm?

Also, if I'm using a 510 which i believe runs around 3.0 or 3.1, shouldn't the low ohm react in a similar fashion to a 3.7 volt battery with a 3.1 ohm carto? I cant figure out why certain flavors taste so bad. I dont think it has anything to do with wicking.

All I can say is that on an eGo battery, I found 3.0-3.2 ohms a very nice vapor. 2.6-2.8 ohms is a bit hot.

I tried both on my 5V mod and they were too hot. They really dont need much voltage to produce the vapor.

My saber touch should be here tomorrow and I have no new cartos :( Waiting on someone here to hook me up if his order comes in proper. After that I'm gonna order a batch of 100 510 at 3+ ohm.

A couple of friends of mine use 510 mega batts and ego, is 3+ gonna be good for them or do the need the lower ohm cartos with them. My only answer to them is to wait till I get mine and try the 3+ ohm and see what they think.

They don't want to wait... Sigh. I think the guy with mega 510 is getting the 2.6-2.8 Is this a bad Idea? Should he also get the 3-3.2 ohm?

I got some 510 XLs from cov last week - probably the same batch you got. I'm using them on eGo batteries and had the same experience as you. Using 50/50 PG/VG juices, the fruit flavor worked ok, vanilla tasted burnt. They are not wicking fast enough. Look at the pictures badkolo posted on the tips and tricks thread. The burner is at the top and wicks up from the reservoir. I started to PTB mod one that I had finshed up and it wasn't going well. So it turned into an autopsy to see wtf I had. By all accounts it seems to be an R4, although it had a postage stamp sized piece of fill inside the well with the wick. All the ones I had out of the wrapper measured 2.4 - 2.5Ω.

So after all that, I opened up a new one, grabbed a fresh PTB, and pulled the caps off. Cut the wicks, tucked them back in, and put the PTB pieces in. Filled back up with the same fruit flavor 50/50 juice and tried it out. It's better. Not like a drip tip better, but not drying out and tasting off after a halfway decent hit.

Good enough that I won't throw the rest away, but probably do the PTB mod on a couple and use them around the house and see how they hold up. Might even fill some with 100% PG juice as a trial even though I really don't care for it.
