I have few questions about my new VV box mod

[alamor]

Hello fellow ECF members!!!

I recently purchased a VV box mod from a fellow member here on ECF. It is one of the entry level VV box mods that madvapes.com sells for $34.99 It seems to work pretty well but I have a few questions about it that i'm hoping one of you VV mod guru's can answer.

1) When I use a dual coil 1.5ohm Cartomizer it seems to get very very hot and I get a burnt taste. I have tried dialing down the VV knob but it doesnt' seem to help much. My carto is definately nice and wet so it's not the filler burning(i don't think anyway) but when I use a regular 3ohm carto I get a wonderful taste and great vapor production. Do they NOT recommending using a LR carto with VV?

2) I am still waiting for a battery charger to show up. The member I purchased the VV mod from sold me two AW 14500 batteries with it, and fully charged them before he shipped them to me. How long can a person that is a heavy vaporer count on the batteries lasting for? I should be getting my new charger tomorrow or the next day. Will they last that long?

3) This really isn't a question, If all you VV guru's could give me any tips, tricks or suggestions I would be greatful!! I am looking for anything that would help my transition from my stock Riva to a VV mod be smooth and not be to much "trial and error"

Hi Alamor, I am not a guru, but in very general terms, LR atomizers are popular for fixed voltage devices because they "simulate high-voltage vaping" (according to one blurb I have seen at a vendor's site). This just really means that they are hotter with a fixed voltage device, and give a similar experience. This is at the expense of battery life, it draws more amps and runs it down faster.

Higher resistance atty/cartos are nice on a VV device, because you can crank it up and get a higher temperature, and it draws less amps. LR attys are shorter lived in the first place, so if you crank them up on a VV, they are both easily too hot, and won't last as long.

I am puzzled that you couldn't turn it down enough to be good with LR. I am not familiar with the Madvapes box, but I hear nothing but good things about it for it's intended purpose. I can't answer you on batteries, because I have never used those. The only suggestion I could make would be to stick with 2.5 or 3 ohm atty/cartos, they will also make your batteries go longer between charges. As always, try several and find what works for you.

The 1.5 ohm DC's (actually I think they are usually 1.6????) are two 3.2 ohm coils and should hold up to 5 volts. Are those batteries IMRs?

Anyway, IDK. Sounds like a wicking/wetting issue of some sort. Those with LR DC experience will have to chime in.

Batteries won't last nearly as long with DCs since it's twice the amps. You'll want that charger soon I suspect.

LR DC issue with any vv mod would be amp draw and mosfet. In other words, can it handle the amps? Using that carto on it is like using two of the 3.0 ohm cartos at the same time (since 2 x 3.2 ohm coils).

Attypops,

I am not sure if they are (or what IMR even is lol) But the batteries say the following:

AW 750 mah
they also say "IC" on them. so i'm guessing they are not IMR's they are IC's?

 

[AttyPops]

I think the IMR's say IMR on em. Anway, nm, I asked for completeness..... That's not why they are getting burnt taste. Are you vaping at, say, the middle setting (like 5 ish volts) or lower?

Ya I have it set on the mark that the member I purchased it from made on the dial. He told me that it was set at 4.3 volts. And on my regular 3.0ohm Carto's its very nice...warm vapor, alot of vapor production and the taste is AWESOME. With the DC LR carto's not the same.....very hot, and the taste is bad. Almost like an actual cigarette smoke taste. And i'm using the same juice in both carto's. So, I guess I will use the 3.0ohm carto's until I can maybe get some HV atomizers or carto's. I know it's a huge learning curve, but since I got into vaping, every learning curve has cost me alot of money. So I would like to avoid that this time if possible.

 

[AttyPops]

Yeah, that what's puzzling me tho. You see... the Dual coils are just that... TWO 3.2 ohm coils.... which nets out to 1.6 ohms.

So how can that be burnt (as if the voltage is too hot) when the 3.0 ohm carto works????

That indicates that a coil is not wet, not that the voltage is too high. So you don't/shouldn't need HV stuff. See?

Anyway, for now use the 3.0 ohm carto with great taste and enjoy... batteries will last longer that way too. DC people will have to chime in here....................

EDIT: P.S. Random thought: Are you sure it's a DC????? If it's a regular 1.5 ohm singe coil carto, that could be bad/burnt.........definitely use lowest power on that.

EDIT AGAIN: P.P.S. f-ing cartos

I wish I could add something, but I am learning a lot from this thread. I just got one of those vv mods (directly from MadVapes). I like it, but have not mastered it yet. And I was about to order some dual coil cartos, so I will be interested to hear more posts.

From my experience (pretty heavy vaper), you will need the charger soon. I also have a pair of 14500 batts, and have come to the conclusion that I need a second pair. I kill them pretty quickly.

Good luck with the mod - and keep posting. There are others out here with the same questions!

 

[AttyPops]

FYI - my question, on any mod, with the DC stuff is "can it handle the amps or will it fry the e-cig if I chain-vape?".

So, I use a 5 volt mod and a 3.0 ohm atty. But if I were to use a 1.6 ohm DC instead (and I'd probably have to use IMR batteries since they put out more amps and won't trip protection circuits) and assuming the 14500's would work, I'd need 3.125 amps. I think I built my last mod with a 3.0 amp regulator.

Now, I know it's not on 100% of the time, but I didn't even bother to use a heat sink. Now, if I had a mod, even a vv one, I'd look inside and check what regulator it used and ask around and see what others use on whatever mod. I've heard of people having battery tripping issues, and I think regulator heat tripping issues too.

Just FYI. The standard coil stuff (non-DC, non-TC) doesn't have this issue so much. I suppose you could have it with 1.5 ohm single coil stuff, but it would probably just pop the atty coil and insta-solve the problem for ya.

Thanks AttyPops. Since I have the same mod as the OP, I may hold off on trying the DC cartos until I get better educated on some of the electrical issues. I don't quite follow what you are saying, but I'm sure there are resources on this forum to fill in the gaps. In any case, I'm going to X those DC's out of the shopping cart that I was about to complete.

Alamor: thanks for starting this thread. I hope others post, as I'm learning a lot.

 

[AttyPops]

Dude, I'd try em... or at least one of em. But check it out. Some don't like the duals, some love em. IDK about that specific mod. I'm not trying to talk you out of trying them, I'm just discussing DC's in general and mods in general, since it's an interesting discussion.

Still sounds like a wicking issue on the DC to me. Or it's a single coil 1.5 ohm.

 

[dupont]

I'm not taking it the wrong way - you're right, I'll probably pick up a single (not the 5-pack I had in the cart). But to be honest, although I like this mod, I still like my simple "super mini" batts. That's not to say I don't want to experiment, etc. But probably good to go slow.

Someone slapped me down in a post earlier today for not educating myself more, so I'm just being humble...

 

[AttyPops]

Sapped down? Slap back! lol. Unless they say "NO! don't use xxxx chargers on yyyyy batteries" or something. Cuz then, they're helping keep you safe!

On Topic- Still waiting to hear from experienced DC users on the burning DC............

 

[dupont]

Hey just as a by the way - I believe you told me not to use xxx charger on a yyy batt. That was great advice - no slap down. Thanks! I was referring to someone who told me I could find an answer in one of the stickies - which is true I'm sure, and I do read them. But another poster gave me the answer I was looking for (about batt size). I live a few blocks from the Library of Congress, but I still ask folks for advice sometimes....

Back to the topic at hand.

I have the MadVapes VV box and love it. Simple, affordable, and effective. A couple things I'll mention...

VV drains batteries. That's a fact of life with any VV device. 14500's are cheap so an extra pair or two will greatly enhance your experience. I personally get about 4 hours of hard vaping out of one pair.

Also, MadVapes has their own sub-forum on ECF. You might consider posting your questions there, where you'll find a nice group of helpful folks...

I get about 5 hrs max of heavy use on my vv mod from madvapes.... as to the lr cartos, I use them on a 3.7 mod only, and typically use higher ohm cartos on my vv mods...

 

[AttyPops]

FYI - here's another interesting thread that, in part, discusses burning carto issues........

http://www.e-cigarette-forum.com/forum/new-members-forum/211114-burning-cartomizers-sigh.html

I still think it sounds more like a wicking issue than a voltage issue..........
