iTaste VTR and low\sub-ohm vaping question

[SharkByte]

First post, so I thought I would throw this question out there to the more experienced vapers. And no, it's not the "can a VTR really fire a sub-ohm coil like pbusardo and others say they can?" question. I already know the answer to that by research and watching videos.

First of all, here's my current setup...I'm using a VTR and a Trident RDA with dual coils running in the .9 - 1.1 Ohm range, made from 30 gauge A-1 Kanthal (because it was given to me. thinking about trying 28 gauge.), organic cotton wicks, and typically around 13 watts. This puts me around 3.4 volts and 3.8 amps. I typically run this setup while I'm at work or sitting at home on the laptop or watching TV. I use Kanger AeroTanks while I'm driving or out and about and don't or can't drip. I use the standard AW IMR 18650 2000 mAh batteries. I'm planning on getting a mech at some point, once I decide on what I want, and dedicate the use of the Trident to that mod. Then I can try my hand at some real clouds.

Now for my question ...will running my VTR in this low\sub-ohm configuration on a regular basis like I do harm the VTR or the batteries in any way? I'm not looking to go lower than .8 on the resistance with this thing and according to my calculations, even if I go to 14 watts on .9, I'm around 3.55 volts and 3.94 amps. I may be answering my own question just by knowing the Ohm's law figures on this, but, knowing the numbers doesn't always correlate to the real world.

Thanks for hanging in there with all this, but I figured it would save a few questions if you had enough info.

I think the issue is that that setup will attempt to draw more current than the VTR allows. The question then becomes, will that attempt hurt the VTR or will the VTR just permit the setup to draw the max rated current with no harm, but perhaps a suboptimal experience.

And I dont know the answer. I occasionally roll a low 1.x coil for my Kayfun and go ahead and use it on an MVP at lowest voltage (3.3)/wattage(6.0) and it vapes nicely. That's right at the purported lower limit for the MVP.

I have the VTR and vape it at .8 ohms have been doing so for a couple months no ill effects your mileage may very. The IMR battery will hold up well enough at that wattage I always recommend getting a Sony VTC 4 or 5 Its just the best battery IMO and you wont ever stress it with the gear available at present. I think vaping up to 20watts for the most part can be done safely on a high drain IMR. I have a couple 35A IMR's and they have held up well vaping at .19 ohms on a mech mod

Actually, I'm sure that the current setup I have isn't near the amp\voltage\wattage limit that the VTR can handle, so I think I'm safe there. I'm also pretty sure that using a high amp output battery doesn't really gain you anything in a regulated mod. But I do appreciate the input.

I just want to make sure that using the VTR in this configuration, for a little while anyway, is not going to stress the mod or the batteries too much while I decide on a mech.

Once I tried the Trident on this thing, the flavor and vapor were so much better than my AeroTanks, at least for the juices I can stand to drip with. Some are just too strong to use on the Trident, which is why I dedicate those to the AeroTanks. Once I decide on a mech, the Trident will be dedicated to that and I'll go back to using just the AeroTanks on the VTR. Not real fond of the iClear 30s that came with it. Draw is way too tight, but the flavor is pretty good. Thought about drilling the drip tip out some to see if that would help, but I digress. No need in chasing more rabbits in this post.

your rite there is no gain in using a higher rated battery not a single bit, but its a safety factor in using a higher rated battery we all strive for. You have to understand these lithium batteries can hurt and yes even KILL you, burn your house down and maybe your neighbors house to. Safety should always be paramount in anything we do. The VTR has great protection, but its not fail proof if it for some reason fails to see a shorted atomizer you have a problem that will cause that battery to destroy its self.

I totally agree with you on the safety factor. I'm just trying to hold out a little longer until I decide on a mech. Hopefully I'm not pushing my luck. Just have to weigh the safety factor against the wife factor. Afraid if I purchase any more vaping toys right now, the battery thing's going to be the least of my worries.

LOL I feel you brother I used to get home before my wife now she beats me home so no way to get the mail first anymore. I have stuff shipped to my work that I buy sometimes. For the most part she is willing to let me get what I need she just thinks I now have enough lol

Won't hurt the VTR any. It is however, limited to 5 amps I believe, which means it's unlikely to harm the battery either.

 

[Brian Roche]

VTR allows 3 amps

 

[SharkByte]

Sorry Brian. Pretty sure it's got a 5 amp limit. Plenty of info out there about that, as well as reviews. That was one of the deciding factors for me purchasing this device.

 

[Brian Roche]

Then I apologize, I was told ten times over it was 3. Normally not one to confidently post misinformation.

 

[seanism]

Just look up the limit. I believe it's .7 but some people have gone lower. Not recommended as it will stress the chip.

Buy a mech mod...problem solved...

sounds like everything is within the vtr's limits.

the only one little thing is that the vtr output is probably 6 volts peak pwm, while the figures you're using are the rms or dc equivalent.

6 volts at 1 ohm wants 6 amps, so I guess you wouldn't be getting the power based on the calculations.
