I need to hear it from the experts, Is it safe for a dual coil atty rated at 1.5ohms to be at 5volts? I have been having doubts about this but i see it in reviews all the time. I tried it but busted my atty probably i am doing something wrong not actually busted but it read 3.2 ohms after i tried it at 5 volts which was 1.5 before. Although 5/3 is at 1.66 and should be within the 1.5 to 2 acceptable range. Any comment will be greatly appreciated as i like the heat that the 5 volts produces.

Yes i used this on a provari v2. I have been an ego user before switched to vv to give it a try i like it very much and would like to use it to its full potential. So far i am in the process of testing, learning based on videos, reviews and ecf. I have not come across lr dual coil cartos having issues with my pv yet and i don't know if this is the case. But this is interesting, i'll try to dig more on that matter. Thanks.

You burnt one of your coils in the carto. A 1.5ohm dual coil is made of two 3ohm coils. When you use a dual coil, you draw the amperage of the whole carto, not of a single coil. so 5V/1.5ohms = 3.33Amps. That's the problem with using them on some VV, like the LT, which has a 2.5A cutoff. The LT will automatically adjust your voltage down to 3.7V if you try to vape a 1.5ohm carto. When the Provari exceeds it's cutoff, it will stop working and display an error code. It sounds like instead of popping the whole thing, you just burned out one coil, so the Provari thinks it's a 3ohm carto now and still lets you vape it.

It's safe to vape a 1.5ohm atty or carto on 5V. But it doesn't bode well for the carto. That's almost 17 watts anyway. Do you like vaping that hot? Try 2ohms at 6V. That's 18 watts at only 3A.

Thank for clearing that up sailorman, best explanation to my doubts. What im only after is mimicking how hot an analog is. Currently my setting is @4v and seems carto is still fine. Ill try 2ohms at 6v.

I think you'll find that you'll never be able to mimic the 1200 degrees of an analog. All you'll end up doing is producing harsh, tasteless vapor as you burn up carto coils. What you're probably looking for is "throat hit". That's produced by the nicotine. Some juice adds other ingredients to help it. A high PG, high nicotine, low VG juice will have more throat hit. If you use 6V with a 2ohm carto, you might get away with it, but be prepared for short carto life. 3amps and 18 watts is really overkill. With the right juice, you should be able to vape at around 12 watts. Try a 2.5 or 3ohm carto on 6 volts first. But make sure you have some decent high nic, low VG juice.

    A 1.5ohm DCC has two 3ohm coils in it in parallel. When both coils are intact it would read 1.5ohm, if one coil is burned out it would then only be reading the remaining 3ohm coil.
    3ohm coils, even if there are two of them, perform best in the 4.5-5v range. 2ohm coils perform best in the 3.4 -4.2 range.
    When you go above those ranges chances are that the juice you are using will take on the burnt or dirty sweat sock taste.
    If you really want to vape at 6v get some 2.5ohm DCC's (5ohm coils), but understand that your nic intake will double what it says on the bottle. (a 24mg juice will be like using a 48mg juice), so be careful with that.

    Having a V2 means that you just got your Provari, and yes it's a lot of fun seeing what it can do. But, lets face it, a lot of what it can do simply is not practical.
