Is my iTaste VV V3.0 "broken"?

[NickWhit1992]

So, I was looking around for the lowest ohms my iTaste is supposed to be able to handle, and I found this thread: http://www.e-cigarette-forum.com/forum/showthread.php?t=559391. According to the information contained therein, the lowest ohms it can handle is 1.2. According to the technical information, 0.8 should be impossible. However, I've been running a 1 ohm dual micro coil for over a week, and a 0.8 micro parallel for the last several hours, both in ProTank II Minis, with no problems. Is something wrong with my device?

Current vape:
Innokin iTaste VV v3
PT2m w/ 0.8 ohm 5 wrap parallel micro coil at 11w
Local juice

Probably not, but it's not a real good way to get long life. It will stress the battery and lead to early failure.

The electronics are probably just a bit out of calibration. It's also possible that what's being reported by the device is off. It should regulate within it's capabilities, and if conditions are created that go beyond those, you may not actually be at 11 watts.

The numbers are also partially for your safety. Over stressing the battery isn't very good for it, as David said.

That said, the specs on batteries are typically what the manufacturer tested it at and has determined will give it the longest functional lifetime.

When I first started vaping, the ego batteries at the time said never to use anything below 2 ohms... I prefer 1.7s, so I used them. Nothing bad ever happened and they're still alive today... 3 years later. I stopped using them regularly a year ago or so, but they still work well.

The advice given in the other thread was for single coils. You are using dual coils. Dual coils are usually parallel and a 1 ohm dual coil is made up of two 2 ohm coils. Although you are vaping at 11 watts, you are really pushing that through two 2 ohm coils - so 5.5 watts per coil. Your iTaste is sending current through 2 x 2 ohm coils. In the example given for a single coil at 1 ohm using 3.7 volts as a guide, it was noted that the amps required (3.7) were beyond the limits of the iTaste battery. With a 1 ohm dual coil the current is divided between each coil.

So you have two 2 ohm coils and your iTaste is set at 11 watts. The watts are split between each coil - 5.5 watts per coil. The amps required for each coil are 1.658. Double that for total amps - 3.316 amps. This is within the maximum current output of 3.5 amps for the Itaste vv3. That's why you are able to run a 1 ohm dual coil on it - although you are pushing near the amp limit and it won't be the best for the battery.

The same calculation for a 0.8 dual coil puts you at 3.708 amps total - you're right, that shouldn't be possible with your iTaste. My question here is how accurate your ohms measurement is. Ohm meters can have margins of error, so that your overall 0.8 may not be an accurate resistance measurement. As David mentioned, there may also be some variation with your device calibration.
