Ohms wrong

[bk78]

So I bought a few vivi heads a month or so ago that we're supposed to be 2.4ohm but I finally got around to firing up the vivi and threw it on the provari and they meter out at 3.6ohms anybody know why there's such a difference? Cheap Chinese knock off? I can't use these they are too high for me I like the 2-2.4 ohm range

The omhs are marked incorrectly ? I've never heard of that with Vivi heads. It's probably either a knock off, though usually you can tell by the build quality or it could just be a screw up on the assembly line, these are all pumped out in Chinese factories by the thousands.

You could try swapping on the classifieds, though shipping isn't really worthwhile .. or try re-coiling them; A PBusardo Tutorial - Vivi Nova Cleaning & Rebuilding - YouTube ? Either way contact the vendor, even after months they might do something for you, though there's a reason why things don't come with any warranty.

The laser etching says 2.4ohms then I test on provari and they are 3.5ohms. Maybe I'll try to recoil them I have wick and wire. Or just toss them. Out of 2 I tested both measured 3.5ohms and I have 2 left not tested yet. The 2.8ohm was bang on the money also with the 1.8ohm. But I ordered 4 extra 2.4 heads with my order because that's what I vape at.

I'd double check with a multimeter. Make sure the connections are clean as well.

Did you subtract the resistance of the meter leads? These can be in the range of 1 ohm by themselves. It's always tricky measuring such low resistance values unless you're aware that this error can be significant.

All I have is my provari. I tried hitting them at 4volts and really nothing then went up to 5volts and its better just too warm for me. I'll just recoil them. Thanks for the help.

Cheers

I've gotten Vision Vivi Novas 2.0 heads reading at 2.4-2.6. My current cheap knockoffs are reading what they're labelled.

Send them my way, the vmax can handle it. Where did you buy them?...interested.

I had a 2.4 that read 3.2.....it is going to happen as these are massed produced and the QC is not always the best, I would just recoil it to your specs, it is easy enough. And they are all cheap and chinese
