A few points.
First, you need thin wire. About .30mm Titanium Grade 1. The Proteus won't work with much thicker than that. You also need to be an expert coil winder. These are tight very coils with multiple 2mm wraps.
Second, on the orange lights. The guide (which I edited) is misleading at beat and wrong at worse. A three second orange light does not (at least always) mean a bad battery. If you time Imeo's orange lights in his demo video, they're three seconds, and he's doing just fine. (I incorrectly reported above that my batteries were bad on the basis of the three second orange light the Proteus shows when you fire it up.) Once the Proteus detects your configuration, it displays an orange light for three seconds (not two, as the guide incorrectly states). While the guide reads that your battery is bad if you get a three second orange light, this is not true. Your battery almost surely isn't bad when you get a three second orange light upon detection.
Third, no 14500 IMR battery I have found (even from reputable sellers like RTD who apparently sell genuine AW batteries) are performing as they should. I have a new battery tester and charger. These batteries are not up to snuff. The batteries have an internal resistance which is far too high, for one. And they don't check out at the reported mAh. They seem to run low by about 50-75 mAh.
Finally, you aren't going to get good
vaping life out of the Proteus. With fairly mild
vaping, expect to change batteries at least three times per day. If you vape heavily? Well, the device seems to work flawlessly for home vaping if you have plenty of batteries on hand. Taking it out? Nope. Not unless you want to keep a good half dozen (or more) batteries on your person. (The Penny v4 mini tank is also too small for my taste, but of course, you can use other tanks.)
For me, this device doesn't work. It requires far too much battery management and that's the deal breaker. For my wife, it works like a dream as long as she is at home with multiple batteries in constant circulation. I would never take this device out. It's strictly for at-home vaping while you have tons of batteries in a constant charging cycle. It fills that niche flawlessly (once you've figured out how to work the kinks out), but that's a very niche niche.
