I just received my OBS Engine Nano from China, shorty after reading up on some of the health concerns surrounding firing your coil prior to wicking and filling. Anyway, I didn't check to see if it would fire until it was built. Despite having read the coil packaged with this product would sit at around .35 ohms, I figured I would give it a try on my 30 amp battery and keep the wattage fairly low. It turns out my battery my not be 30 amps but 20, so I began firing at 10 watts, I fired it on a Smy50 Tc after testing the resistance of the coil. Seeing it at .23 watts on this device, I was disappointed and a little nervous to even fire the thing. I had hoped to play around with the coil and wattage for a few days - testing the vapor production - before going out to shop for new coils and a nice battery. So I gave it a few clicks regardless of my concerns, and after managing the calculations...but nothing happened. What I didn't immediately realize was that a). My coil wasn't heating up enough to produce vapor, but it was heating, and b). There was a vast difference between the voltage readings of the battery when switching between my Kanger and the OBS. The Kanger ranged between 3.1 and 3.4, while the OBS reads only 1.1 - 1.3 volts. I have 4.2 volt batteries. I have done a bit of reading on the possible reasons for this problem and I understand that if I'm dealing with a short I could be in dangerous territory. Just to cover these easy points: I know my 510 post is connecting with the Smy. I don't, however, know how securely - even though this model features a spring mechanism to accommodate longer posts. And the coil is very tightly screwed into the posts (this deck makes for a much easier build than that of my Kanger) I could be wrong, but if it's reading .23 ohms and it is, in fact, heating slightly, this isn't necessarily a full-blown short. Maybe an insecure connection? I'm leaning toward this issue being one of a faulty post, but maybe there are some things I could try if anyone has suggestions. There's no way in hell I'm gonna RMA this thing back to China, but I was really excited to test out some different coils and juices after reading the excellent reviews about the vapor quality even at low wattage.
