OK this is my second DNA 200 device, my first is a VT 200. Yesterday I ended up purchasing a Reuleaux DNA 200, because I needed better battery life to make it through my shifts at work without having to either carry a second mod, or leaving my VT 200 at home and bringing my Sigelei 150 TC to work. Anyway as I was leaving work, and talking to a coworker outside I went to hit my mod, and nothing. The batteries still had more than 50% charge (set it up in escribe for 33.3wh, using LG HG2's). So I went home and connected to escribe, hoping it was being a tad glitchy and as soon as I plugged it into my PC the Wismec logo appeared, but the atty resistance was showing 0.00ohms. I removed my atty, put it on my ohm reader which indicated the resistance was in fact .25, so I tried a couple other attys and the results were the same. I removed my batteries and verified that they had a charge, all three showed 3.8v. Looking through other threads all I can assume is that the fuse popped. My question is why would the fuse pop with relatively conservative settings? I vape at 80w/.25ish ohms. Other steps I took include checking the resistance in escribe, which indicated "?". I verified the firmware (runnin 8-21), and went into debug mode to verify it wasn't a screen issue (7 clicks on the evolv logo inside the help menu, screen said 0). Any help would be great. I literally have had it less than 48 hours, but because it was the second to last at my local B&M I am not holding my breath with regards to being able to exchange it. Thanks.
