I am having the same problem with a VapeCige VTbox200 which is the white V2 model. It worked great for about 3 weeks, then died in the identical way as Smoove0214's. It will not come on unless plugged into USB, and it reports "Ohms too high" when I fire it (also while plugged in, it does not fire when disconnected). * I have checked the Fuse visually and with an Ohm reader. It looked ok (24ish, which I think is correct). * The Device monitor shows all three cells as good, voltage at 3.83 each, 11.49 overall. Any help would be great.
