Not going to get into a whole safety thing, but if your friend's MVP is using a .6 ohm coil, and firing, that means the MVP is malfunctioning, and pulling at least 6 amps (even at 3.7 volts). What could happen? Well the amp limit on the MVP is rated at 3 amps, so it is not likely, but certainly possible that the battery could explode and disfigure your friends face. Just being honest.
If you are thinking about building your own coils, it isn't rocket science, but you have to know your device amp limit, and don't exceed it.
Volts/resistance is amperage. Ohms=resistance Radio Shack= place to get cheap but effective multimeter
