Could be a multitude of reasons why it exploded . Electricity does some crazy shit , but will never act like that unless something was wrong . A mech mod all mods actually are just battery shorts . They complete the circuit , and current runs through the coil . Something that could ' ve gone wrong would be a bad battery does the note 7 come to mind ? Also , a bad set of coils could cause problems . Regulated mods have short protection , mech mods don ' t . I ' m sure you know all of this . The problem is incompetent people using mech mods . People who don ' t know shit about electricity . They ' ll use batteries with low discharge rates , or build coils with a resistance that causes some crazy shit to happen . It ' s not the mods , it ' s fools playing a game with electricity that they don ' t understand can be dangerous .
