Also if it can fire a 0.15 or .25 coil it should have no problem firing a 1.8 ohm coil at around 8W or so being unregulated.I don't have a smok V8 but reading the specs on it it should work fine with that Nauty Mini since it has a 510 connection. Being unregulated the power it puts out will decrease as the battery voltage drops from 4.2V fully charged to 3.4V discharged. Your battery does have built in protection which is good.
