Long tiring day, so excuse me for not having more precise info.
A few days of using the "Kicked" leaves some disappointed on the battery life. The 1100 Mah (18500) batteries in "The Boss" won't last more than three or four hours. Not sure of the Vivi Nova's head Ohms, most likely 1.8. Have ran 2.6 ohm also... Anyway, the kick was set less than half its full output. The HIT is totally lovely from the first to the last without deviation.
