I have an aspire nautilus mini that vapes great , today I got my k101 with a smok fuse disk and three efest 18350 (800 mah) batteries.my question is after charging my batteries when I got home I put the battery in and then the disk . Vapes for about 2 1/2 hours and the newly charged batt went to 3.5v sooo was dead right ? Did the smok fuse cause this terribal battery life because well it is 800 mah and my 650 ego lasted for 5 hours on the nautilus . I returned a smok winder 1100mah because it was only lasting for 5 hours ......ridicules I know but with these batts being the imr version , do they need the fuse , could this fuse have drain my batt ? It wasn't like firing on its own or anything as I don't have the tubes cranked down all the way tight causeing a automatic fire like I have read , the button still has a small amount of space when pressed . Any ideas about these Smok fuses ? The vv battery I had from Smok kinda made me have a little suspicion for Smok stuff.
