Found this thread by searching so thought I would add to it rather than start a new one and see if it gets any attention. I just picked up a used SB and kick. Using freshly charged new AW IMR 18650 2000mah battery and the battery drained from 4.17 off the charger down to 3.03v in about 24 hours time. I only took about 2 dozen puffs on it tops. Obviously I have a drain and I am working on process of elimination here trying to determine if it is the SB or the kick or the battery, already elminated the battery as it drained .3v on a different one in about 5 hours today while just sitting. But has anyone heard of a kick doing this or a SB?
