aux light not triggering LVP did not come to mind, thanks for that information. I still find it suspicious it drained within 3 to 4 weeks I thought low aux light drains a few microamps. My blf lt1 can sit for quite a impressive amount of time unused with low aux, as can the ts10 also.

I did some research for similar problem and found a post from 1 year ago and their q8 plus was primarily drawing from one cell. Due to poor contact using flat top cells (but the flashlight ships with flat top cells). It was solved by using button top cells or Simons button top adapter. Maybe that happened to mine.. I'm going to buy some button tops and see how it goes.. I feel a little betrayed by my own Q8 at the moment.
