I've had the imren 26650's for about a week now, and I really like them. While they dont last as long as my old mnke's, they hit better and go lower. [emoji2] I have tri 26g paralell build comin in around .16-.19 and they last around 5-6 hours before I need to recharge. I dont ever go lower than that, but with no heating issues so far, maybe someone who cares for that low of a vape could. Not claiming to be an expert, but these batteries work well enough for me.
