Are IMR batteries the safest or are IMR hybrid batteries safer? Are either of those batteries sold with protection? (I recently watched an MNKE battery get hit with a heat gun and then get short circuited & all it did was vent a tiny little bit of gas. That seems pretty safe!) I’m looking at possible 26650 batteries which is why I am asking. I’m not exactly sure of all the specifications I need to look for when matching a battery to my device. My device is a Geekvape Aegis which can take 26650/18650 but that’s just the size of the battery right? What about voltage, amps (continuous discharge vs pulse burst)?
