My wife thought she was helping and picked up 2 protected ICR batteries an 18650 and an 18350 yesterday. They are both Panasonic I believe (not labeled, but look vaguely like some pannys I've seen; haven't bothered to look them up yet). Can I somewhat safely use these on my mechs to run maybe a carto tank or something? Or should I relegate these to the junk drawer until such time as I get a flashlight or regulated mod that can use them? I know I should probably not use them with my rebuildables.
