I have used it to isolate/protect both single 18650 cells and pairs. I've also used it to seal circuit boards to hold wires and relieve stress - once shrunk you can "play" with the heat gun in places that are still crumpled or need a little softening/reshaping. Since it is transparent, all covered LEDs are still lit.
