Yes, sorry for not stressing this enough: extra care must be taken when dealing with Lithium cells. They pack a lot of power in a small space, and can be extremely dangerous if mistreated; even physical damage with no heat involved can turn them into fireworks, so always treat them the right way. Never ever short them or apply excessive charge or discharge, use only good quality chargers and never ever let them unsupervised during charge. If a cell catches fire accidentally, don't attempt to extinguish it with water or sand as they are 100% ineffective, keep a specific safety container for Lithium cells at hand and if you feel you can can fit the cell into it to contain the fire in a bunch of seconds hold your breath and do it, otherwise get the f out of there because the fumes are extremely toxic and would seriously harm you before even getting a burn.
