A few observations. First battery fires are possible, but almost all of them occur from charging, usually from overcharging, or from being physically damaged. If you buy a pack that’s made from Li-po’s be sure they are either 186500’s or 21700’s. The last zero digit indicates they are metal encased cylinders, the first four digits indicate physical size as in mm’s, a 2170 is 21mm and 70mm tall for example. The metal encased cells are much harder to damage, usually takes serious hit to damag
