Should have taken a picture of my 3S 5500 with one layer peeled back at a 45 degree bend. One heck of a lawn digging hole. Bent it back to flat, whacked it with a rubber mallet, expected Armageddon, but it refused by staying a regular lipo battery. Not even reduced capacity. Not sure what to think after thinking long and hard about it.
Dont recommend this at home ( see line number 2 in the after commemt section below about stupid), professionals only under controlled conditions in boom* and fire proof locations with 25lb dry chemical fire extinguishers in abundance.
*worked once in a reinforced concrete bomb resistant structure that had chain links holding the roof on loosely. (Had to jack the roof back into place after big storms) Who knew the Maple street roldgold pretzel factory was explosive?
