Almost certainly the battery, rather than the 'electronics'. There were a
number of cases a little whle ago, of 'clone' batteries (and some genuine
ones), that if mechanically distorted, could short internally. When you
discharge the energy in modern cells quickly the temperatures involved can
be really dangerous. Even worse, on Lithium based cells, once they
rupture, if moisture is present, you then get the chemical action as the
Lithium re-acts. Many years ago, large Lithium cells were used in some kit
in TV studios. I was present one day, when one started to smoulder. It was
not doing much harm, till somebody decided to throw a bucket of water over
it. Clouds of really hot steam. The fact the man was in the bathroom, may
suggest a similar scenario with water...

Best Wishes
