Lithium batteries can catastrophically fail for a number of reasons. Internal shorts from discharging too low, external shorts, over charging, over discharging, physical damage, and heat to name a few.
If your charging circuit isn’t balance charging the cells properly or the overcharge protection fails, then it can cause many of those issues to happen much faster.
Moral of the story: never leave a charging battery unattended.
