Also, I seen a few Lithium battery upgrades that included a high amperage charger, but they didn’t install heavier gauge conductors. That can create a fire hazard in a hurry…
I have a very good dc converter, which I have always trusted implicitly. It does get warm after running for a bit, but it also also has a very good cooling fan. I tolerate the fan noise, because I know the fan protects the device. The possibility of a fire originating here has never occurred to me. Silly me! My question is, isn't there probably thermal shutoff protection built in to these devices?
I think these converters go into current limiting rather than thermal shutdown.
It would be an interesting experiment to take a 12-volt battery and intentionally short out one of cells and then see how a charger reacts. I assume that a FLA battery would boil out the electrolyte in the remaining cells, with a hydrogen/oxygen explosion from an internal spark. But that’s just a SWAG, not a real theory of failure.

Another dead cell=full charge runaway.
That’s certainly a possibility.
