Such a soft failure would be concerning. One BMS that I am intimately familiar with has two thermistors, one stuck to the batteries using a plug and a short cable, another surface mounted on the BMS board, if the delta between the two gets too large it shuts down any charge cycle in progress and bricks itself. Pretty harsh but given the alternatives it is the only safe thing to do.

Oh that’s a nice redundancy, glad to know, I’ll probably check for those when i open battery powered stuff from now on
