Usually you get a very small PCB connected to your battery poles, that has three leads.
It's a protection circuit with at least one chip.
I've only encountered thermistors with battery packs and even then they are connected to the balance board.
I did find loose thermistors with Nickel cadmium battery packs from powertools and robot vacuum cleaners.
