Thermal cutout.... The Makita batteries supposedly have that/current limiting too, but that didn't stop someone from making my SDS smoke last week when he stalled it and managed to drain a fully charged 4AH battery in less than a minute. Drill still works fine, (or appears to), but I'm guessing its lifespan hasn't been helped any.
