IIRC, I do not believe so, but Patrick has said there is a thermal shutdown. But if the increase in temps happens too fast, this circuit doesn't have a chance to shut things down before catastrophic failure.

Besides, a current limiter would have to measure current to work right, and that would involve either measuring voltage across a shunt, or some type of feedback device, both of which would introduce resistance, size, and expense into the circuit. The only other way I can see to do this without those losses would be to monitor the input battery voltage and back off the throttle if there is too much of a dip in voltage.
