Narrative:

After several attempts the right engine did not start. I was concerned that the batteries were being depleted and because the aircraft was equipped with generators that do not produce much voltage at low rpms; I decided to start the left engine and taxi around the airport to recharge the batteries. I requested a maintenance taxi down the runway and tower cleared me for taxi on the runway. I taxied down the runway at moderate speed in order to clear the runway as soon as possible. As I approached the end of the runway I attempted to slow the airplane with the brakes but because the speed was too high the right side brake locked up and the right side tire blew out. The airplane slide off the end of the runway and came to rest about 50 ft off the end and about 30 ft to the right of the runway edge line. The aircraft sustained no damage other than the blown tire and there were no injuries.
