Narrative:

Max power takeoff do to an MEL restriction. At around 80 knots generator 2 fault and almost immediately after generator 1 faulted; resulting in the airplane down grading to battery power. Executed a rejected takeoff and brought the aircraft to a stop. Tried to be easy on the brakes knowing I did not have anti-skid brakes. Exited runway and rejected takeoff checklist. Tried to reset both generators; but only could get number 2 generator back on line. Once we got some power back we checked brake temp and saw the highest temperature on number 4 brake was 350 degrees turned brake fan on and temperature started to go down. Then started APU to get a second source of power. No additional problems could be found so taxied back to gate.
