This is a guess.
I imagine that the speed controllers do not behave themselves under a low voltage condition and powering off the 7.2 was the lesser of two evils. With so much current being sucked from the main battery, low voltages are almost guarenteed. The speed controllers are driving the most powerful motors on your machine. Keeping the internal logic alive and stable when the main 12V power dips is a primary safety concern.
