Most can handle 6 to 7 cell NiMh, which coming of the charger can be well above the voltage of a fully charged 2S LiPo anyway. The current peak will be higher, as the LiPo has much less sagging compared to NiMh for instance. So the ESC may run a little hotter, as well as the motor. But the ESC doesn't care what battery chemistry is hooked up to it. As long as you make sure there is some low voltage detection, simple way is to use a monitor that signals with leds and sound when voltage gets low. These can be plugged on the balance connector, or wired directly to the ESC to battery wire-connector, whatever you prefer.
