True, though the battery plays a role. It can act as a current limiter, NiCad and NiMh can handle much lower peak currents, because voltage starts to sag then. This limits overall power that the battery can deliver to the ESC and the motor. A LiPo can handle much higher peak currents, with voltage holding up better. So you can get higher current running through the motor and ESC than with a NiCad setup, and motor and ESC can run hotter as a result. Apart from observing low voltage, it's wise to also check motor and ESC temps.
