     // @Description: If battery wattage (voltage * current) exceeds this value then the system will reduce max throttle (THR_MAX, TKOFF_THR_MAX and THR_MIN for reverse thrust) to satisfy this limit. This helps limit high current to low C rated batteries regardless of battery voltage. The max throttle will slowly grow back to THR_MAX (or TKOFF_THR_MAX ) and THR_MIN if demanding the current max and under the watt max. Use 0 to disable.
