The RS775 as rated for 12V operation (which is how we are using it) has a stall current of 86.7 amps and a stall torque of 112.84 ounce-inches.
If stalled at 20% of this rated torque, the voltage will be 20%*12 and the current will be 20%*86.7, so the input power will be (0.2)(12)(0.2)(86.7)=
41.5 watts, not 300 watts.
Even if the OP meant 20% of the 18V stall torque, the power would be (0.2)(18)(0.2)(130) = 93.6 watts.
