A motor rated for 18V will run fine on 12V, it will just be roughly 4/9 the power of it on 18V.
i am aware, but (4/9) times to 200 watts max power that the supplier has tested for still leaves less than 100 watts of power, unless it is the 14.4 V nominal opperation motor, in which case it will output around 70 watts. according to the people who made the motors, there is no way any of them that size will output more than 100 watts at 12 volts.



also, power is current * Voltage

according to the Bane Bots website peak efficency current is 5.7

5.7 * 12 is 68, which fits the 70 watt power output number, i think all the other info on the BaneBots website is correct, except the power calculation, think that was taken at 18 volts.
