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.
The mechanical output power can be calculated from torque times speed.

If you take the motor at half free speed, it is also at half stall torque, for the 775 this works out to over 250W of power.
