Motor Feedback

Does anyone know what the current and power motor feedback values are measured in?
Thanks

According to V5 API https://api.vexcode.cloud/v5/html/classvex_1_1motor.html
current() returns percentUnits of the max allowed current and power() returns powerUnits = watts.

Max motor current is 2.5A or 20A/number_of_motors, unless you explicitly set lower limit for any of them How does the decreased current affect the robot when using more than 8 motors
