"I used these motors to run a program that had over 50,000 lines of code; 5 hours, non-stop on + off + measuring. Even though the batteries in the EV3 brick were wearing down, the motors stayed calibrated and accurate.
These motors are less powerful than the large motors so they may not be ideal for a load as heavy as an EV3 brick, but for smaller loads, they will be more accurate with lower power consumption. These motors are impressive."
