More about 775 DC motors. Do they work as a generator? How strong are they?

In a previous video I carried out some tests with a 775 DC motor to show you that the specifications provided on Banggood website couldn’t be correct. Actually the results we got are way out of the specifications. Since then I’ve received some comments about the way the tests were performed and also some requests.
In this video I answer some of those questions and we have a look at what I’ve been doing to get a better understanding of the performance of those motors.
