That is what I mean, you understand it right.
Let me ask you about the loads which are used.
What resistance do these motors have?
Do they really have inner resistancies in the milliohm range?
Do you have more specifications of such a motor?
What is the typical discharge curve of a battery when it is used for
maximum current in real use?
For example if you take out 50A, for how many seconds does the battery
As I understand it we are talking about the size of cells which are
used in consumer electronics, like R14 and R20. (?)
They cannot last for long at those kinds of currents.
