Back to the the water description:
In fluid power, we rate flow in gallons per minute. In electricity, it is measured in amps. In fluid power, pressure is rated in PSI (pounds per square inch). In electricity, it is measured in voltage. In fluid power restriction to flow is called resistance, and can be measured in PSI. In electricity, resistance to flow is measured in OHMs.

SO:
Pressure=Voltage
Flow=Amps
Flow resistance/friction=OHMs

If we took say 10 L/G batteries and hooked them in parallel (+:+)&(-:-) then we would still have a 12V system, but a much higher amp rating. If you then attached them to the starter it would have (basically) an unlimited amp source. The starter still has a maximum efficiency that it can go. Once that is reached, it doesn't matter how many amps are available, it can only do so much. Just like in fluid power the motor is subject to it's size, no matter how much fluid it has available. Now, if you increase pressure (voltage) you can "push" more power to that starter (or motor) but then the mechanical limit of the device (starter or motor) will be reached and it will eventually be overcome (fail). A starter will simply burn up, and a fluid motor will literally break.

Very good explanation "Professor" Jon.
