Power in electric motors is directly proportional to current and voltage, if you reduce the Voltage you reduce the current and subsequently, the Wattage.
Purely for the sake of argument;
A motor rated at 10A@10V will produce 100W.
Half the voltage and you halve the current, so now it's getting 5A@5V which only produces 25W.
It works the other way as well, double it and you'll get 400W (and a small rotating cooker
)

Thank you some one understands!!
With this scenario there are two ways at looking at it, and with R/C stuff if the voltage is dropped then the overall power is dropped hence less current.
The main reason mod 4 cell not working or very close to dumping is that they also changed the amount of turns at the same time i.e 5 turns. Less turns, less resistance higher amp draw.
