Whos' right?

A friend and myself were having a discussion today about batteries. He claims that if you run a higher mah battery you will have more power. I said if you run a higher mah battery you will get a longer run time. Who's right?

You are.

If the current demand of the motor exceeds the capability of the battery pack, then switching to a higher capacity pack will BOTH increase your power and your run time.

If your pack is able to keep up with the current demand, then increasing the capacity will only increase the run time.

How do you know if the battery pack is big enough for the motor? Is there a general rule of thumb?

compare the current draw of the motor to the discharge rate of the battery. (use the motor wattage and your voltage level to determine current) i always stay well above it.
