Servo Problems

So I have two servos.

http://www.pololu.com/catalog/product/517/specs http://www.pololu.com/catalog/product/516/specs

The one with 13kg-cm can carry MUCH more than the 42kg-cm. And that's wrong, right?

I'm guessing it's a power related issue, so how do I connect a separate power supply to each servo?

Thank you VERY much all help!

I just uped the amperage on my batteries and put in a cooling fan. Works great with my 30 servos that I am running. Four are heavy duty.

How did you "uped the amperage"? And how did you connect it?

And do you have servo controller cards connected to the ez-b since 30 servos are more ports than it has?

Thanks!

I bought a battery with more amperage. I use the EZ-B to controll all the servos. I connect them directly to the EZ-B and I have 2 EZ-B's on board.

How did you connect the external power?

I use a 11.1 volt 2200 mAh Li-po battery conected directly to the EZ-B so I am only getting 5 volts to my servos. If you want Higher Voltage connect the external battery to the + and - on your servo and the signal wire to the EZ-B. You should also ground the two batteries together.

Thank you so much! I finally got my heavy duty servo to work! :)
