Extra Battery

[imax48236]

If your servo needs a +9 volt input, you may want to use a voltage regulator circuit which will lower the voltage from 12v to 9v. These are readily availible at RadioShack or your favorite overpriced electronics provider.

Hope this helped.

Before spending too much time figuring out if your extra battery is legal, also decide if your servo is legal. I would say it likely isn't. Please follow the 2007 Parts Use Flowchart on Page 19 of section 8 of the manual.

<R45> Items specifically permitted on 2007 FRC ROBOTS include:
• Additional HITEC HS-322HD Servos.

I believe only HITEC HS-322HD servos are legal.

You can't put custom circuits in between the RC and any motors including servos. The servo must be directly connected to the PWM output on the RC. It already provides the correct voltage (7.2v) which comes from the backup battery.
