Arduino Braccio Remote Power

Hello, I am trying to power the arduino braccio robotic arm without plugging its adapter into the wall. I tried powering the shield that sits on top of the arduino with a 9V battery similar to how you would power the arduino base, but the red error led lights up whenever the shield is powered on. I'm guessing this is because 9 volts is too much voltage for the shield, but I'm not sure how else to power the arm without plugging the adapter into the wall. Would a 5V battery work better for this situation? Any help would be appreciated.

Some more information: the power supply that comes with the braccio is 5V, 5A and I have 2 SR 311 and 4 SR 431 servos hooked up to the shield.

If the power adapter that works is 5V 5A, then you should replace it with a 5V source that can provide at least 5A. Your 9V batter is not that.

I have used larger higher voltage batteries and a switching voltage regulator to power similar projects.

Applying too large a voltage can completely destroy electronics - never do that!

Anything powering motors will need lots of power, 9V batteries cannot do that...

Thanks for the reply. Do you have any specific batteries to recommend? I am using the Pololu 5V, 5A Step-Down Voltage Regulator (https://www.pololu.com/product/2851).

Anything more than 6V and less than 38V, that can deliver sufficient current. These voltages are listed on the specs for your regulator. A 12v automobile battery would work. A battery from a cordless hand tool would work. A series of D alkaline batteries would work. A series of AA alkaline batteries would work but not as long as the D batteries would. Any number of RC hobby LiPo batteries would work, 2S up to about 6S. You would need an appropriate LiPo charger.
