Im new to electronics. Im a freshman in electrical engineering and just trying to start learning some stuff on my own. I saw this https://www.sparkfun.com/products/11497 hexapod robot and I want to try and build it. I ordered all the stuff but I still need a battery to power it and Im not sure what kind I need.
Im using the spider controller recommended on the robot product page: https://www.sparkfun.com/products/11498 . With this controller it says to use 7-30V and 3A but Im not sure what kind of batter would put out that much power. Id prefer to use Sparkfun since I have a gift card for them but if there is another site that has to be used I can do that to.
