I got my Ez Robot developers Kit for making my Wall E robot. I got all the servos up in place and tried to power on the controller. I am using the Li-Po battery that is available on the the store. I connected it to the plug that goes into the controller but I couldn't get the blue lights for the controller to come on nor did the controller make any sound. I haven't used it before and this is straight out of the box. I was wondering how I can diagnose if it is a faulty part or I am doing something wrong.
