We have a setup we use where we can plug in a 12V battery and also connect motor leads (with 'gator clips) that uses a momentary switch to energize the clips so that we can test mechanisms before we have the control systems completed.

Do use caution when connecting motors directly to batteries. Like car batteries, there can be gasses that can ignite - although less common with the gel type we use. Also, if your motor is indeed bad, it can draw extreme currents and arc badly - which is bright, hot and dangerous. It is best if you could wire use the recommended gator clips and the 120A main robot power switch/breaker. Connect the motor with the switch off and use the switch to activate.
