Should the wire I use be able to handle the stall current of my motors? Answered

I am building a battlebot (3lb), and I was wondering if the wire had to be able to handle the stall current of all the motors, or just the normal current that the motors draw.

Usually that's not too big of an issue. Most motors are hooked up so that if the motor stalls a breaker flips. So the wire only has to handle the current for a short while.

But in a battle bot there is a good chance of having it stall often so I would go with the much larger wire.  You get the benefit of more running current in the bargain.
