Battery Leads and Resistance

[DampRobot]

I was having a friendly argument with a friend on the team today, and was hoping that I could get the CD perspective on our topic of discussion.

Is it best to keep the leads between a battery, the 120 amp breqker, and the PDB as short as physically possible, or does length not reall effect robot performance? We had to change from about 4" to about 2.5' leads on the 120 amp breaker today, and were wondering if that extra wiring would make a significant difference in performance.

We measured resistance of .06 ohms across both our old and new (longer) leads for the breaker. This rather surprised me (considering resistance should be proportional to wire length), and would indicate that wire length doesn't matter in this case. On the other hand, I've personally talked to teams like 254 and 971 who keep their breaker leads super short to reduce the resistance in the wires to the battery.

To pose the question simply: do long breaker leads effect robot performance?
