4 gauge wire from batt to main breaker, dont u think thats a little extreme? Not to mention probly a pain to work w/
I can understand being worried bout the losses of resistance if u are working w/ somthing that needs a certain range of resistance to work, but this is a robot not some sort of sophisticated industrial equipment.
when u actually figure it out the losses in power/ supplied current is very small.

i mean FIRST regulates that we use 6 or 8 i believe from the batt to main breaker. Lets say 6 for arguments sake and if u figure out the resistance of the wire based on that ur talking about one ohm per 2,000 feet. So in my mind theres not much to worry about unless ur have a major problem w/ the wire overheating to the point where the insulation might melt and cause problems.
So why waste the weight using larger wire? thats jus less weight that u have 4 the rest of the bot. w/ the battery counting in weight (as of now) we only have 117pounds to play w/ in terms of robot weight, so why waste weight on needless wire?
