1/0 is generally considered too small, and 4/0 is probably too large.  
Using mixed cable diameters is not a good idea, but probably ok.  4/0 is 
rather hard to work with.  My recommendation is use 2/0 for the 
motor/controller connections.  You can use 1/0 for the batteries if you 
have it available, but 2/0 would be less lossy.
