What kind of condition are the batteries in?
Do you have a budget?
I'd rip out the wiring and start again. It looks like an accident waiting to happen. Some of the crimps don't look great either. Buy some quality cable. 2/0 is a little overkill but a quality, thick (50mm2+) well insulated cable is a must.
Get some propper lugs, they're cheap as chips. Then buy or borrow a Crimper and make the cables. Ebay is a good source.
Keep your high voltage, high current cables closest to the base of the battery or terminal post. Don't separate with bolts, washers etc. Other cables can then be placed on top.
Sort out battery clamps to stop them from bouncing around. Check out my build thread for a cheap and simple way to clamp them down.
Add a precharge resistor as tesseract suggested
I'd be tempted to pull the motor and give it a good clean up.
Hope this helps,
