[RE-wrenches] single string of batts: must the interconnects be inverter size cables?

Example: 12 two volt battery cells in one 24 volt string. 4kW
inverter/charger has 250 amp DC breaker size and 4/0 cables...as the
inverter folks would want.
So...do the "cell to cell" interconnect cables have to also be 4/0? In the
example above, 2/0 interconnects would suffice from the standpoint of basic
safety...and even from the voltage drop standpoint...right?
Inverter company people may be best qualified to answer this, but any
replies will be appreciated. While I'm at it: do the inverter folks request
oversize cables because they want more capacitance on the DC input...or
what?
