In order to carry the current I need, I am planning to upgrade the cable between my batteries (100 Ah & 100 Ah)
and my inverter (1500 watt/3000 peak)
from 4 awg to 2/0 or 4/0.

My question: Do I also need to upgrade the cables between the two batteries?

    to put it simply, yes you should. interbattery connections should be at least as large as the largest sized wire used anywhere in the system and i like to double that if at all possible to minimize potential differences between the batteries even further.
