Batteries to bus bar cable size

I need a quick sanity check. I have 3 12V batteries I'm planning on going to Lynx Power-in (parallel). I am adding a 1500W inverter. Looking at cabling, I should be using 2/0 cable for the run from the Power-in bus to the inverter (200A max). But am I correct that I can use 1/0 cable going from each battery to the Power-In, as the amperage should be evenly split between each battery? Each battery will have a 150A breaker on it for extra protection and power-shutoff options.
