Doubt about battery tower connection

Hello, we have a question, we have recently installed 4 Pylontech US5000 battery  with a capacity of 100AH each (400AH in total). 

The four are in parallel and we have thought that the 35mm paylontech cables are scarce since they would only hold about 70 AH of discharge. 

Do we put the batteries two by two to a busbar where they join or do we put the first and the last with two cables each?

What size is your inverter(s)?

Pylon cables are rated to 100A - the installation manual from pylontech has all the specs and cabling recommendations.

You need to size for the system current you intend to pull, so if the inverter is small you don't need to over-cable.

It is common to add a second feed to the stack like pylon show in their docs, see below.

Otherwise, multiple stacks to busbars, really depends what you are running.
