The QuickStart guides for the 14.3kWh WallMount batteries outline that the second battery should be wired to the first and then the first should be wired to the inverter.
One example is Figure-2 on page 10 of the Indoor WallMount QuickStart Guide.
Another example is in the 18kPv wiring diagram V1.2 (page 6)

However I have seen this similar description and diagram in other EG4 manuals.
Wiring this way will cause the Resistance to be higher for the Second battery (distance from inverter over twice as far) and therefore on a 80% DoD the first Battery commonly will achieve an uneven discharge vs Second battery.
My question: Why doesn't any EG4 manual suggest one of the cables (for instance positive) connect to the second battery instead of the first?
The two batteries would still be connected to each other using the Parallel Cables. With one having the Positive to the inverter and the other battery having the negative to the inverter.
Is there a technical reason, or would there be some side effect / long-term impact I don't recognize?
If my suggestion was a legitimate wiring scenario then the distance to each battery from the inverter would be the same - and enabling them to charge and discharge more evenly.
I have to be missing something as I haven't seen this suggested/discussed in the Forum or offered as an alternative wiring in an EG4 manual.
Appreciate your insights.
