Pylontech wiring with more than on cable pairs

[pilotmicha]

Hello everyone,

I have a question for the Pylontech specialists regarding the wiring with original Pylontech cables.

As a maximum of 4 x US2000C batteries may be connected to the busbar on one cable pair (max. 100A), I have provided 2 cable pairs for 3 US2000C each.
Variant 1)
Plus and minus are connected crosswise with both cable pairs to the first and sixth batteries.
Variant 2)
Plus and minus are connected with one cable pair crosswise to the first and third battery and the second cable pair is connected crosswise to the fourth and sixth battery.
The communication cables are connected in series in both variants.
Which is the “more correct” variant or does it not matter?

I think this is a more general battery question, rather than specific to Pylontech. I haven't seen any advice from Pylontech regarding using multiple cables.
