Wiring 5 parallel batteries with IP22 w/3 outputs

Hi!

First of all apologies for my ignorance on this topic, I'm trying the DIY :) I hope this diagram helps...

Battery charger: Victron Energy Blue Power Charger IP22 3 Outputs 12V

Questions:

Are the Positive busbar(s) correct? Is it possible to wire it like this with the objective of charging 2 batteries from 1 Victron Output?
What would be the size of the wire (AWG) I would need for the positive connections? I saw 6AWG for a distance of 8 feet. Is that correct?
Would be the size also for the wires in section2 (blue rectangle)?
The fuses should be 30A?

Thank you in advance!

Potentially one battery can take the full output of the charger, so size all wires and fuses for 30A. Hope you're not mixing battery chemistries. Otherwise looks ok.

Thanks, @kevgermany Much appreciated

Checking the user manual, I see in the section "Enclosure":

https://www.victronenergy.com/upload/documents/Blue_Smart_IP22_Charger_manual_230V/Blue_Smart_IP22_Charger-en.pdf

Just wondering if I can use AWG6 for 30A, or should I use something like 10AWG or 12AWG?

You can only go to the max size in the manual. I think you're going to find that it's a snug fit.
