Monitoring battery banks

A customer asks me to monitor one of his battery banks. There are 12 batteries connected in series and parallel, their operating voltage is 24 VDC, the idea is to place a SmartShunt every two batteries so we would measure 6 battery pairs, but the Cerbo gx only has 3 VE.DIRECT connections, so I would like to know if you can connect two Cerbos gx in series or parallel, or if there is a better way to measure these 6 battery pairs

You can use ve direct to usb cables.
And a good quality powered usb hub if even more is needed
PS add battery balancers as well
How are you intending on wiring them?

@Dignosyvalientes
Did you consider buying a asupported BMS like Daly to measure the batteries?
Might be a solution, depending on your batteries.
