Proper bus size for paralleling 7 or more eg4 power pro batteries

[Ttdf12]

I have 5 eg4 power pro all weather batteries in parallel on a 2 Victron Energy Lynx Distributor | 1000A | M8 connected in series. I am thinking of adding 2 more power pro batteries to make 7 total in parallel . I am using 2 15k solark inverters in parallel.
Can I just add a third M8 in series and connect the additional batteries?
How many batteries can I add to the 1000 amp victron busbar?
Would I need to increase the size (amperage capacity) of the busbar ?

You should stop, when it starts looking really silly.

Would I need to increase the size (amperage capacity) of the busbar ?

Only if you increase the total charging amperage or load amperage, above the rating.

When the Lynx looks like the human centipede you stop, I think that’s like 6 or 8, I forget.
