Battery hook up

I would suggest putting the batteries, bus bars and breaker inside of an enclosure of some kind, if only plywood. If both batteries are 48V and they are connected in parallel using bus bars and there is what looks like a breaker on the positive wire then in theory it will work. In practice we don't know because no information regarding wire size, breaker rating or bus bar capacity was given. 6500Watts will require input current of up to 150Amps continuous.

Assuming that everything is up to spec with wiring inclosurs and all. The battery is 48v with a bracker on the positive. I just wanted to know if connected this way it won't cause any problems.
The two positive wires from the batteries to the positive bus bar need to be same length as each other.
The two negative wires from the batteries to the negative bus bar need to be same length as each other.
Make sure all of the wires are 2/0AWG and the breaker (you should really use a fuse, not a breaker) should be 200A or 250A. Make sure the fuse (or breaker) supports at least 60V or more. 70V or more would be much better. If those are LiFePO₄ batteries then use a Class T fuse. If lead batteries then an ANL fuse would work.
Make sure the two bus bars support 300A or more.

They are the eg4 server rack battery and the braker I got was recommended by signature solar with the eg4 6500EX inverter. I want to expand on my system and wanted to know if doing the battery connection that way is possible.
