distributed batteries

background: i dont have all my space in one place, for the batteries.


am i allowed to do something like this in the pictured wiring diagram? you'll notice i can fit my first 2 batteries nearby the distribution bar (1000a) (0.5m)

but the next pair of batteries will need to be further away (3m). and the next pair of batteries (potentially) the same distance away again (3m).


batteries : i am intending on powertech us2000c - 48v.

thanks @Matthias Lange - DE

so as long as i do that, then i'm ok with the lengths of material 'copper' wires being slightly different


because of this diagram, which shows a different length of material wiring for the black cable.
