I do not have a battery rack with buss bars in it so I can't use the short #4 cables that come with the batteries. I have two batteries and two inverters in split phase for now and the wiring needs to be about two to three ft long to the buss bars. Is #4 cable still ok with the added couple of feet in length and do the battery cables coming from the batteries Before the buss bars have to be equal in length as well as the cables coming from the buss bars to the inverters.
