6 x EG4 LifePower4 - Longer conductors or larger busbar?

[jarred125]

I have six EG4 Lifepower4 batteries now (had 4 before). The existing four were connected using the included conductors that are 12" long. However, adding two batteries now means that at the extremes the included conductors will not reach.

Busbar: https://signaturesolar.com/600a-12-stud-busbars-red-black-kit/

Would it be better to just buy longer conductors (if so, im thinking 24" @ 4 AWG), or would you source longer busbars? If longer busbars, does anyone have a good source for materials?

How do you have your batteries connected? Picture?

Each is connected to the busbars linked in the OP. Negatives to one, positives to the other, then a 4/0 copper conductor from each to the Solark 15k inputs that are linked with bus bars to allow the full amperage.

Currently the conductors going from the positive and negative terminals on each battery, then to the bus bars linked above is the 12” 6AWG they come with.

After I thought a bit more on this and did some voltage drop calculations I will be fine with 2' conductors from each terminal to each bus bar.
