I wouldn't recommend using the Nissan Leaf busbars in pack locations that exceed 114 amps. The bars should be fine within the series strings, which is what I meant in my prior reply. The ends of each of the 5 parallel sets should be connected some other way.
I have heard of copper pipe being crushed flat, then drilled, to create suitable custom high amp busbars.
