I will have my 12 new 280ah cells Friday. Not sure of the quality of the buss-bars they send with the cells. In the event I don't like them I will make my own. With 280ah cells in 4s the current would be divided across all 4 cells, am I correct on that? If not then a 280amp buss-bar would be at least .250 thick if using 1 inch wide copper material. To me it makes more sense that it would be divided across the 4 cells so 70 amp bars so .125 one inch wide would be plenty.
