So I have my 32 304ah cells (2 banks of 16), the hardware they sent with the cells (nuts, studs, and bars@90*20*2mm), and I have my 2 Daly 48v/300a BMS. Are these bars enough to supply the 300a max draw on the cells without significant resistance? Does each bus bar going from cell to cell need to be able to carry the full 300a since they are in series?
If my calculations are correct using the below formula, and I'm looking to use common copper c110 flatbar, it seems the minimum size I need would be 3/16"*2" (this should give me just under 300a). Since both banks are being paralleled I rarely think my bank will be drawing 580a of draw).
4.7625mm*50.8mm=241.935mmsq*1.2=290.322a
It seems the bus bars sent are only rated for 48a
