    Sorry for starting new thread but couldnt find this in existing discussions. All the copper busbars that arrived with the DIY boxes and that came with the cells from NKON appear to be 40 mmsq. This seems insufficent for 280Ah cells? In my system I will have 3 batteries parralled so max continuous current of about 80A. Even that seems like its pushing it for 40 mmsq copper. Someone tell me I missing something here? How can these possibly be sufficient for prople pushing close to 1C….
