4/0 cable and M6 studs?

PLEASE WATCH THIS VIDEO Busbar & Wire Jumper EDUCATION and you really do need to pay attention to this... So many got pooched without understanding why and Ray really covers this point.... AVOID THE ABOVE MISTAKES AS SUGGESTED !
I watched the video and I found it a little bit amusing when he expresses such surprise that a wire sized for the same cross sectional area as the busbars has approximately the same resistance. (about a 1/0 awg to match the busbar)
 
Two 200A BMSes in series will not handle a 250A load. They would have to be in parallel. Then they could handle 400A together.
Thanks for that. I've corrected it. The OP mentioned he will have them in parallel.
