Power board built
The new power board has been built. I am waiting on the mil-spec wire to be delivered to finish it up though. That copper bar across it provides the necessary electron path to move 100A across the board. The resistance across the board is ludicrously low. In fact, it is beyond my ability to measure (and I have good equipment). That said, theoretically is should be 3.645×10-6Ω or 0.000003645Ω.
