Good Job on keeping everything nice and clean! I love the look.
I do have one question. I see that the 6AWG going to the breaker panels are not using the SLU-70 terminals that are supplied in the kit. From my interpretation of the rules and investigation, I thought that they were required a) on the battery, b) on the main 120A circuit breaker, and c) on the circuit breaker panel.
Is this an incorrect interpretation? I would be ecstatic if you said there was a Q/A answer saying that we could use other connectors, but it seems that <R48> (and the associated graphic to <R48>) says otherwise.
Looking forward to seeing the rest of your bot
