Yes, that's it. The battery is connected to the starter solenoid with the large cable. From there, it is connected to the 50 amp circuit breaker. You do it that way so the starter motor's draw does not go through the circuit breaker but everything else that draws from the battery does. All charging of the battery goes through that circuit breaker as well.

EDIT -- and it's always been there, I just consider that to be "next to the battery."
