LS Alt Charge Wire

I currently have my battery mounted under the bed behind the cab on the driver's side. I ran a 1/0 welding cable to a 300 amp marine grade breaker, 1/0 from breaker to the alternator charge terminal, 1/0 cable from charge terminal to starter solenoid. I see plenty of diagrams showing the alt wired between the battery and starter. Any issues with doing it as stated above? Seems fine and starts /charges perfectly (have started numerous times on the rolling chassis). Just didn't want to fry the alt post or something. Not a DC electric pro!

Voltage at all points reads darn near identical / not much voltage drop to speak of at all if any.

I will be running a separate 6AWG welding cable circuit from the battery that will have its own protection to a junction block for powering the ECM, main fuse panel inside, and other accessories. Each circuit off junction block will also be properly protected.
