If you want to juggle power management during combat than you can have this setup:

Everything A grade, two chaffs, two SCB (slot 4 and slot 2), two boosters (A grade).
Cargo hatch and SCB are hard off until you need them. When you want to use SCB, your fuel scoop, FSD interdictor, chaffs and weapons turn off. You can pack two shield boosters for 550MJ of shields and that SCBs are to make sure your shields never drop down. I used to run this setup for PvE and it's ok, you manage to do manual switching off and on easily. It's a different story when trying to PvP. You have to be extra quick.
Now I run different setup. Basically, SCB have to be online at all times. It's impossible to imagine PvP without them and you can't afford that few seconds that you need to turn them on manually.
