R indicates a resistor across the main terminals of the contactor.

Why not put the charger in the battery box before the main contactor?
Then you only have mains going in and HV coming out of the box.

I have some lower current HV connectors and 4 m of cable which can come directly from the battery pack. I just figured if I'm going to be putting a contactor in series with the charging leads, I might as well use the same one as the discharging leads. Anyway, the charger is the size of a small briefcase, so It probably wouldn't fit.

With mains coming out of the box small 240V Relays can be used to isolate the mains and the car is HV safe while charging.
Unless the charger can go in the battery box its best to have the contactor(s) on the HV lines as you have drawn.
