BMS has pairs of terminals. How to connect?

[Aphers]

I'm building a 4S 280Ah bank using a 200A JBD BMS.
Unlike my previous project, the BMS has two M5 holes for connection on each side.
I'll be using 70mm² cable, connecting to the single stud on the battery, and to the shunt on the other side.

Do I:
- ignore one of the terminals and just run a single 70mm²?
- make up Y-leads using two 35mm² cables, in to a single lug at one end.
- run two 35mm² cables and stack them at the terminals
- something else?

If you have determined you need 70mm^2 wire, I think it follows that your connection area around the M5 threaded holes and ring connector(s), must be at least as big.

Here's something else (yea it's overkill but I had some scrap pieces) . The tape makes a great template...
