Adding a 2nd positive cable to battery

[Trekster]

I’m going to install a victron DC charger to my van which already has an additional cable on the positive terminal.
Should I change the terminal clamp for one which will take an additional positive cable (see pic)

Welcome.

You can fit as many additional cables that will fit under the nut as long as you use a ring terminal of the right size.
