DC\DC Charger wire size recommendations

Please could I have a bit of advise on the correct mm2 wire to use in the below.

I am installing a 30amp DC to DC charger in my trailer, the distance between the car battery (source) and charger is about 7m and the distance between the charger and the auxiliary battery is about 3m.

What size cable should I use for the 7m run?

What size cable should I use for the 3m run?


thanks
