The Victron B2B unit is excellent, you will charge your batteries much faster and more effectively with this device, which can be important when a drive is your only means of topping up your leisure batteries. The Victron B2B will charge at up to 30amp.
I use a Sterling Power B2B which charges up to 60amp so I use a thick cable which is actually welding cable and is a little more expensive but not excessively expensive. It’s also ideal if you have a long cable run (less voltage drop). A cable supplier did suggest a 10mm cable but Sterling Power don’t agree, I won’t say who is right or wrong but I played safe and went heavy duty. (I did once trip a 70amp fuse which was my fault as Sterling recommended 80amp). Below is an image showing the thickness of my cable from vehicle battery to the B2B.
Hope this helps you.
