If you think of a campervan.
One battery is for the main car engine. The other is the leisure battery and is used to get the fridge, water pump,lights etc going so they do not drain the main one.
We have a folding camper. We have a leisure battery. If we wanted to go into a field wanted all the above to work the electric to run them comes from the battery, through the zig unit and that gives us the power to run them. Without running down the car battery.
We can charge the battery via the cable that we plug in on site and the charger inside the fc switched on will keep the battery charged up. Leisure = leisure things
You will get more info from others when they come on I am sure.
The fridge can't be operated from the leisure battery, it's either gas or 240 volt mains that runs the fridge. It's only 12 volts power when it comes via the towcar electrics when the trailer is in tow.
