If you go to the battery tender web site it has multiple versions of wireings of multiple batteries whether in series or otherwise.

Extra Battery

Why would you require an extra battery. I am new to Jayco and was wondering if I can learn what an extra battery will do.

In a motorhome, you have "House batteries" and you have the normal battery used to start the vehicle.
Some motorhomes use two - six batteries as "House Batteries".
Depending on how they are wired, you will get longer time running your interior lights, microwave, fridge etc, etc......
You will still have 12 volts DC power, but more current or power to use accessories longer.
You can do the same in any trailer. If you do a lot of "Boondocking" or "Dry Camping", you will want to have more than one battery because you are not connected to shore power.
If you would like more details, please PM me. I can give you more info.
