I did have two, they were linked together  under my OS settee , I took one out last week as I am going for one big one. to free up storage space.
Make sure the cables  are  thick enough.
Regards
Margaret

Wire as in the diagram 'separated 12v batteries in parallel' using 25A fuses and 6mmsq wire.

The batteries can be physically separated (mine installed as original by AS are 6m apart) but are much better close together.

"Paralleled batteries are best if they are of similar age, ampere-hour capacity and construction. That is, one does not connect a Maintenance free (Gell or AGM) battery in parallel with a wet electrolyte battery. Indeed if one wants to fit two batteries in parallel its best if they are purchased together as a pair."

I recommend that you do not have the capacity of the two batteries differ by more than 20AH or the age differ by more than 2 years.
