One battery or two
I know this question has been answered before, but not for me:) Buying a new travel trailer and the dealer recommends a single 12 volt battery. We have had double 12 volt batteries on our travel t...

Are you better off with 2 6v golf cart batteries or 2 12v deep cycle batteries?
Forum pundits will automatically say 2 GC-2 6 volt batteries but that ignores inherently higher internal resistance which can cause excessive voltage drop under heavy load from an inverter. A pair of 12 volt G31 batteries, especially AGMs, will offer similar capacity but with much lower internal resistance and therefore suffer less voltage drop under heavy inverter load. Secondly, a pair of GC-2s, while taller, will also have a smaller footprint than a pair of G31s so the space you have available also plays a role. So - the answer is, it depends on your intended use. ;)
