Sizing a battery bank. Ah VS wh?
Hi again! So, I'm trying to size out the battery bank I will need for my husband and I to live off grid in a camper. We don't have tons of time or money, so that's a bit of a factor. We plan on usi...

You haven't watched or read nearly enough it sounds like. I have said many times. if youre going to camp. learn to camp. there are a whole world of camper items, and kitchen camper items that are made to work when camping because 120 volt AC current is not always available and will come at a HUGE premium when you have to make it yourself.
On batteries. 6 volt GC batts are talked about a lot bc they are true deep cycle batts. Marine batts are not true deep cycle. there are true deep cycle batteries other than what Autoparts store sells, but you pay more.
General consensus is AGM is a terrible waste of money for an RV.
Two 100 amp hour 6 volt batts run to make 12 volt will equal 100 amp hours.
Two 12 volt 100a/h batts run together to make 12 will equal 200 a/h.
The one watt for each amp hour on a battery sounds about right. You could go two even to be safe as solar panels really are going to to be the cheapest part in the long-term.
Watt hours is a better way to think than amp hours, but amp hours terminology is hard to make go away, learn both.
What are you running or plan to electrically?
Yes, 24 volt can be an advantage under certain circumstances, but will make things more complicated. I have a compressor fridge that runs off either 12 or 24 volts. It is the main electrical draw. I would go 24 volts if I were to do it over again just for the fridge and then make 12 volts for the other RV items off of whatever converter is needed. Unless you have a specific 24 or 48 volt need then stay 12.
