I want to add a second House battery to my Freedom Elite 30FE
All,
How do I decide what battery to purchase as a second battery for the house. My RV is 3 months old. Is there a requirement to "Match" the batteries. Note sure how to get started here. I boondocked and my heater pretty much exhausted my house battery the other night and I have some boondocking adventures coming up and its going to be colder then it was when this happened. What is your advice/recommendations?
Thanks
