Ok I’m getting ready to upgrade the setup on my [email protected] Boondock, as the marine battery is pretty much toast. I have the factory solar system and the Norcold 12v. I want the best bang for my buck without going overboard on price. I have found an AGM 12v with 100ah for $500, or I could go with two 6v golf cart batteries (not sure what kind of battery, but they are rated at around 130ah each) in series for around 400 for the whole setup. My concerns are: 1) I want it to fit in the stock battery/ propane box, (2) I need about 4-5 days of good run time off grid with minimal generator assistance in good weather, and (3) want it to be compatible with the existing VictronConnect charge controller that comes with my [email protected] In other words, I’m trying to do this on a budget and yet still maintain a good degree of sustainability and minimal worry. If anyone has any battery recommendations without heading into the price of the Battle Born batteries, please feel free to post those up as well. Thanks, I need to get this done in the next couple months to prepare for some upcoming ventures.
