Haven't posted anything in awhile, but here goes. I am building a houseboat and will transfer my small two panel system to run some items on the houseboat. Looking for recommendations as to what batteries to buy for a 24V system. I know the first question will be what do I intend to use it for so I foresee using it for lights, TV, demand water pumps, etc. when the genny is not running. Don't want to break the bank by using lithium-ion and I really don't know if it would work with my controller anyway. I'm thinking small, like two 12V batts in series either flooded or agm, probably group 31's. Looking for advice on brands, businesses, amp hours, etc.

For a wet area I would go with AGM type but remember they may not last as long as an Li chemistry type battery but will be cheaper.
As for the size. It depends on what your panels can generate in amps. A Lead battery requires about 1/10 the amount of Ah the batteries are rated.
As for brand, my guess would be ones that are not expensive to ship to you.
