So I’m looking to get 2 new boat batteries. I have a 19 foot Boston Whaler, I need to power regular equipment: bilge pump, bait pump, wash down pump, vhf radio, fish finder, and stereo. I currently have two interest group 24 deep cycle batteries liquid. I was thinking I might step up to something more sealed like an AGM. I don’t have an endless bankroll hoping to spend less then $400 total. I need to stay at the group 24 because I’m hoping to get a 24 volt trolling motor at some point and need the space for two more batteries. I’m confused do I get deep cycle or starter, or the other mixed one.
