I have a Lund Fisherman 1750 with a 24v Ulterra, and I use 2 100ah lifepo4 batteries. I have a 2 bank Noco onboard charger connected. I use my trolling motor for autopilot while trolling. Never had an issue with battery life, and can go at least twice without a recharge. I would go for the 100ah as opposed to the 50ah. You can't have too much reserve and the price difference between them is not significant. The new mini size profile is nice - I have three of these, two for trolling motor and one dedicated electronics supply
