As long as you get a digital/smart battery charger, you're ahead of the game. IMHO

If you're cramped for space to mount the charger, check out NOCO Genius Genpro 10x2 ($200/Amazon) (*they're made in USA, if that has any persuasion on your purchase)

I have a Minn-Kota 220 in my boat, but only because it came with the boat when I purchased it from a friend. My buddy has NOCO chargers in his boat, and I just got a friend to purchase a NOCO for her trolling motor battery on her pontoon. IF my MK220 ever gives up the ghost, I'll probably replace it with a NOCO.
