I purchased my first bass boat this summer. when I got the boat it was all in working order with a 55 pound 24v trolling motor, that just wasn't cutting it. I was shopping around and ended up getting a good deal on a minn kota maxxum 101 36v. Now im in the market to get a 3 bank charger, and Im going to get all new batteries. with that being said Im looking to for some info before I make my purchase. I was looking at the dual pro sportsman, I have been told that that's the only way to go for your charging needs. just looking for a few more opinions. As far as batteries are concerned, im pretty uneducated as to what the differences are. I have a 1989 astro quickfire 18gt, and I fish her pretty hard.
