I am looking to shed some weight in my 16 ft Riverhawk Pro-Caster. The itself boat weighs only 220 lbs. I now have about 150 lbs of batteries. I have two group 27 batteries that power my Minn Kota 80 lb Terrova. When I upgraded to a new Humminbird Helix 10 Mega SI , I added a group 24 (46 lbs) instead of the small tractor battery I had always used. I feel like the group 24 is too heavy and overkill just to run a fish finder and crank my 20 HP Tohatsu motor. From my reasearch, it appears that a battery like the one below (12 lbs) would work. Would it?
