[QUOTE="Makaw, post: 488661, member: 25180"] Are you able to do any amp-hour estimates based on the draw ratings for your sonar and lights? My first thought would be to try and use the manufacturer data to make intelligent guesses on how much power you’ll need for 2-3 days of running that equipment. Then try and size for BOTH the CCA and amp-hour ratings of a specific battery. As DaleH suggested, a dual-purpose is a good choice. I would venture a generic 24 would be perfectly sufficient, but you could probably step up to a 27 (6-10 pounds heavier) which might get you a nice amp-hour bump. I oversized my trolling motor batteries for that reason to group 31s. They run 60lbs each, but last FOREVER. A few pounds might be worth the added capacity. Pay attention to each specific battery though, even within a battery group size there will be weight and power output/reserve differences. [/QUOTE]
