In the market for a new cranking battery. Running a Puma with 250 Pro XS, twin power polls and one fish finder on bow and one at console. Plus the usual pumps. Even when current battery was new I'd get a power drop late in the day to the bow fish finder. Currently running an Interstate Cranking 27m 800 cca. 1000 mca.
Given the limitation on space adding a separate battery to run accessories isn't an option. So is there a better option than a standard cranking battery to start engine and give better performance all day running the accessories?

Thanks.
