Here is the set up: A Minn Kota PD 55# which is 12V, 2 depth finders and my bow and stern night lights. I was wondering what kind of battery set up I should look for. I have a 14' Aluminum Deep-V, so there is not alot of power needs such a bilge pump, starter, etc.... Should I have a seperate battery for the trolling motor or could I run all of this and get away with a bigger battery.
