I believe he wants to know best battery for pulling crankbaits, what will have the longest run time for one day ,if u have never pulled crankbaits u wouldnt u understand.i run two seperate 24 volt setups so i can make it a full day no problems,pulling at 2mph for hours straight is hard on.batteries and wireing, i even melted some quick disconnects together one time.when u pull cranks ur not worried about how many years u can get out of a battery, ur just worried about how much runtime u can get in a day.
