Hey guys I recently got a new little boat with a shakespeare 12V T34 34lb motor. All I need now is the deep cycle battery(DCB) this will be used only for trolling as the boat has a main 5hp mercury motor that will be used to cover the large gaps. I'm a little confused as to what would be the best DCB to get I would be using it at most once a month or every second month and it would only be used for the day it would be turned off when not in use. Pls could u suggest what size to get AH? And the brands and any places with specials at the moment. Thanks
