Yes, you can. Just make sure that you only connect the downriggers to a single battery(each) and the trolling motor will be hooked one wire to to + on one battery and the - on the other. The downriggers will be hooked to the appropriate + and - of their individual battery. You will have more than one wire coming off each terminal. This is tougher to explain than it is to hook up.
