I have a 2007 Seaswirl 175 Fish n Ski equipped with a Minn Kota Powerdrive 65lb bow mount trolling motor. The boat has two 12 volt batteries dedicated for the trolling motor and one 12 volt for the outboard/accessories. The only access to the trolling motor batteries is completely removing a built in tackle storage box to gain access for charging. Can I wire a Battery Tender to a trolling motor plug and plug that in the bow?.
