Even upgrading to AGM style batteries from lead acid will help im assuming thats what you have now. Also consider getting a on board alternator that will charge your trolling motor batteries while engine is running minn kota & power pole make them. it hooks up to motor alternator and is dedicated to charging the trolling motor batteries when engine is running so when you make a run to a new spot you could be charging you batteries right on the water. Lithiums are very nice and pricy. i did the minn kota and AGM odessey group 27s i can fish all day and still have some battery left. I just think that being able to charge your batteries on the fly on the water is the way to go.
