I know very little about setting up a trolling motor and was wondering about batteries. Do I need a separate battery from my boat battery for my trolling motor? Also if i need a separate battery do I need a charger? How does the charger work? Thanks a bunch.

Yes, you will need additional batteries to run a trolling motor. One battery if the trolling motor is a 12 volt system and two if it is a 24 volt(three for 36 volt). Your main motor battery is or should be a cranking battery. You will need deep cycle batteries for a trolling motor. As for chargers, the best way imo would be to get an on-board charger installed. This allows you to charge all batteries in your boat by simply plugging the boat into a wall outlet like those found in your home. You could also get a Schumacher individual charger from Wal-Mart for around $45. I used this for years with no issues until i discovered on-board chargers. Oh yea, don't forget to add a fuse to the + side of the trolling motor to battery wiring. Best of luck

All it takes is one session with a paddle in your hand. Your question will be answered.

Seperate battery(s) for the TM.
