Yup just plug it in for about 10 years I carried a 60-70 lb trolling motor battery to  charge in cabin every night then back to the boat in the morning total PIA. Then about 5 years ago I got a 2 bank on board charger what a relief just plug it in to the pier or in your garage and your good in the morning. As far as installation it's real easy. 

No,all I do is plug it in and its good, two or three bank is the only way to go.

If I purchase a two bank on board charger and install it on my boat do I still have to disconnect all the wires to charge the batteries or does that somehow bypass having to disconnect the wires. It's a 24 volt trolling motor and know you have to disconnect all the wires to charge the batteries but not sure if that's the case with a two bank charger? Thanks for any suggestions I'm not really good with electric lol

the breaker is also a shut off switch so I just kill the power and charge one battery at a time. For now until I get a two bank charger 

Looking good... I did the same thing... Power drive 24 volt 70lbs 60 inch shaft...I went will 8gauge wire and 50 amp fuse..love it on my 18 foot StarCraft smf..just remember disconnect all wires for charging unless you have a 24 charger.. I have 2 12 volt charger.. good luck be safe on the big pond keep them tight and watch out for wing dams on the Miss.. Wash Tub over and out.. Semi retired and the castle rock..

Finally got the boat upnorth and on the water and the trolling motor works great. Plenty far enough below the water line that it doesn't blow out which I'm sure it will in big waves or wake.  But I don't fish in them conditions usually unless on lake Michigan but then I don't use it anyway. I mostly fish inland lakes and Mississippi backwaters. So I'm very happy with it so far and  yes everything is properly wired in series with proper gauge wires and 50 amp trolling motor breaker. Thanks again everyone who responded appreciate it!

Got it all Mounted and wired up just gotta go fishing and try it hopefully it works good for my boat! Thanks to everyone who responded for their help!

Thank you for the info appreciated 

This is what you have described and is correct.
