I'm exploring a similar deal for my drift boat but after talking to numerous friends who have the same, it looks I'll be looking at something in the 24 volt(2 battery) 70-80lb thrust dept. Everyone I've talked to and everything I've read says spend the money on a good charger for the reasons stated above.

I have a question though. If I go with a 24 volt, 2 battery setup, how do you go about keeping them "maintained" with one charger?
