Trolling Motor Battery

[MBM1969]

I am putting a 30lb thrust trolling motor on my 8ft Pontoon boat in the next couple weeks. I need to decide what battery to use. Weight is a bit of a concern, I'm 6'6' and 270lbs so with trolling motor and battery I am worried I am pushing the limit of my kickboat. I am leaning toward a group 24 deep cycle instead of the bigger group sizes. I have heard people talk about using wheel chair batteries but I am not sure if they will hold a long enough charge. I don't plan on trolling all day just using the motor to get back and forth to fishing spots and using my flippers for most of my actual fishing.

Any suggestions?
