I'm thinking about adding another battery dedicated just to my electronics. That way, no matter how long I fish, I wont have to worry about pulling down my starting battery. I don't really want to run them off my trolling batteries since it is a 36 volt system. Don't want he extra load on one of the trolling batteries. I don't think I have enough room in the back for another battery so I'm thinking about adding one to the storage compartment in front to the drivers console with a dedicated fuse block just for the electronics. What are your thoughts pro or con?
