I picked up a nice Motorguide Brute750 12/24v bow mount yesterday. Its a 12/24v.
Question 1: If I just use it on 12v setting with one battery will it run 1/2 power, or full power for about half as long?

Question 2: When/if id do get a 2nd deep cycle battery, can I still tap off just one to run the fish finder. Will the connection from + to - affect the 12v output of one of the batteries.

Pretty elementary stuff, just haven't dealt with a 24v setup before. :redface:
