Since my motor is a Tohatsu 9.8 hp with electric start, I decided to connect both of my two batteries (interstate 27) together, so when I'm charging the batteries I charge both at the same time.
This way I can have double the electric reserve to run my stereo, charplotter, depht finder, and lights, and in case I run out of electric power in a day, I can always start my motor with the manual string.
My concern is if I'm damaging the bateries in some way, because I heard about sulfatation that have to be removed by a desulfatator each battery at a time.

Thak you

No, they will be just fine.

There are things on the market that will do that for you or you can use a simple battery switch and still keep one battery for starting if you want.
