Why not intall a Battery Change (Off, Bat1, Both, Bat2) over switch, that
way if you run one too low for starting the other will still be fully
charged? But don't switch to the off position with the engine running.

Hi , i was wondering if there is any danger to fry the magneto of an
outboard 40hp Suzuki engine if install 2 12 volts battery in parallel .
I do use lots of 12 volt equipments on the pontoon, so i figured that 2
batteries would last longer .And last year a battery died on me in the
midle
of the lake. I just bought 2 brand new marine ones .
would that be too much strain on the magneto ?
thanks for your help !
