I use a Deep cycle battery for everything on the boat except trolling motor (starting, depth finder, bilge, radio, etc)
And i use another Deep cycle battery for the trolling motor.
My question is, is this how I should have it setup? My newest battery is the one i use for starting, etc. and it just died on me. My old battery that is on the trolling motor has been going strong for 8 years.
Thanks for any input
