My cranking battery is dieing on me while fishing. It is a interstate with 800cca. I am running 997,797,and aireator now but going to be running a bilge pump for my shad tank and lights for night fishing. I want to know which would be better,wiring another cranking battery with the existing battery or getting a deep cycle for just electronics? I have had cranking battery tested and it is good. Boat is a ranger r71 with merc125.
I got the boat in febuary.
Get a bigger cranking battery....get a group 31 combination deep cycle and cranking.
I have spent most my life fishing........the rest I wasted.
