NEVER HAVE TO JUMP START YOUR BIG ENGINE

[G3Eagle190]

In the past I've been guilty of running down my start battery by having all the lights, graphs, radio, etc drawing from the crank battery. After a long wait recently on a jump to come by (the trolling batteries were too low to crank big engine) I installed another crank battery in parallel and have never had a problem since then. Also, the alternator keeps both crank batteries fully charged. I always check them before going back out. FYI

I replaced my cranking battery with a group 27 trolling motor battery two years ago and have never not been able to crank the big motor even while fishing at night will all the lights, including black lights on.
