I got a ethernet hub and ran the ethernet cable for the ultrex quest and both my helix units to it. It immediately popped up for the trolling motor battery set up, which is what I was after. Now my problem. It asks for battery capacity type, either amp hours, 20 hr rate, or a 2 discharge rate. I have Deka deep cycles DC31DT. The label says MCA@32 degrees 800, CCA at 0 degrees 650, and MIN @23amps 225. My label doesn't jive with the info the humminbird asks. Can anyone clear this up for me. Thanks, Joe
