Madhouse27 Posted January 13, 2006 Share Posted January 13, 2006 This topic has probably been done to death but I'll ask it anyway. I have a 24v trolling motor with two batteries, crossover etc. I've always hooked my finder up to the starting battery for the outboard. This year I will be running two finders. Do you guys just hook both finders up to the starting battery in a three battery system like mine? I'm assuming that the finders are 12 volt so I can't run them off the two battery set up I have for my trolling motor. Am I on the right track? Is there a need to add a fourth battery so I don't run down the starting battery? Thanks Quote Link to comment Share on other sites More sharing options...
ernel Posted January 13, 2006 Share Posted January 13, 2006 I am running both of my graphs off of the starting battery. They only have a draw of around 1 amp. I have a dual purpose starting/deepcycle battery and have never had any problems. I also run the livewell pumps and a Zorro fishing light system (when night fishing) off the same battery as well.

JT Bagwell Posted January 13, 2006 Share Posted January 13, 2006 Like Ernel, I run all of my electronics (bow fishfinder, GPS/Finder at console, flasher, livewells, lights, etc) off of my starting battery. The only thing on my other batteries is my 24v Minn Kota Maxxum. JT Bagwell Quote Link to comment Share on other sites More sharing options...
basser89 Posted January 14, 2006 Share Posted January 14, 2006 Just as an FYI, you can hook up both of your batteries in series for the trolling motor and if you really need to, you can connect your accessories to one of the batteries and not have any problems! Oh, my back ground, I was an electronics technician for 10 years. Quote Link to comment Share on other sites More sharing options...
