Wanted to see if anyone can answer this for me. I have an FXR21 with an Ultrex, 12" lowrance on the bow, 16" lowrance at the dash. I have the 3 batteries (36 volt) for the ultrex up front and a 31 series cranking battery for everything else. If I am going to be adding the new lowrance active target will my current battery set up run the active target with no issues? Mainly on tournament day when the live well will be running and oxygenator.
