I’m up grading from a 24v Fortrex to a 36 Fortrex. The boat is a TR20x seems to be plenty of room but just not sure. This will be my first 36v setup I installed the extra battery tray yesterday. I have 2 then the oil tank then 2 trays on other side. I assume this is best way for even weight distribution. I’m assuming they make long jumper cable to connect that third battery on far side of oil tank. But not sure the trolling motor cable will reach that far?
