Is this as simple as hooking the starting battery up to the main engine then connecting 3 separate batteries together in series to create a 36 volt bank to connect to the trolling motor alone?Do all 12 volt connections hook to the battery connected to the main engine leaving ONLY trolling motor connection to the 3 battery-36 volt bank ? Should I tap into the 36 volt bank to obtain 12 volt power for any accessories or items?What about avoiding electrolysis? Everything to a common ground block/bar? Do I just run another wire to the bus bar or how is this done safely?What about fuses? WHERE and WHAT SIZE? Switches perhaps?Am I missing something? Or is it really this simple? Im running a MinnKota Terrova 101 36v with auto pilot remote and built in transducer in the trolling motor if that matters. 25th Anniversary Edition Basscat Jaguar Silhouette with a 225 Venom, MinnKota Terrova 101 36v, New BassCat dash electronics
