I've got a 65lb Minn Kota upfront running off of 2, 12V batteries in parallel (Although I think a Terrova is in my near future) Humminbird 747c upfront as well running off one of the trolling batteries.. 2 bank charger for both of those as well.. Rear battery runs all the electronics on the console, big motor, dual Scotty 1106s and will run the Yamaha High Thrust T8 kicker once it's installed. I've got an extra spot in the rear for another battery that I might install, so 4 total in the boat, lol.
