Thanks for the input. I really like Amped Outdoors lithium batteries for other applications and saw the statement on their website that discouraged lithium for cranking batteries. If going to a 5-battery setup, would it make the most sense to go with 3 lithiums for the 36V trolling motor, an AGM cranking battery for the motor, and then another lithium for all electronics? Just keep the electronics completely separate on another lithium (4 12″ graphs and Livescope)?
