I am seeking a do everything 12v lithium for my 17' Maverick flats boat with a Yamaha 90 2 stroke. The style of fishing is sight fishing so unless there is heavy wind the TM is running 8 to 9 hours at slow to moderate speed for stealth.
I have a power pole that gets used a few dozen times a day on average and a basic Simrad NSS7 that stays on all day for navigation. I currently have group 31 AGM for the 12v Minn Kota Terrova
and a smaller AGM for starting, power pole and navigation gps. Believe it or not shedding 70lbs on this boat is a pretty big deal. I am wondering if there is a single lithium battery that could handle this load and still start the motor at the end of the day? For those using a lithium battery for starting, what is the lowest state of charge that will still start a outboard?
