I have a brand new 24v Minn Kota with 70lb thrust. I also have 2 year old interstate batteries. I want to run 1.4 ot 1.5 with the boat. I need to run the motor at 6 or 7 on the pad to achieve the speed.
How long should the batteries hold power?
I am only getting 1 hour out of them before I have to slide the power on the pad up to 10. I took the batteries back and the told me they were good.
Is your boat really heavy? Maybe more thrust on a trolling motor is needed? Maybe a second opinion on the batteries? Are they old batteries...I end up replacing mine every few years and use the old one for other things. Good luck...
