Trolling motor batteries

[gb1234]

The thing I'm struggling with is that I have just a little 16' aluminum boat. It's not even a deep V. It's about as light as you can get, and not tall enough to catch much wind. I have an 80# thrust Minn Kota. Shouldn't that be more than enough power for my little boat?
It's not like I'm going out in gale force winds.
And yet spot-lock - even on the lee side of an island - is still taking it to 10 with LiFePO4s. And auto-pilot also takes it to 10 when trolling. Maybe my Minn Kota is bad?

if your auto pilot takes you to speed 10 without you setting it on 10, there's a problem with your motor. get it to a certified service center and get it fixed right.
