A few months ago I bought a power pole charge, I’ve got to say its the real deal. I have a 4 battery setup 1 agm and 3 lithiums. I’ve been fishing several times and have never left the lake low batteries yet. I haven’t fished any all day tournaments this year or ran the livewells for hours on end but I’m amazed at how well it works. I did fish three days straight without plugging in my boat and at the end of every day all my batteries were in the green. Definitely recommend the powerpole charge.
