What kind of battery are you guys using?
I have been using the AGM type but now learning that these should not be drawn down past 50% I usually run them down to 30% or sometimes ZERO

I did recently have to dump one of my smaller ones. Maybe that was the reason.
I primarily use a 7Ah battery for my Lowrance Hook 5 and a larger 14Ah for my bait tank pump. I hear the Lithium Ion Phosphate batteries are the best.
LiFePO4
Thanks!
