  • No problem
It’s a battery. 🙂. It works. Delivered fully charged and have had no issues using with my trolling motor on several occasions. No issues recharging. Satisfied so far.

We use this for a trolling motor for a small boat. Works just fine. I'd buy again

  • Battery Good, needed hardware nuts
Battery fine, arrived in great condition, charge was good, and earlier than expected. Hardware included was two screws + washers BUT NO NUTS. Ended up buying wing nuts at hardware store.

  • Works great, just charge it up
Batteries just fine. Don’t take it right out of the box and use it or you’re gonna be disappointed. You have to put it on a trickle charge until it’s 100%. And I would definitely recommend their recommendation of not taking it below 25%. This is not off the cuff advice, I’m 58 and my daddy was a mechanic so I know the drill. JTP ... show more
