    • Solid battery
Purchased for my trolling motor

    • Powered my 36lb Trolling Motor for Hours
The battery came nearly fully charged (there was some discharge from being off charger, but nothing significant). It powered my 36lb thrust trolling motor roughly 4 hours at full power - pushing a 13' fully loaded fishing kayak with 15-20mph winds, and 4' - 5' waves. I wish my adult diapers worked as good as this power cube. The battery box says that there is still over half a charge left. That's pretty impressive for the price. I'd buy it again and suggest it to a friend. ... show more

    • Great Battery for Trolling Motor
I use this battery for my trolling motor. It has been used many times and recharged without any issues.

Bought this for a 4 person blow up raft. It worked great but is very heavy.

    • Powah
This baby is chock full of power and only cost a hundred paltry American bucks, none of which made their way into the hands of the poor slaves in the third world where the minerals to manufacture it were mined....by children. Kids have sneakers to make, and minerals to mine, we use fossil fuels to do both, save the children. ... show more

    • Lots of Power
Went out for 4hrs on my canoe fishing with this for a trolling motor. Barely used any power with it and seemed to power the motor better than the other battery I had. Worth the extra wait. Can’t wait for the future fishing trips with my girls and this battery powering the trolling motor.

    • Durable
I had this battery in a Newport Vessels Trolling Motor Smart Battery Box Power Center (which I HIGHLY recommend), and despite capsizing twice in a tandem kayak designed for WAY less than its rated capacity, each time with the battery box and battery sinking to the sandy bottom of a crystal clear water river, and each time the battery box filling with water, the battery held its charge much better than expected and came within .2 of a mile of getting us 5.8 miles upstream against a 5 mph river water flow, on a kayak that had only about 1 1/2 inches of freeboard. (and yes, I know it was stupid, but we traveled a long way for the trip, and it was still fun) ... show more

    • 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
