    • Durable and well made
Heavy duty and well made. I bought this and charged it up and it charged perfectly. On the very first trip out with it to test it with my trolling motor, it took a tumble out of my truck bed onto the road at about 20 MPH. I quickly jumped out and ran back and grabbed it and found that a corner got a little beat up but otherwise, it was completely fine. Since then, there has been zero swelling, charging issues or output issues. This is heavy duty and well protected if it can take a tumble onto asphalt and still be just fine. Save the money you'd spend on some name brand battery and go ahead and grab one of these. ... show more

    • Great battery that lasts
I purchased this battery to power my small 18’ rowboat I use in the estuaries and sounds where I live. I was able to tootle around for 6 hours and still had more than half battery remaining. It’s a great value for the money. It is lightweight and small to carry back and forth from the garage to the car and boat and back. It provided sufficient power for my small motor. ... show more

    • 🌟🌟🌟🌟🌟 Surprisingly Lightweight Yet Powerful A Reliable Battery for My Trolling Motor
As someone who uses a trolling motor regularly for fishing trips, I’ve gone through my fair share of marine batteries. This Newport 12V 50Ah Deep Cycle battery impressed me right out of the box. First, it’s much lighter than traditional AGM or lead-acid batteries I’ve used before easy enough to carry with one hand, which makes loading and unloading from my boat or vehicle much less of a hassle. Performance-wise, this battery delivers steady, consistent power. I ran it on a Newport 55lb thrust trolling motor and got a solid 4+ hours on moderate speeds with some bursts at higher throttle. Voltage remained stable the whole time, which means the battery didn’t sag under load like some cheaper options tend to do. Build quality also seems solid tight casing, clean terminals, and no noticeable heat build-up during extended use. It’s sealed and maintenance-free, which is a must for anyone who doesn’t want to deal with checking water levels or corrosion issues. One small point to note: there’s no built-in charge level indicator. I solved this by adding an external voltage meter, but it’s something to keep in mind if you like having that convenience. Overall, this battery strikes a great balance between weight, capacity, and price. It’s not the cheapest out there, but the portability and reliability make it a solid investment for serious boaters, kayak anglers, or even off-grid solar setups. Highly recommended. ... show more

    • Compact
Use in my kayak to power Newport trolling motor. Like the smaller size and weight ( 30 lb) vs standard marine battery (50 lb). Of course amp hrs (50) vs standard marine battery amp hrs. (85) is less. Here is my complaints. The carrying handle is a thin rope. Although it works I believe it will not last long. Just one scrape on the thin rope when carrying will I will be dropping 30 lbs on the ground or foot! The second issue is the bolt used on negative and positive terminals. As I have to install and connect trolling motor and battery after launching the kayak I have to remove bolts for ring end connectors on trolling motor and bolts can drop. Ok I could have extras and I will but it would be so much better to have wing nuts that you tighten by hand. Also as I carry two batteries on kayak, making a change from one battery to the other entails the same issue of dropped bolts when on the water. ... show more

    • Good marine battery
Held up using a 50 lb. Thrust trolling motor all day. About 1/2 the weight of other batteries.

    • No fuss
Hooked it up to the trolley motor, worked great. Have to check back in when I finally take it out to see how long it lasts, and if it recharges.
