Not enough power to get me through the day of fishing.
Rating: 3 out of 5 stars
I purchased this battery to power my new NV #55 trolling motor. I was told by customer service that this battery would have more than enough power to power my 12 ft aluminum Jon boat. During my first trip with this battery I found that it began to fail/run low on amperage after only a couple hours. It did complete the journey I was making, but the trolling motor was definitely going slower at the end. When I first considered ordering one of these, I was worried that such a small light weight battery would have enough power to get me through a day of fishing. I was right.

This battery is worth it

Great Battery, well made and great run time with my 62# motor
Rating: 5 out of 5 stars
Great Battery and has long run time. I like that it is a little smaller than my previous group 27 and has the same run time.

Lead acid battery
Rating: 5 out of 5 stars
If you want to go the lead acid battery route, Newport has got you covered. These batteries are much lighter than other lead acid batteries out there. You’ll be happy you went with this over others.

Best idea for your battery
Rating: 5 out of 5 stars
I like the product because it is easy to use and it keeps my battery away from the elements. Also, there is a USB port and a 12 volt (cigarette type) port. Best of all - it has a gauge that tells you how much battery life is left. Imagine being out in the middle of a large lake with a battery failure with only an electric motor!

Awesome customer service.
Rating: 5 out of 5 stars
Approx three months ago I made my first purchase from Newport buying a trolling motor & battery for my fishing kayak. I couldn’t be anymore pleased with the products. In fact, I purchased a second motor & battery for my son’s kayak which is a different model so I had questions. The Newport employee that I spoke with took the time to explain the differences in the products and what would work best with my kayak. Scott I
