## Customer Reviews

### ⭐⭐⭐⭐⭐ Good to power a fishfinder .
*by B***  on October 26, 2020*

After my first 10 Ah battery stop working for no obwious reason , I noticed a new model with bigger capacity.I decided to take a chance and buy a 15Ah version.So far is working well and after a few hours on the water , battery is still almost fully changed.It is important to know how much power is needed, so current drawn from a battery will not exceed allowable amount.I do like a small size and weight of this product, and relative water resistance from splashing is helpful.So far I am happy with this battery and hope it will last.

### ⭐⭐⭐⭐⭐ Very lightweight! Great option for kayak anglers!
*by C***S on August 21, 2020*

When I was looking for a battery to power a fish finder for my kayak, I was pretty much decided on the Nocqua power pro kit, because that seems to be the go-to for kayak anglers on all the forums I follow. Then, I saw this little guy. I've always had good experiences with Wilderness Systems products, and was excited to see that they had a comparable offering. This one even comes with two 5v usb charging ports. I was sold!So far, this battery seems to be a great. It's very lightweight, which is great for kayak anglers. I have a sit-on-top kayak that doesn't have a lot of hull access, an I was not crazy about mounting the battery in the hull. I was pleased find that the light weight of this battery allows me to simply zip-tie the battery to my yakattack mount for my striker 4. This allows me to have the fish finder and power source in a self-contained unit that can just bolt onto a gear track! This mounting option also allows me access to the available usb charging ports. I would have had to run additional wires to make that happen, had I chosen to mount the battery in the hull.I only made one hole in the kayak, and that's for the transducer cable. Super clean and easy to manage. That's exactly what I was looking for. I've done some basic testing of the battery, and it is able to run the striker 4 for 8+ hours continuously (I have yet to fully drain the battery), on the brightest setting in simulation mode. I'll update this review with any additional findings out on the water. I plan on taking it out this weekend.

### ⭐⭐⭐⭐ My device is not pretty, but it works
*by M***. on July 27, 2020*

Not pretty, but seems functional. Why didn’t quality control fix this? Seems like a glue issue (I hope)
