Mighty Max Battery 12V 8Ah SLA Battery Replaces Lowrance Elite-3x Fish Finder

Wanted a portable battery for use in my 12' kayak. Connected to fish finder. Works great. Not too heavy.

This powered up my fish finder and doing well so far. Great product.

Fish finder work and the battery did its job.

Good value. I use this as a back up for my cpap machine when the power is out. On a full charge using my Cpap with the humidifier and heater, I get a solid 8 hours of operation. If I'm camping I lug it along and don't use the heater/humidifier. I get approx. 14 hours of operation.Charges well. It's the lightest solution I could come up with that is inexpensive. Cut the weight in half and it would be 5-star!

👍👍

Using battery to run my Garmin fish finder on kiyak. Does a good job, happy with it.

I replaced my older kayak fish finder battery with this one and I’ve been using it for a few months now. The charge lasts at least a 12 hour day of fishing running a Lowrance Elite 4x. I stow it in the Hobie mount in the stern hatch. It’s heavier than the lithium battery solutions out there, but it’s also cheaper if you’re only running a fish finder without side scan or charging other devices.

Battery works good, but connectors are weak (to compare: my other brand battery I also use has no issues).First broke off after about 5-7 uses, second (replacement) survived longer, but also broke. I guess if you have it permanently attached to extension cable it should last longer. Company was quick with warranty replacement, but charged for shipping.
