Fish finder battery

The Norsk website says this:

The 14.8V 20Ah Lithium-Ion Battery is purpose-built for live imaging and forward-facing sonar systems, making it the perfect choice for users of Humminbird MEGA Live Imaging™, Garmin Livescope™, and Lowrance ActiveTarget™.

I recommend you call Humminbird and ask them if the Helix series is compatible with a 14.8 vdc battery

It will work great, Helix units can handle up to 20 VDC. Those are good batteries, I run one on my ice unit as well.

For what its worth, I use a similar (different brand) lithium with my Helix 7 for ice fishing.  No problems with it.  A few more amps and a lot less weight to carry.

I personally have a 7ah lead battery and it powers my ice finder for way longer than I can fishing in one day. I charge mine after a day’s worth of fishing with a little charger made for it. Take about 3-4 hrs of charging. Less (weight and space) is “more” to me.

Does anyone know if I would be able to use this for my humminbird helix 5 ice fish finder have a couple of batteries for it but want to cut down on weight
