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 

The Norsk website says this:

Quote:[font="Open Sans", Arial, sans-serif]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™. [/font]

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.

Not dissing Coho975 at all, but as President Reagon quoted many times, 'Trust, but verify.'  (Russian proverb)

Hence the link I posted that verifies the Helix is good from 10.8 volts to 20 volts... 

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 would suggest a 7ah or 10 ah 12 volt. Both are small and light and would get the job done.

Helix draws about 615 ma.  That battery weighs just over 4 lbs and will get you about 32 hours of continuous operation with your Helix ($ ???).

A 12 vdc, 10 ah lithium battery weighs about 2.5 lbs and will get you about 16 hours of continuous operation with your Helix ($35 to $40).  A 12 vdc, 7 ah is ≅ 2 lbs and ≅ 11 hrs. ($25 to $30).  Personally, I'd go with the 7 ah one.  I don't overnight ice camp/fish and would get about 2 days of operation out of it.  Decisions, decisions, decisions!  

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.
