    15AH Lithium-Ion Battery

    dave.koonce (verified purchase)

    This battery has a lot of juice !! Long lasting power when used with my Helix Ice 7. My first outing was on Mille Lacs and I had about 16 hours of use in two days and it still had 3 out of 4 lights left on the power indicator. Having the two USB ports allowed me to charge up my phone too… I can see multiple uses for having those ports for sure !! I ordered this battery on-line and it was shipped out the next day via Spee-Dee Delivery … Fast Turn Around !!

    Awesome

    Jordan (verified purchase)

    I had this out for a day and a half trip on the lake and ran my Helix 7 the entire time. I also ran lights off the usb port for multiple hours. This still had a charge when I left.

    I love this battery. It was shipped super fast! I used it in my Vexilar for two days and its still shows 4 out of 4 for charge left in the battery. I’m amazed at weight difference compared to my regular Vexilar battery.

  10. Awesome!

    Mark (verified purchase)

    This battery is unbelievable. A fraction of the weight of my old wet cell style battery and the run time is amazing. Love the two usb ports and the power indicator. I wish I would have purchased this battery right from the get go and not bought the cheap one’s

  12. Could have given it a 5 star

    JOHN (verified purchase)

    I am impressed with the light weight in the standard size for ice fishing locators. After using it this winter I am still confused how the voltage indicator on my Lowrance unit drops .1 volt per hour and is down to 11.3 volts after 7 hours but the indicator on the Norsk battery still shows 3 of 4 lights on. I was told by Norsk that my unit was not calibrated for a Lithium battery however Lowrance disagrees. This is the only reason I did not rate 5 stars.

  13. My Favorite Battery By Far!

    mannyt (verified purchase)

    Can’t get enough of these batteries – I actually bought 2. One for the house and one for fishing! The USB’s are a huge added bonus – my wife uses one to charge her phone next to the couch.

    This is by far the best battery on the market for running our ecallers. Long run time and so light makes for easy in and out of muddy fields in the spring. We charge once every three days now instead of every night. 👌👌👌

  15. Power For Days

    Kyle K

    I run a Marcum underwater camera year round to find weed lines and submerged structure. With this 15AH battery my camera is powered for DAYS without needing a recharge. Highly recommend.
