Norsk 11.1v, 15AH Lithium-Ion Battery with 2A Charger Kit

Norsk 11.1v 15AH Lithium-Ion Battery with Charger - Designed to provide 15+ hours of runtime on the most common sonar units with screens up to 7in. This little powerhouse is the same dimensions as a standard flasher battery (5.94 X 2.56 X 3.66 In) but weighs only 2.6 lbs. The Norsk 15Ah lithium ion battery will run for more than 1,000 charge cycles and comes with a Manufacturer's two-year limited warranty.

Battery Monitoring System (BMS) - The Norsk 15Ah Lithium Battery comes equipped with a BMS system that makes it fool-proofed and worry-free. The BMS won’t allow the battery to receive a charge until its internal temperature has warmed to a safe 32F. Once it’s safe, the BMS will allow the lithium battery to recharge. Norsk's advanced BMS technology prevents your Norsk 15Ah lithium ion battery from overcharging. Even if you completely hook up your lithium-ion battery charger to the wrong terminals, the BMS will prevent it from receiving any charge.The BMS ensures cell balancing during discharge and charge cycles, low and high voltage cutoff, short circuit protection, and high-temperature protection. 

Dual USB Ports - The Norsk 15Ah Lithium battery’s patten-pending, dual USB ports allow you to enjoy the outdoors in the 21st century. These allow you to power your cell phone, go-pro, or nearly any USB-compatible device while your lithium battery powers your fish finder.

Battery Power Indicatior - The Norsk 15Ah lithium battery has an enormous runtime. But it will run out of juice eventually. With the LED power indicator, you can know when. Just press the button, and the LED Power indicator will let you know how much power your lithium battery has left. 

The right Lithium chemistry for the right application - Lithium-ion chemistry provides exceptional power while also offering a significant weight advantage. Lithium-ion batteries have one of the highest energy densities of any battery technology currently available. The Norsk 15Ah lithium battery is remarkably potent – and so light – you’ll barely notice it when you charge across the ice to the best spot for feeding time! 

The standard Lithium Ion battery for Humminbird - The Norsk 15Ah lithium ion battery is the standard power source for Humminbird’s Ice Helix 7 CHIRP GPS G4 All Season.
