Digital sonar and live imaging transducers operate most-efficiently when powered by a 14.8V Norsk Lithium battery that is designed to provide clean power at a higher voltage than what is possible with a lead acid (12.6V) or LiFePO4 (13.8V) battery. In addition to clearer images, you'll also see a 15%-20% longer runtime compared to a LiFePO4 battery of the same capacity which means you can fish longer, with less weight, and maximize the performance of your Mega Live, Live Scope or Lowrance Active Target 1 / 2. If you're looking to build a lightweight live imaging bundle the Norsk Lithium 14.8V 15Ah battery is a compact powerhouse that shares the same dimensions as a standard flasher battery (5.94 X 2.56 X 3.66 inches), yet it weighs in at featherweight 2.7 Lbs!
