What It Does on the Water

Live sonar systems draw consistent power demands that standard marine batteries are not optimized for. The 14.8V 15Ah lithium-ion NMC chemistry delivers stable voltage output throughout the discharge cycle, keeping your sonar performing at full capacity from the first cast to the last. At approximately 4.2 lbs, it fits cleanly into most live sonar setups without adding unnecessary weight to the bow.

The LED state-of-charge indicator gives you a quick read on remaining power. Deep Sleep mode disconnects power from the terminals via the Norsk Guardian app or the one-touch Power Management button to eliminate phantom draw during storage. BMS protection covers overcharge, over-discharge, overcurrent, short circuit, and high and low temp shutoff. Rated for 2,000+ charge cycles.
