Pro-Grade Imaging: 16V voltage delivers clearer, brighter charts and superior side/down/forward imaging for your fish finder, unlocking its full potential. Device Compatibility: Optimized for Humminbird, Garmin, and Lowrance fish finders, sonar, and radar. Note: For Lowrance units, a 16.4V voltage regulator (sold separately) is required during charging to ensure normal use. Stable Clean Power: A dedicated 16V system isolates against interference, providing more stable and consistent power than 12V systems for sensitive sonar and marine electronics. Extended Runtime: Power up to 5 fish finder units simultaneously for 10-16 hours and prevents voltage sag to maintain optimal display clarity. Offers up to 25% longer runtime than traditional 12V batteries. Bluetooth 5.0 Monitoring: Easily check real-time battery data via the mobile app for convenient management. LiTime 16V 100Ah LiFePO4 Fish Finder Battery Engineered for serious anglers, this 16V lithium battery delivers superior power for marine electronics while withstanding harsh fishing conditions. Its stable voltage output enhances sonar clarity, while smart features like Bluetooth monitoring and self-heating ensure reliable performance in any environment. Key Advantages: 16V optimized voltage maintains consistent power for clearer fish finder imaging vs 12V batteries 100Ah capacity runs 5 units for 10-16hrs (25% longer than 12V) with 4000+ cycle lifespan Bluetooth 5.0 monitoring tracks SOC, health and charging status via smartphone Arctic-ready with -20°C protection + 110W self-heating for ice fishing Marine-grade IP65 waterproof casing withstands splashes and corrosion Parallel-ready (4P1S) for capacity expansion Group 27/31 compatible direct replacement with physical power switch Perfect for: Compatible with Humminbird/Garmin/Lowrance fish finders (Note: Lowrance devices may require a 16.4V voltage regulator when charging as charging voltage reaches 18.25V) Ice fishing and cold climate expeditions Multi-day fishing trips Commercial fishing operations
