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: Offers 20% higher efficiency than 12V. Provides 7.4-37 hours of power for a single device and prevents voltage sag to maintain optimal display clarity. Bluetooth 5.0 Monitoring: Easily check real-time battery data via the mobile app for convenient management. Charging Solution: Includes a 16V IP65 waterproof LiFePO4 battery charger for a full charge in 3 hours. Also supports charging via solar panels (with a controller) or generators. Built to Last: 4000+ deep cycles. Supports parallel connection (4P1S). Full protection against over-charge, discharge, current, short circuit, and high temp. Low-Temp Cut-Off: Automatically stops charging at 32℉ (0℃) and discharging at -4℉ (-20℃) to ensure safe operation in ice fishing and cold environments. Size-Enhanced for High Capacity: Engineered for tournament-long endurance. Larger than 12v fish finder batteries but offers superior energy density and runtime. Shipping Notice: Your order may be divided into multiple packages due to size/volume restrictions, resulting in sequential arrivals rather than a single shipment. LiTime 16V 30Ah LiFePO4 Lithium Battery Perfect for Fish Finders, Sonars & Marine Radars Designed specifically for demanding marine applications, this 16V 30Ah lithium battery delivers stable, long-lasting power, compatible with your Humminbird, Lowrance, Garmin, or Raymarine devices. Whether you're offshore fishing or cruising, enjoy uninterrupted operation with superior clarity and efficiency. Key Features: 1.
