Whether you’re trolling in calm weather or fighting the wind, this battery will back you up even with load-heavy consumption. Ideal for deep cycle applications in diverse marine environments, seasons, and temperatures for center console boats 36' feet and up. The Abyss Battery® 36V 72Ah Lithium Trolling Motor Battery gives you a long and steady draw to last even for multi-day fishing trips.

Design Features:

  • Higher qualified cylindrical cells 🔋

UL1642, IEC62619, IEC62133 listed with Cycle life more than 3000 times and excellent consistency.

    • Bluetooth® Monitoring 📲

    Monitor the battery status (charge, discharge, current, temperature, cycle life and so on) and change the data for different applications.

      • Built-in Heating ♨️
      Uniform internal heating is an important feature of our cold-weather performance batteries, as many external heating blanket options currently available cannot sense the internal temperature of the cells and may not be completely effective at heating the battery throughout. The system features proprietary technology that draws power from the charger itself, requiring no additional components. The entire process of heating and charging is completely seamless. Simply plug the battery into the regular lithium charger and the internal heating and monitoring system takes care of the rest.
      • More stable and firm internal structure ⚙️

      Cell holders protect and separate the cells to avoid any circuit short risk caused by vibration or impact or over current, and improve heat dissipation.
