The Abyss Battery® 12V 300AH Off-Grid™ Marine Lithium Battery is a high capacity Dual-purpose performance Lithium-ion battery with a Group 8D footprint. This battery is ideal for off-grid living, energy storage applications, and starting large outboard or diesel motors. 

The module's inherent safety, extended cell life, and zero maintenance offers end users a more reliable battery alternative by performing with more than twice the run-time and <70% of the weight of similarly sized AGM batteries. 

Our integrated Battery Management System is designed to operate seamlessly with any application and manages all of the modules system parameters in real-time.

  • Higher qualified cylindrical cells 🔋

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

    • Bluetooth® 📲

    Can 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 can well protect and separate the cells to avoid any circuit short risk caused by vibration or impact or over current, and improve dissipation.
