The Next Evolution in Battery Energy Storage

The B-TEC ULTRA 12V 300Ah Lithium Battery delivers maximum power with uncompromising safety. Built for marine, 4WD, and off-grid applications, it combines serious performance with IP67 protection from the elements — giving you the confidence to explore further and push harder, no matter what conditions you face.

Built to Withstand the Elements

Rated IP67, the B-TEC ULTRA is fully protected against dust ingress and can withstand submersion in water up to 1 metre for 30 minutes. This makes it suitable for external mounting on boats, 4WDs, caravans, and trailers where exposure to moisture and dust is unavoidable.

High Performance Power

With 300A continuous discharge and a peak discharge of 1000A for 5 seconds, the B-TEC ULTRA is built to handle demanding loads — inverters, winches, fridges, induction cooktops, and air compressors. Rated for over 6,000 charge cycles at 80% depth of discharge using premium Grade-A prismatic cells, it's engineered for long-term reliability.

Safety Certified to IEC62619

The B-TEC ULTRA is IEC62619 certified at the cell level, one of the highest global safety standards for lithium-ion batteries. Certification involves rigorous testing across electrical, mechanical, and environmental stress conditions, including short circuit, impact, crush, overcharge, and thermal stability testing.

Smart Monitoring & Control

Monitor your battery in real time via Bluetooth using the Enerdrive B-TEC App (iOS & Android), tracking voltage, current, state of charge, temperature, cycle history, and system alerts. CAN/485 communication also enables integration with compatible monitoring and control systems.

Practical, Field-Ready Features

  • Built-in display shows state of charge in 25% increments
  • On/off button isolates the terminals instantly for safety or storage
  • Built-in reset button for quick recovery from a flat battery
  • Battery tray and strap included for fast, secure installation
