High-capacity IP67 lithium battery for large marine and off-grid power systems

The Enerdrive B-TEC ULTRA 12 V 460 Ah LiFePO4 Battery delivers substantial energy storage for large marine, caravan, 4WD and off-grid electrical systems. Its IP67-rated enclosure is dust-tight and protected against water immersion, supporting exposed installations where environmental protection is essential. An integrated Battery Management System (BMS) manages cell protection and charging conditions, while the built-in cell heater supports charging in cold environments. Bluetooth monitoring, CAN/485 communication, an integrated state-of-charge display and onboard controls provide comprehensive battery monitoring and management.

Key Features

  • IP67-rated construction: Suitable for external and exposed installations where protection from dust and water ingress is required.
  • High-current capability: Supports demanding equipment including large inverters, induction cooktops, compressors, fridges and other substantial electrical loads.
  • Integrated BMS: Provides overcharge, over-discharge, short-circuit, thermal and high/low voltage protection.
  • Built-in cell heater: Automatically controlled by the BMS to support charging in cold operating conditions.
  • Bluetooth monitoring: Connects to the Enerdrive B-TEC App to monitor battery status, individual cell voltages, temperature, cycle history, alarms and diagnostics.
  • CAN/485 communication: Enables real-time monitoring and control with compatible system equipment.
  • Integrated SOC display: LED indicators provide an immediate indication of remaining battery charge and fault conditions.
  • Built-in controls: On/off functionality isolates the battery terminals, while the reset function assists with restarting a discharged battery.
  • Dual positive and negative terminals: Provides greater flexibility when connecting high-current loads and configuring larger battery systems.
  • Expandable battery banks: Supports series and parallel configurations for larger capacity or higher-voltage installations.
  • IEC 62619 certification: Certified at both cell and completed battery pack level for lithium battery safety.
  • Long cycle life: Grade-A prismatic cells support extended operation in frequently cycled applications.
  • Mounting hardware included: Supplied with a battery tray and straps for secure installation.
  • 5-year warranty: Backed by the manufacturer's warranty.

Its large storage capacity and substantial continuous discharge capability make it suited to power systems running multiple high-demand appliances or requiring extended operation away from mains power.
