IP67 lithium battery for compact marine, 4WD and off-grid power systems

The Enerdrive B-TEC ULTRA 12 V 100 Ah LiFePO4 Battery combines compact energy storage with an IP67-rated enclosure for marine, caravan, 4WD, trailer and off-grid installations. An integrated Battery Management System (BMS) monitors and protects the battery against electrical and temperature-related conditions, while a built-in cell heater supports charging in cold environments. Bluetooth monitoring and CAN/485 communication provide access to battery operating data, with onboard controls and an integrated display simplifying day-to-day battery management.

Key Features

  • IP67-rated enclosure: Dust-tight construction with protection against water immersion for exposed and external installations.
  • Integrated BMS: Provides overcharge, over-discharge, short-circuit, thermal and high/low voltage protection.
  • Built-in cell heater: Automatically controlled by the BMS to bring the battery to a suitable operating temperature for charging in cold conditions.
  • Bluetooth monitoring: Compatible with the Enerdrive B-TEC App for monitoring battery status, individual cell voltages, temperature, cycle history, alarms and diagnostics.
  • CAN/485 communication: Supports real-time monitoring and control through compatible power system equipment.
  • Integrated SOC display: LED indicators show remaining charge in increments and provide fault indication directly on the battery.
  • Built-in controls: On/off functionality isolates the battery terminals, while the reset button assists with restarting a discharged battery.
  • Expandable battery banks: Supports series and parallel configurations for larger or higher-voltage energy storage systems.
  • IEC 62619 certified: Certified at both cell and completed battery pack level for lithium battery safety.
  • Installation hardware included: Supplied with a battery tray and straps for secure mounting.
  • Long service life: Grade-A prismatic cells support extended cycling for frequently used auxiliary and off-grid power systems.
  • 5-year warranty: Covered by the manufacturer's warranty.

Its compact dimensions make the battery particularly suitable where installation space is limited while retaining the monitoring, environmental protection and system expansion capabilities of the B-TEC ULTRA range.
