High-capacity IP67 lithium battery for demanding mobile and off-grid power systems

The Enerdrive B-TEC ULTRA 12 V 300 Ah LiFePO4 Battery delivers substantial energy storage and high-current capability for marine, caravan, 4WD, trailer and off-grid power systems. Its IP67-rated enclosure supports exposed installations, while the integrated Battery Management System (BMS) provides protection against overcharge, over-discharge, short circuit, thermal conditions and high or low voltage. A built-in cell heater supports charging in cold environments, while Bluetooth monitoring, CAN/485 communication, an onboard state-of-charge display and integrated controls provide comprehensive battery monitoring and management.

Key Features

• IP67-rated construction: Dust-tight and protected against water immersion for demanding marine, vehicle and external installations.
• High-current capability: Supports demanding electrical loads including large inverters, induction cooktops, compressors, fridges and other high-draw equipment.
• Integrated BMS: Continuously monitors individual cells and provides electrical and thermal protection.
• Built-in cell heater: Automatically controlled by the BMS to support charging in cold operating conditions.
• Bluetooth monitoring: Compatible with the Enerdrive B-TEC App for viewing battery voltage, current, state of charge, temperature, individual cell voltages, cycle history, alarms and diagnostics.
• CAN/485 communication: Supports real-time battery monitoring and control with compatible equipment.
• Integrated SOC display: LED indicators provide an at-a-glance view of remaining battery charge and fault conditions.
• Built-in controls: On/off functionality allows the battery terminals to be isolated, while the reset button assists with restarting a discharged battery.
• Dual terminals: Two positive and two negative terminals provide additional flexibility for wiring, parallel connections and load distribution.
• Expandable configuration: Supports series and parallel connection for building larger battery banks and higher-voltage systems.
• 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 service in frequently cycled applications.
• Secure mounting: Battery tray and straps are included for installation.
• 5-year warranty: Backed by the manufacturer's warranty.

Its high-current capability and dual-terminal configuration make it particularly suited to larger auxiliary and off-grid electrical systems where multiple high-demand loads need to be supported from a single battery bank.
