High-capacity 12V lithium battery for compact deep-cycle installations

Built for deep-cycle systems requiring substantial stored energy within a reduced installation footprint, this 12.8V 325Ah LiFePO4 battery combines 4,160Wh of nominal energy with high discharge capability and integrated battery protection. The compact case is smaller than typical batteries of comparable capacity, while lithium iron phosphate chemistry provides high energy density, a flat discharge curve, fast recharge capability and low self-discharge. An integrated Battery Management System (BMS) protects against overcharge, over-discharge, temperature and short-circuit conditions, with Bluetooth connectivity providing battery monitoring through the INVICTA app.

Key Features

• 325Ah lithium capacity: Provides 325Ah at a nominal 12.8V, equating to approximately 4,160Wh of nominal energy storage for demanding deep-cycle power systems.
• Compact high-capacity construction: Uses a smaller form factor than typical batteries of comparable capacity, helping maximise energy storage where installation space is restricted.
• LiFePO4 chemistry: Lithium iron phosphate technology provides stable operation, high energy density and reduced weight compared with equivalent SLA battery technology.
• Integrated BMS protection: Built-in battery management protects against overcharge, over-discharge, temperature and short-circuit conditions.
• Bluetooth monitoring: Integrated Bluetooth connectivity enables battery information to be monitored through the INVICTA app.
• Over 2,000 cycles: Rated for more than 2,000 cycles at 100% depth of discharge (DoD), supporting frequent deep-cycle use.
• 235A continuous discharge: Supports a maximum discharge current of 235A for powering higher-demand connected loads.
• 500A pulse capability: Handles a maximum pulse discharge current of 500A for one second to accommodate short-duration current demands.
• High charge capability: Supports up to 200A maximum charge current, with a recommended charge current below 157A.
• Flat discharge curve: Maintains relatively stable voltage throughout much of the discharge cycle for efficient utilisation of available capacity.
• Low self-discharge: Helps retain stored energy during extended periods when the battery is not being actively used.
• Parallel expansion: Supports configurations of up to four batteries in parallel, while series connection is not supported.
• IEC 62619 at cell level: The battery cells are specified as meeting IEC 62619 requirements.

The combination of 325Ah capacity, 235A continuous discharge and compact construction supports high-demand deep-cycle systems where energy capacity and available installation space are key considerations.
