Waterproof lithium battery for high-capacity off-grid power systems

Built for large auxiliary power systems requiring substantial energy storage and high discharge capability, this lithium battery combines a rugged IP67-rated enclosure with advanced battery management and integrated monitoring. The waterproof and dust-tight construction supports installation in caravans, motorhomes, 4WDs, marine vessels and off-grid systems, while Bluetooth connectivity, CAN/485 communication and an integrated cell heater provide greater control across demanding operating conditions.

Key Features

• IP67 protection: Waterproof and dust-tight enclosure withstands temporary immersion in water up to 1 metre for 30 minutes, supporting installation in exposed environments.
• High discharge capability: Supports 300A continuous load current at 25°C and up to 1000A peak discharge for 5 seconds.
• Extended cycle life: Delivers 6,000 charge cycles at 80% depth of discharge using Grade-A prismatic cells.
• Integrated BMS: Continuously monitors individual cells and provides overcharge, over-discharge, short-circuit, thermal and high/low voltage protection.
• Built-in cell heater: Automatically controlled by the BMS to bring the cells to a suitable operating temperature for charging in freezing conditions.
• Bluetooth monitoring: Connects to the compatible mobile app for viewing voltage, current, state of charge, temperature, individual cell voltages, cycle history, alarms and diagnostics.
• CAN/485 communication: Supports real-time monitoring and control through compatible power management systems.
• Integrated SOC display: LED indicators display state of charge in 25% increments and provide visible fault alerts.
• On/off control: Built-in switch isolates the battery terminals for storage, maintenance or system shutdown.
• Reset function: Integrated reset button simplifies restarting the battery following a low-voltage shutdown.
• Expandable installation: Supports configurations of up to four batteries in series and four batteries in parallel.
• IEC 62619 certified: Cell and complete battery pack certification verifies compliance with recognised lithium battery safety requirements.
• Installation hardware included: Supplied with a battery tray and securing straps for installation.
• 5-year warranty: Covered by a five-year manufacturer warranty.

The combination of large energy storage capacity, substantial discharge capability and environmental protection supports power-intensive electrical systems in mobile, marine and off-grid applications. Integrated communication and monitoring functions provide detailed battery information for ongoing system management.
