12V 300Ah – Group 8D – Cranking & Deep Cycle Lithium Battery (Dual Purpose)

The 12V 300Ah Group 8D Cranking & Deep Cycle Lithium Battery offers an ideal solution for both cranking and deep-cycle applications. With LiFePO4 chemistry, this dual-purpose battery combines high discharge capabilities with deep cycle performance. Perfect for marine, RV, off-grid, and solar power systems, it is built to endure extreme conditions, offering 6000+ cycles, internal heating, Bluetooth connectivity, and seamless Victron communications for advanced power management.

Key Features:

• 12V 300Ah Group 8D Dual-Purpose LiFePO4 (3.84kWh): The ultimate marine and RV drop-in upgrade. Combines massive deep-cycle energy storage with heavy-duty engine cranking power, all inside a standard Group 8D physical footprint.
• True Cranking Power & High Output: Delivers an astonishing 1,000A peak discharge (for 5 seconds) and 800A (for 10 seconds) to reliably start marine engines, alongside a massive 300A maximum continuous charge/discharge rate to effortlessly run heavy house loads and 3,000W+ inverters.
• Seamless Victron CANBUS Integration: Features native CAN communications for the entire string of batteries, allowing for plug-and-play integration, closed-loop charging, and advanced monitoring directly within the Victron ecosystem.
• IP67 Waterproof & Sub-Zero Heated: Encased in a fully sealed, submersible housing (up to 1 meter deep) with internal self-heating technology that ensures safe, reliable charging in freezing, sub-zero conditions.
• Smart Bluetooth with OTA Updates: Monitor real-time capacity, voltage, and battery health via the free Epoch iOS and Android apps, featuring built-in support for Over-The-Air (OTA) firmware updates to keep your battery’s software optimized for years to come.
• Massive Scalability (Series & Parallel): Highly versatile architecture allows you to wire up to 4 batteries in series (for up to 48V systems) and up to 16 batteries in parallel to build an ultra-high-capacity energy bank.
• Expandable Tech Ecosystem: Built to adapt, with built-in readiness for upcoming Epoch accessories including an external touch-screen battery gauge and an advanced communications box for broader inverter and NMEA2k compatibility.
• Advanced Smart BMS Protection: The integrated Battery Management System automatically guards against over-current, short circuits, and extreme high/low temperatures to protect your investment.
• 6,000+ Cycle Life & 11-Year Warranty: Exceptional, maintenance-free longevity boasting over 6,000 cycles (significantly higher than standard lithium), backed by an industry-leading 11-year manufacturer warranty.
