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

The Epoch Pro Series 12V 300Ah Group 8D Dual Purpose Lithium Battery is engineered for users who need both exceptional engine-starting power and long-lasting deep-cycle energy storage in a single battery. Combining advanced LiFePO4 technology, integrated Bluetooth monitoring, internal heating, Victron CANBus communications, and an intelligent Battery Management System (BMS), this battery delivers unmatched performance for marine, RV, off-grid, emergency backup, and commercial power applications. Designed as a true dual-purpose battery, it eliminates the need for separate starting and house batteries while providing the reliability and longevity that modern power systems demand.

True Dual-Purpose Cranking and Deep Cycle Performance

Unlike traditional batteries that are optimized for either starting or deep-cycle use, the Epoch Pro Series 300Ah is built to excel at both. Delivering up to 1,000A peak cranking power for 5 seconds and 800A for 10 seconds, it provides the starting power required for large outboards, marine engines, and other high-demand equipment. At the same time, its massive 300Ah capacity and 3.84kWh of energy storage provide extended runtime for electronics, inverters, trolling motors, refrigeration, communications equipment, and onboard power systems.

Advanced Bluetooth Monitoring and Victron Integration

Built-in Bluetooth connectivity enables real-time battery monitoring through the Epoch mobile app for iOS and Android devices. Users can instantly view:

  • State of Charge (SOC)
  • Voltage
  • Current
  • Temperature
  • Battery health and diagnostics
  • Charging and discharge performance

For advanced energy storage systems, native Victron CANBus communication allows seamless integration with Victron GX devices and the broader Victron ecosystem, making this battery ideal for professional marine, RV, and off-grid installations.

Internal Heating for Cold Weather Charging

The integrated self-heating system allows safe charging in temperatures as low as -4°F (-20°C), automatically protecting the battery during cold-weather operation. This feature makes the battery ideal for year-round marine applications, remote installations, emergency response equipment, and outdoor power systems where freezing temperatures are common.

Rugged IP67 Waterproof Construction

Designed for harsh environments, the battery features an IP67-rated enclosure that provides protection against dust, water intrusion, vibration, and challenging operating conditions. Whether installed in a boat, RV, utility vehicle, mobile workstation, or off-grid energy system, the Pro Series battery is built for dependable operation in demanding environments.

Intelligent Battery Protection

The advanced Smart BMS continuously monitors battery performance and provides protection against:

  • Overcharge
  • Over-discharge
  • Overcurrent
  • Short circuits
  • High-temperature conditions
  • Low-temperature charging conditions

These safeguards help maximize battery lifespan while ensuring safe and reliable operation.

Expandable for Large Energy Systems

The Epoch Pro Series 300Ah is designed for scalable energy storage installations and supports:

  • Up to 4 batteries in series (48V systems)
  • Up to 16 batteries in parallel
  • Up to 61.4kWh of total system storage capacity

This flexibility makes it suitable for large marine electrical systems, commercial backup power, off-grid solar arrays, telecommunications infrastructure, and enterprise energy storage projects.

Long Service Life and Reduced Operating Costs

Built with premium Lithium Iron Phosphate cells, the battery delivers over 6,000 charge cycles and maintenance-free operation. Compared to traditional AGM and lead-acid batteries, it offers significantly longer service life, greater usable capacity, faster charging, and lower total cost of ownership over the life of the system.
