Epoch 12V 314Ah Marine Lithium Battery – Eco Series LiFePO4 Deep Cycle | Long Life, High Capacity
Epoch 12V 314Ah LiFePO4 deep cycle battery – 8000+ cycles, advanced BMS, IP54 weatherproof design, safe, efficient, and maintenance-free.
PRE-ORDER JULY 1st

The Epoch 12V 314Ah Eco Series LiFePO4 Battery is engineered to deliver exceptional power, safety, and longevity for marine, RV, and off-grid energy systems. With an impressive 8,000+ cycle life, this high-capacity lithium battery offers a sustainable, maintenance-free energy solution built to outperform traditional lead-acid batteries in every way.
Constructed with LiFePO4 (Lithium Iron Phosphate) chemistry, it provides reliable and efficient deep-cycle performance while remaining lightweight and eco-friendly. The Advanced Smart Battery Management System (BMS) includes over 20 integrated safety features, protecting against overcharge, deep discharge, overcurrent, short circuits, and temperature extremes.
Its low-temperature charge protection ensures the battery automatically prevents charging in freezing conditions, safeguarding long-term performance. The IP54 weatherproof design makes it ideal for harsh marine environments, and with series and parallel capability (up to 48V or 64.3 kWh), it’s suitable for large-scale energy systems.
Backed by a 6-year manufacturer warranty, the Epoch 12V 314Ah Eco Series provides the perfect balance of power, reliability, and efficiency for those who demand the best in off-grid and marine energy solutions.
