Eco Series LiFePO4 power
High-capacity 4.02kWh lithium storage in a value-focused Eco Series design.
The Epoch 12V 314Ah Eco Series LiFePO4 Battery delivers dependable deep-cycle lithium power for RV, marine, solar, off-grid, backup, and 12V house-power systems. With 314Ah capacity, 4.02kWh of stored energy, 250A continuous output, a 750A peak discharge rating, IP54 weather-resistant protection, and an advanced BMS with low-temperature charge protection, this battery is built for high-capacity lithium performance without unnecessary complexity.
Efficient 12V deep-cycle power for larger energy-storage systems.
The Epoch 12V 314Ah Eco Series LiFePO4 Battery is engineered for users who need more usable energy in a simplified lithium package. Its 314Ah capacity and 4.02kWh energy rating make it a strong choice for larger RV battery banks, marine house-power systems, solar storage, off-grid cabins, mobile power builds, and backup power applications.
The Eco Series design focuses on dependable core performance: high-capacity LiFePO4 cells, a built-in smart BMS, 250A continuous discharge, 250A maximum charge current, IP54 splash-resistant protection, low-temperature charge protection, and maintenance-free operation. This model does not include built-in Bluetooth or internal self-heating, making it a practical option for systems where external monitoring or climate-controlled installation is preferred.
RV, marine, solar, off-grid, and backup power systems.
High-capacity lithium performance with built-in protection.
Recommended add-ons for a complete installation.
Full technical details, dimensions, weight, and charging settings.
Dust protected. Splash resistant. Built for daily use.
The IP54-rated enclosure helps protect the battery from dust and water splashes, making it suitable for many everyday outdoor, mobile, RV, and marine house-power environments. It is weather-resistant for normal use, but it should not be submerged, pressure washed, or installed where standing water can collect around the battery.
More usable energy. Less maintenance. Longer service life.
LiFePO4 technology provides stable voltage output, long cycle life, fast charging capability, and maintenance-free operation. Compared with traditional lead-acid batteries, this Epoch lithium battery delivers efficient energy storage in a lighter package while eliminating watering, acid maintenance, and routine lead-acid service.
Verify your system before installation.
Always confirm battery tray dimensions, Group 31 fitment, cable clearance, terminal compatibility, charger compatibility, and system requirements before installation. Use a lithium-compatible charger, inverter charger, converter, solar charge controller, or DC-to-DC charger programmed within Epoch’s recommended charging parameters. For series or parallel battery banks, use matched batteries of the same model, age, capacity, and state of charge, and follow Epoch’s installation guidelines.
Common questions about fitment, charging, monitoring, and lithium performance.
The Epoch 12V 314Ah Eco Series battery stores approximately 4.02kWh of energy. This makes it a high-capacity option for RV house power, solar storage, marine electronics, off-grid cabins, and backup power systems.
No. This Eco Series model does not include built-in Bluetooth. For app-based battery monitoring, pair the system with an external battery monitor such as a Victron SmartShunt or another compatible shunt-based monitor.
No. This model does not include self-heating. It does include low-temperature charge protection, which helps protect the battery by preventing charging below the safe charging temperature range.
Yes, it can be used as a Group 31 lithium replacement when the tray size, cable clearance, terminal layout, charger settings, and system requirements are compatible. Always confirm fitment before installation.
Use a lithium-compatible charger, inverter charger, converter, solar charge controller, or DC-to-DC charger programmed for LiFePO4 batteries. Recommended settings include 14.2V – 14.4V bulk/absorption, float disabled or 13.3V – 13.6V, equalization disabled, and temperature compensation disabled.
Yes. This model supports up to 4 batteries in series for systems up to 48V and up to 16 batteries in parallel for expanded capacity. Use matched batteries of the same model, age, capacity, and state of charge, and follow Epoch installation guidance.
No. This Eco Series model is designed as a deep-cycle LiFePO4 battery. For engine starting or cranking applications, use a cranking-rated battery or confirm system compatibility directly with Epoch before installation.
The battery has an IP54-rated enclosure, meaning it is dust protected and splash resistant for normal daily use. It should not be submerged, pressure washed, or installed where standing water can collect around the battery.
Three high-capacity 12V LiFePO4 options, each built for a different job: premium marine cranking, heated Bluetooth house power, or value-focused deep-cycle energy storage.
The heavy-duty Group 8D-style option for users who need cranking power, deep-cycle capacity, Bluetooth, internal heating, Victron communications, and IP67 protection.
A more compact heated Bluetooth deep-cycle battery for RV, marine, solar, off-grid, backup, and large 12V auxiliary power systems.
The value-focused high-capacity option with the most stored energy in this comparison, strong 250A output, and simple deep-cycle operation.
Compare capacity, cranking ability, heating, Bluetooth, output, expansion, water protection, size, weight, and warranty before choosing your battery.
