Epoch 12V 334Ah Essential Series LiFePO4 Battery – 4.28kWh
The Epoch 12V 334Ah Essential Series LiFePO4 Battery is a high-capacity deep-cycle lithium battery designed for RVs, camper vans, marine applications, solar energy systems, backup power, and off-grid installations. With 334Ah of capacity and 4.28kWh of stored energy, it provides substantial 12V power in a single battery while reducing the need for multiple smaller batteries.
Built with LiFePO4 (Lithium Iron Phosphate) chemistry, this battery is designed for long-term, maintenance-free operation. It delivers up to 200A of continuous discharge power and can provide a 400A peak discharge for up to 3 seconds, making it suitable for properly sized inverter systems and other higher-demand 12V applications.
Built-In Heating for Cold-Weather Charging
The battery features internal heating to support charging in freezing conditions. This makes it a suitable option for installations that may experience cold-weather conditions.
Bluetooth Battery Monitoring
Monitor your battery directly from a compatible smartphone using the Epoch Li-Ion app for iOS and Android. Bluetooth connectivity provides convenient access to important battery information, including battery status, state of charge, voltage, current, temperature, and cycle information.
Advanced Battery Management System
An integrated Battery Management System (BMS) helps protect the battery against overcharging, over-discharging, over-current, short circuits, and temperature extremes. This provides an added layer of protection while helping maintain reliable battery performance.
Large Capacity in a Compact Package
With 4.28kWh of stored energy, the 334Ah battery provides extended runtime for 12V power systems. Its large-format design can help simplify installations by reducing the number of individual batteries and connections required for a high-capacity battery bank.
Expandable Battery System
The Epoch 12V 334Ah battery can be expanded for larger energy-storage systems. Up to 4 batteries can be connected in series for compatible 24V, 36V, or 48V configurations, while up to 16 batteries can be connected in parallel within the manufacturer’s specified limits.
Weather-Resistant Design
The battery features an IP54-rated enclosure that provides protection against dust and water splashes. It is designed for RV, marine, mobile, and outdoor applications, although it is not intended for submersion.
Long Cycle Life and Maintenance-Free Operation
The LiFePO4 chemistry provides a long service life with 4,000+ cycles. Unlike traditional lead-acid batteries, this lithium battery does not require routine watering or acid maintenance, making it a convenient option for long-term energy storage.
