BRIDNA 12.8V 314Ah LiFePO4 Battery – 4019.2Wh Ultra-Large Energy Storage, Built-In Full BMS, High-Capacity Lead-Acid Drop-In Replacement

1. Product Introduction (Official Website Opening Module)

Large-scale off-grid solar systems, luxury RVs, yachts and commercial engineering equipment often suffer from insufficient battery capacity, frequent power cuts and short battery service life. BRIDNA launches the flagship high-capacity 12.8V 314Ah LiFePO4 deep cycle battery, a heavy-duty lithium iron phosphate energy storage solution specially designed for high-power long-duration power demand scenarios.

With a rated capacity of 314Ah and total energy storage of 4019.2Wh, this battery is equipped with a built-in all-round intelligent BMS protection system, housed in a thickened flame-retardant anti-corrosion ABS casing. It can directly replace large-capacity 12V lead-acid batteries, providing ultra-stable, long-cycle and safe power support for large household solar power stations, luxury motorhomes, medium & large yachts, commercial off-grid projects, agricultural equipment and industrial emergency backup power. The product passes CE, FC, RoHS and other global authoritative certifications, becoming the preferred high-capacity energy storage core for global commercial energy storage users.

2. Core Competitive Advantages

2.1 12.8V 314Ah Giant Capacity, 4019.2Wh Mass Energy Storage

Nominal Voltage: 12.8V
Rated Capacity: 314Ah
Total Energy Storage: 4019.2Wh Supports up to 90% deep discharge (DOD), effectively releasing most stored energy. Traditional lead-acid batteries can only discharge up to 50% to avoid irreversible damage, which means this LiFePO4 battery delivers nearly twice the usable power under the same volume specification. The huge energy reserve can continuously supply high-power loads for a long time, greatly reducing the frequency of charging and battery parallel groups for large off-grid systems.

2.2 Built-In Intelligent Multi-Protection BMS System

Marked clearly on the battery shell, the integrated professional BMS realizes all-round safety monitoring and protection of the cell pack:

Overcharge / Over-discharge protection
Over-current / Short-circuit automatic cut-off
High & low temperature charge-discharge limit
Real-time cell voltage balance during charging LiFePO4 material has inherent ultra-high thermal stability, no risk of fire or explosion under high-temperature continuous heavy-load operation, solving the major hidden safety hazards of traditional lead-acid batteries bulging, leakage and thermal runaway.

2.3 3000+ Deep Cycle Lifespan, 6–8 Years Stable Service Life

Adopts Grade A prismatic lithium iron phosphate cells, which can complete more than 3000 full deep charge-discharge cycles, 6–8 times longer than ordinary lead-acid batteries (only 300–500 cycles). For commercial solar power stations and luxury RVs that require daily frequent deep discharge, the capacity attenuation is extremely low, which can significantly reduce the long-term battery replacement and maintenance costs of project contractors and end users.

2.4 Lightweight Integrated Design, Direct Replacement for Lead-Acid Batteries

The whole battery is only 1/3 of the weight of the equivalent-capacity lead-acid battery, effectively reducing the load of motorhomes and yachts to save fuel consumption. The standard shell size and copper terminal layout match most large lead-acid battery installation positions on the market, no structural modification is needed for plug-and-play replacement. The integrated side handle is convenient for two people to carry and install quickly.

2.5 Wide Temperature Adaptability & Heavy-Duty Shockproof Shell

Thickened flame-retardant, corrosion-resistant ABS shell, with excellent shockproof, dustproof and moisture-proof performance. Stable operating temperature range: -20℃ ~ +65℃, adapting to extreme cold mountain off-grid stations and high-temperature desert RV storage environments. Standard thick copper terminals support series-parallel expansion, which can be freely combined into 24V/48V multi-battery energy storage banks to meet the power demand of large off-grid engineering projects.

3. Full-Scenario Application Matching

3.1 Large Household Off-Grid Solar Energy Storage

Matched with high-power solar panels and off-grid inverters to build independent large-capacity household power storage systems, which can support the long-term operation of air conditioners, water heaters, refrigerators and other high-power household appliances during power outages, and maximize the utilization rate of solar energy.

3.2 Luxury RV, Large Motorhome & Caravan Power Supply

The preferred upgrade battery for large luxury RVs, continuously supplying vehicle-mounted air conditioners, large refrigerators, water supply systems, audio-visual entertainment and other high-power electrical equipment during long-distance self-driving travel. Compatible with vehicle alternator charging and solar panel dual charging modes.

3.3 Medium & Large Yachts, Fishing Boats & Marine Engineering

Corrosion-resistant and moisture-proof structure adapts to humid marine working environments, supplying power for ship air conditioners, navigation equipment, refrigeration units and bilge pumps for long-distance ocean sailing.

3.4 Commercial Off-Grid Engineering & Agricultural Equipment

Suitable for rural large-scale solar power stations, agricultural irrigation equipment, field construction machinery and outdoor monitoring base stations, providing stable long-duration power support for unattended commercial projects.

3.5 Industrial UPS & Large Emergency Backup Power

Used as backup power for industrial control equipment, communication base stations and disaster prevention emergency power supply systems, to ensure uninterrupted power supply for key equipment during grid power failure.
