Unlock Massive Energy Storage: The Industrial 12V 400Ah LiFePO4 Deep Cycle Battery
Power the most demanding systems with uncompromising reliability. Our 12V 400Ah Lithium Iron Phosphate (LiFePO4) battery, housed in a reinforced ABS enclosure, redefines high-capacity energy storage. Designed for solar farms, marine house banks, and large off-grid installations, it delivers unparalleled runtime, safety, and longevity—where failure is not an option.

Why This 400Ah LiFePO4 Battery Dominates High-Demand Applications:

  • Massive Capacity & Extended Runtime: Store 5.12kWh (12.8V × 400Ah) of usable energy—ideal for powering heavy loads (AC units, inverters, industrial tools) for extended periods without recharging.

  • Extreme Cycle Life: 5000+ deep discharge cycles (to 80% DoD) for 10+ years of service—8X longer than lead-acid alternatives.

  • Military-Grade Safety: LiFePO4 chemistry resists thermal runaway, fires, and explosions. Integrated BMS with cell balancing ensures operational integrity.

  • True 400Ah Usable Capacity: Safely discharge to 100% DoD (vs. 50% for lead-acid), maximizing ROI.

  • Ultra-Rugged ABS Enclosure: Impact-resistant, UV-stabilized, and corrosion-proof for harsh environments (marine, remote sites).

  • 50% Lighter Than Lead-Acid: ~40-45 kg vs. 100kg+—reduces shipping/installation costs and structural strain.

  • Zero Maintenance: No watering, acid leaks, or equalization. Install and operate with confidence.

  • Wide Temperature Tolerance: Operates at -20°C to 60°C (-4°F to 140°F) with stable performance.

  • High Current Capability: Sustain 400A continuous discharge (1C) with 800A (2C) surge support—powers heavy inductive loads.

Compatibility & Installation Notes:

  • Parallel-Ready: Connect 4+ units for 48V/400Ah+ systems (verify BMS parallel support).

  • Drop-in Replacement: Fits standard L16/GC2 lead-acid footprints (confirm dimensions).

  • Certified Safety: UL1973, UN38.3, CE, RoHS compliant.

  • Compatible With: Solar charge controllers (MPPT), inverters (3kW+), and LiFePO4-compatible chargers.

The Ultimate Power Solution for Energy-Intensive Applications:

“When downtime costs thousands per hour—trust the industrial endurance of our 400Ah LiFePO4 battery. Engineered for extremes, backed by science.”
