2x Sunwoda LF314 3.2v 314Ah LiFePo4 Prismatic Cells
Just $50 per cell! You get 2 cells per lot. Cells do not have threaded posts so you will need to laser weld your busbars or, at your own risk, many have successfully drilled and tapped threads no more than 5mm deep.
These batteries are all Brand New SUNWODA 3.2V 314Ah Grade A LiFePO4 prismatic cells, fresh from a 2025 production lot, qualified and RoHS certified as per the included stamp. These are premium energy storage cells from Sunwoda, a leading manufacturer, with excellent matching potential and real-world tested capacities often exceeding nominal—typically 320–335Ah+ (many user reports and seller listings show ~330Ah average for strong performance in builds).
We sell them in convenient 2-packs to make shipping easier and more affordable—customers can easily buy multiples like 4, 8, 12, or 16 cells to build full packs (e.g., 12.8V 314Ah, 25.6V, or 51.2V systems). No accessories included—just the high-quality cells ready for your project.
These cells are rated for 10,000–12,000+ cycles (to 80% SOH at 0.5C charge/discharge, 25°C, under optimized ESS conditions—sources vary from 8,000 to 15,000+ depending on DOD and temp, with many official claims at 12,000 cycles for long-term solar/off-grid reliability and 20+ years calendar life).
• Fully charged - 3.65V
• Fully discharged - 2.5V (or 2.0V at low temps ≤0°C)
• Standard charge/discharge rate - 0.5C (157a)
• Max Continuous Charge/Discharge Current: 0.5C (pulse up to 1C possible in short bursts per similar models)
• Dimensions - approx. 6.85 inches × 2.82 inches × 8.05 inches (174 mm × 71.5 mm × 204–207 mm)
• Weight - approx. 12.3 lbs per cell (5.6 kg ±0.25 kg)
• Internal Resistance - typically ≤0.21 mΩ (low IR for efficient operation and minimal heat)
Key highlights:
• Grade A qualified cells with fresh 2025 production for top performance and longevity.
• High real-world capacity over-delivery (~330Ah common in tests), outperforming many 280Ah/300Ah alternatives.
• Ultra-safe LiFePO4 chemistry—no thermal runaway, excellent stability, dual insulation design.
• Ideal for DIY solar batteries, home ESS, off-grid, RV/marine, or commercial storage—high energy density and efficiency.
