Short Answer: EVE 280Ah LiFePO4 batteries are A-grade lithium iron phosphate cells designed for DIY 12V/24V/48V energy storage systems. Sold in packs of four (3.2V each), they offer 280Ah capacity, 2,000+ cycles, and EU warehouse availability for tax-free, fast shipping. Ideal for solar, RVs, and off-grid setups due to their safety, longevity, and high efficiency.
What Are the Key Features of EVE 280Ah LiFePO4 Batteries?
EVE 280Ah cells use lithium iron phosphate (LiFePO4) chemistry, providing 3.2V nominal voltage and 280Ah capacity per cell. Key features include:
- A-grade quality: Top-tier consistency (±20mV voltage deviation)
- Cycle life: 2,000–5,000 cycles at 80% depth of discharge
- Safety: Non-flammable, stable under overcharge/over-discharge
- EU compliance: UN38.3, MSDS, and RoHS certifications
Why Choose LiFePO4 Chemistry for DIY Battery Packs?
LiFePO4 outperforms lead-acid and other lithium types in safety, cycle life, and thermal stability. These cells operate at 80°C+ without thermal runaway, unlike NMC batteries. With 95%+ round-trip efficiency and 10-year lifespan, they reduce long-term costs for solar or RV applications.

How to Configure 12V/24V/48V Systems with 4 Cells?
Connect cells in series for voltage stacking:
- 12V system: 4S configuration (4×3.2V = 12.8V)
- 24V system: 8 cells (2 parallel sets of 4S)
- 48V system: 16 cells (4 parallel sets of 4S)
Use a 150A BMS for 280Ah cells to prevent cell imbalance. Compression fixtures (6–12 psi) are critical for maximizing cycle life.
When configuring multi-bank systems, busbar sizing becomes critical. For 280Ah cells operating at 0.5C (140A), use 35mm² copper busbars with anti-oxidation coating. Parallel connections require identical cable lengths to prevent current imbalance – even 5cm differences can create 10-15% variance in cell loading. For thermal management, maintain 2mm spacing between cells using nylon brackets to allow air circulation. Below is a recommended configuration table:
| System Voltage | Cells Required | Total Capacity | BMS Rating |
|---|---|---|---|
| 12V | 4 | 280Ah | 150A |
| 24V | 8 | 560Ah | 200A |
| 48V | 16 | 1120Ah | 300A |
What Are the Tax and Shipping Benefits of EU Warehouse Stock?
EU-stocked EVE cells ship without VAT/customs delays to EU countries. Delivery times average 3–7 days vs. 30+ days from China. Includes CE compliance documentation and 2-year local warranty support.
Importing batteries from China typically incurs 19-22% VAT plus €50-150 customs clearance fees. EU warehouse stock eliminates these costs – a 4-cell EVE 280Ah pack priced at €1,200 ships tax-paid, saving €228-264 compared to Chinese imports. Local inventory also reduces shipping risks: lithium batteries from Asia require special IATA-certified air freight costing €80-120/kg, while EU ground shipping costs €25-40 total. Below is a cost comparison for German buyers:
| Origin | Base Price | VAT | Shipping | Total |
|---|---|---|---|---|
| China | €980 | €205 | €175 | €1,360 |
| EU Warehouse | €1,200 | €0 | €35 | €1,235 |
How Does EVE 280Ah Compare to CATL or Lishen Cells?
EVE cells have 5% higher capacity retention after 2,000 cycles vs. CATL. Lishen batteries show ±50mV voltage variance, while EVE maintains ±20mV for balanced packs. Third-party testing shows EVE’s 280Ah cells deliver 285–290Ah actual capacity consistently.
Expert Views
“EVE’s prismatic cell design eliminates welding points found in pouch cells, reducing internal resistance by 15%. Their 0.2C continuous discharge rating (56A for 280Ah) makes them ideal for high-inrush applications like inverters. Always pair with a daly BMS for optimal cell balancing.”
Conclusion
The EVE 280Ah LiFePO4 battery pack offers unmatched value for DIY builders needing reliable, high-capacity energy storage. With EU warehouse availability and robust cycle life, these cells are engineered for performance where cheaper alternatives fail.
FAQ
- Can I mix EVE 280Ah with older batteries?
- No — mixing LiFePO4 with lead-acid or degraded cells causes imbalance and reduces pack efficiency by up to 40%.
- What’s the maximum continuous discharge current?
- 1C (280A) for 30 seconds, 0.5C (140A) continuous. Use temperature sensors above 100A loads.
- How to store unused cells?
- Store at 30% SOC (3.0V/cell) in dry, 15–25°C environments. Recharge every 6 months.
