EVE LF280K vs EVE LF304 vs CATL 280Ah Prismatic LFP Cells: B2B Grading, Rack Assembly & Landed-Cost Comparison

Category: Prismatic LiFePO4 (LFP) Cells & 51.2V Rack Assemblies HS Classification: 8507.60 (Lithium-ion accumulators) Evidence Base: CN→SI, CN→PK, CN→LK SOPs & CN→SE / CN→GT TCO Models (2026-09-21 / 2026-09-22)

Answer-First Verdict: Which Prismatic LFP Cell Wins by Use Case?

Choose EVE LF280K (3.2 V / 280 Ah) when assembling standardized 16S1P 51.2 V / 14.3 kWh residential or light-commercial racks where cycle longevity (6,000 cycles to 80% capacity at 25 °C, 0.5C, 80% DoD) and low upfront rack CapEx (€2,180 EXW for a 14.3 kWh rack) drive project payback.

Choose EVE LF304 (3.2 V / 304 Ah) when higher capacity in a 173.7 × 71.7 × 207.2 mm (5,450 g) footprint is needed, or when scaling 51.2 V banks (7 × 3.2 kWh = 22.4 kWh nameplate / ~20 kWh usable at 90% DoD, EXW $5,600–$8,400) at 0.5C charge / 1C discharge.

Choose CATL 280Ah (3.2 V / 280 Ah prismatic 280K-equivalent) as a dual-source qualification alternate to the EVE LF280K under identical 2.5 V–3.65 V operating windows and ±2% pack capacity-matching tolerances .

3. Decision Framework: When to Choose EVE LF280K vs EVE LF304 vs CATL 280Ah

3.1 Voltage Architecture, Energy Density & C-Rate Matching

Both the EVE LF280K and CATL 280Ah prismatic cell share 3.2 V nominal voltage, 280 Ah nominal capacity, a 3.65 V CC-CV upper charge limit, and a 2.5 V discharge cut-off . Assembled into a 16S1P 51.2 V rack, the 280 Ah class delivers 14.3 kWh per module . Both models serve as architectural equivalents for 51.2 V racks, provided single packs never mix OEMs or capacity bins .

The EVE LF304 increases capacity to 304 Ah at 3.2 V within a 173.7 × 71.7 × 207.2 mm, 5,450 g prismatic can . In 51.2 V / 3.2 kWh modular banks (such as the 7-module, 22.4 kWh nameplate / ~20 kWh usable bank with the Deye SUN-20K-SG04LP3-EU inverter), the LF304 supports 0.5C charge and 1C continuous discharge at ≤ 90% recommended DoD .

3.2 Pre-Shipment OCV, ACIR & Capacity Grading Gates

Across Tradvolt's CN→SI OCV & Capacity Grading SOP and CN→LK Bonded-Warehouse Transfer SOP, buyers enforce three pre-shipment quality gates:

3.3 Customs Classification, Dangerous Goods Transport & RMA Logistics

All three cells classify under WCO HS heading 8507 (subheading 8507.60 — Lithium-ion accumulators), while separate grading instrumentation falls under 9030 . Importers must confirm live tariff rates on EU TARIC, Sri Lanka Customs, or Guatemala SAT prior to entry . Shipments require a UN 38.3 test summary (ST/SG/AC.10/11/Rev.7 §38.3, T.1–T.8), MSDS, and Class 9 packaging under UN 3480 / UN 3481 (plus IATA DGR Section 4 PI 965–970 at 30–50% SoC for air freight) .
