Situation
Your engineering team is sourcing 280Ah prismatic LiFePO4 cells for OEM battery pack manufacturing or ESS integration. You need consistent electrical performance, tight capacity binning, and a supply partner who can deliver traceable Grade A cells with full certification documentation.
The Challenge
The 280 Ah segment is where counterfeit risk concentrates: rewrapped or B-grade cells sold as Grade A, sandpapered QR codes, and capacity claims no batch report supports. Packs assembled from mismatched cells drift apart within months — uneven aging, early balancing losses, and warranty disputes that trace back to cells nobody can document.
How do you select a reliable 280Ah LiFePO4 cell supplier for OEM packs that ensures consistent quality, European delivery, and engineering support?
Our Answer
SSL 280Ah Standard Series cells (LFP280K-V1/V3) deliver verified performance through Grade A cell sourcing with full lot traceability, factory-level capacity matching (≤0.25 mΩ ACIR), and comprehensive test documentation — so your engineering team qualifies a cell once and scales across projects. With Poland Local Warehouse stock and compliance documentation aligned before splicing, we reduce the sourcing risk.
Grade A Cell Traceability
Every LFP280K cell is sourced directly from EVE and Cornex with full lot traceability. Incoming inspection and capacity binning ensure consistent performance — eliminating batch variation that causes field failures.
Electrical Performance Verification
Factory-level test documentation including capacity, ACIR (≤0.25 mΩ), and self-discharge data is provided with every batch, enabling your team to verify cell quality before integration.
European Logistics & Compliance
Poland Local Warehouse supports 3-7 Days DDP delivery for qualified programs. Compliance documentation — CE, UN38.3, MSDS — is aligned to ensure clear EU import and delivery.
