Lifespan 8000 cycles, year of manufacture End of 2025/beginning of 2026, original EVE terminal with double screw connection, Supplied with flexible copper connectors made of genuine, highly conductive copper (not aluminum). Actual usable capacity per cell approx. 332-334Ah.

Scope of delivery:

• 8 LiFePO4 cells of type MB31
• including Serial number-related test report (capacity, 3x internal resistance, 3x voltage) for each cell
• including 8 40mm² copper connectors (nickel-plated and specially surface-treated for maximum conductivity, 20x2mm pure copper) with double screw connection, 72mm hole spacing
• including 32x M6 screws with spring washer
• Each terminal has two reinforced M6 threads (stainless steel threaded inserts) for a permanently stable and secure connection.
• Detailed datasheet with technical specifications (available for download)

Characteristics:

• Each cell was individually tested and approved by the manufacturer EVE.
• Each cell was tested multiple times during the production process:
• Capacity check
• Triple voltage test with open circuit voltage
• triple test of internal resistance
• Cells matched for internal resistance and capacity
• Data Matrix code (QR code) for tracking and indicating the production date
• including Serial number-related test protocol for each cell
• Solid terminal with double screw connection for maximum contact area
• Verifiable origin and traceability through Data Matrix code
• High quality: EV Grade (A+), suitable for use in electric vehicles and as battery storage in PV systems
• Nominal energy per cell: 1004.8Wh
• Secure and very stable foam packaging (approx. 23kg per 4 cells)
• The cells exceed the nominal capacity of 314Ah (a full 314Ah is guaranteed to be usable)
• The cells have a storage voltage of approximately 30%.
• 3-year warranty (Warranty conditions)
