Eve MB56 Prismatic - 628Ah - LiFePO4 3.2V - Single stud - Grade A-

The EVE MB56 Single stud is a rechargeable prismatic lithium iron phosphate cell (LiFePO4) rated at 628 Ah and 3.2 V, offered as Grade A-. The cells have been sorted by capacity. The model is intended for large stationary storage systems.

For this batch: minimum capacity 680 Ah. The nominal model capacity is 628 Ah.

Grade A- has slightly more variation in capacity and internal resistance than Grade A (though still low). Imperfections in gluing, wrapping, spray coating and alignment are also possible – see the last photo.

EVE has switched to spray-coated cells. You may receive cells wrapped with Malar tape or spray-coated cells. (We try not to mix them.)

The charge and discharge rate is 0.5P at 25 ± 2 °C, equivalent to 1004.8 W at the nominal storage capacity of 2009.6 Wh. Approximately 314 A is only the conversion at 3.2 V. The 8000 cycles down to 70% remaining capacity apply according to the EVE cycle test with the prescribed clamping setup and adjusted power steps.

The recommended compression force is 3000–7000 N. The cell has aftermarket studs and a nickel-coated copper busbar measuring 35 mm wide and 2 mm thick, suitable for up to 360 A.

Note: Internal resistance (IR) was measured before the terminals were installed.
Voltage and current probes were placed on opposite sides of the terminal.
The cell temperature during measurement was usually around 25°C.
Placing the probes closer together, measuring at the terminals or measuring at lower cell temperatures results in higher IR values.
