EVE MB31 3.2V 314Ah LiFePO4 Prismatic Cell (1,004.8 Wh)
The EVE MB31 is EVE's 3.2V, 314Ah large-format LiFePO4 cell for energy storage. Each cell stores about 1 kWh, so 16 cells in series make a 51.2V, roughly 16 kWh battery, with far fewer cells, busbars and BMS channels than a 100Ah build. MESOL supplies Grade A EVE 314Ah cells direct from the manufacturer, QR-coded with a per-cell test report.

Design notes
- The MB31 is an energy-storage cell rated at 0.5P (about 0.5C). It is not meant for e-rickshaws or other high-current traction packs.
- Cycle-life end points differ by brand: EVE quotes 8,000 cycles to 70% SOH, while Cornex PF173-314A quotes 6,000 cycles to 80% SOH. Compare like with like.
- MB31 is EVE's datasheet name for this 314Ah cell. Some sellers call it “LF314” or “MB314”.

FAQ
Frequently asked questions
Is the EVE MB31 the same as the 'LF314'?
EVE's own datasheet for its 314Ah energy-storage cell is titled MB31. Many sellers call 314Ah EVE cells 'LF314'. Check the model code printed on the cell and the test report.
How many EVE 314Ah cells make a 16 kWh battery?
16 cells in series give 51.2V × 314Ah = about 16.08 kWh nominal.
What is the cycle life of EVE 314Ah?
EVE's MB31 datasheet gives 8,000 cycles to 70% state of health at 25°C, 0.5P charge and discharge.
