Product Overview

The EVE MB31 is a 3.2V 314Ah prismatic LiFePO4 battery cell that delivers 1004.8Wh of nominal energy – a compact powerhouse for modern energy storage systems. Its exceptionally large capacity and ultra‑low initial internal resistance make it the go‑to choice for assembling high‑capacity battery packs in residential, commercial, and utility‑scale storage projects.

Under standard 25°C operating conditions, the MB31 supports 0.5P continuous charging and discharging (both standard and sustained duty), ensuring reliable performance with minimal heat generation. In accelerated cycle‑life tests, this cell maintains 70% state of health (SOH) after 8,000 full charge‑discharge cycles – a benchmark that significantly reduces levelised cost of storage (LCOS) and extends system lifetime.

Whether you are designing off‑grid solar storage, grid peak‑shaving, or backup power solutions, the EVE MB31 combines energy densitycycle durability, and low impedance to meet the most demanding requirements.

Frequently Asked Questions

What is the energy of one EVE MB31 cell?

One MB31 cell provides 1004.8Wh of nominal energy at 3.2V and 314Ah.

How many cycles can the EVE MB31 provide?

The specification states 8,000 cycles at 25°C under the defined test
conditions, ending when the cell reaches 70% state of health.

Can the MB31 be used for solar energy storage?

Yes. It is suitable for residential, commercial, industrial,
grid-tied and off-grid energy storage battery systems.

Does a battery pack using MB31 cells require a BMS?

Yes. A compatible BMS is required to monitor cell voltage,
current, temperature and balancing during operation.

Is compression required during battery pack assembly?

Yes. The battery pack structure should provide suitable cell fixation
and compression according to the EVE application requirements.

Is Poland warehouse stock available?

Yes. Ready stock is available from our Poland warehouse for eligible
European orders, subject to real-time inventory confirmation.
