EVE MB31 314Ah 3.2V Grade-A Prismatic LiFePO4 Battery Cell

Technical Product Data Sheet (Model/Batch: MB31 / 11416)

The EVE MB31 is an industry-leading, next-generation Lithium Iron Phosphate ($\text{LiFePO}_4$) prismatic cell engineered by EVE Energy, a global pioneer in lithium battery technology. Representing a major upgrade in energy density over classic 280Ah structures, the MB31 packs a massive 314Ah nominal capacity into the exact same physical footprint, archiving an incredible 1004.8Wh (1kWh+) of stored energy inside a single cell.

Manufactured strictly to Grade-A guidelines, this cell is optimized for ultra-low internal resistance ($0.18\text{m}\Omega$) and an extended 8,000-cycle lifespan. It stands as the premier choice for large-scale commercial Energy Storage Systems (ESS), containerized backup grids, high-end residential solar powerwalls, and professional EV conversions.

Core Product Highlights

• Next-Gen Volumetric Density: Fits a massive 314Ah (1kWh+) capacity into the standard 280Ah footprint. This drop-in upgrade boosts a standard 20-foot commercial ESS container from a 3MWh capacity up to a dense 5MWh threshold.

• Elite 8,000-Cycle Durability: Specially treated internal matrix chemistry delivers an exceptional lifecycle profile, sustaining over 8,000 complete charge/discharge loops (at 25°C, 0.5P) before reaching 70% State of Health (SOH).

• Ultra-Low Internal Resistance: Operates at a vanishingly low AC impedance ($\le 0.18\text{m}\Omega$), severely curbing thermal generation under load and maximizing system round-trip efficiency.

• Rugged Aluminum Housing: Features a heavy-duty rectangular aluminum shell built with an advanced explosion-proof safety vent to structural handle high internal compression forces safely.

• Uncompromising Chemical Safety: The LFP structure effortlessly clears strict anti-abuse guidelines (crush, overcharge, puncture, and thermal runaway metrics) without presenting any fire or explosion hazards.
