EVE MB31 314AH 3.2v LFP Automotive Grade
Brand new, Auto Grade, and will always be the highest capacity, usually the capacity is approx 335ah, but can be up to 340ah in some batches. We import many containers every year, filled to the brim with EVE batteries. We supply wholesale, so if you are buying in bulk, please contact us for a quote
The next generation EVE Energy MB31 prismatic LiFePO₄ (LFP) cell delivers a nominal capacity of 314 Ah at 3.2 V, storing approximately 1,000 Wh per cell. Built for endurance, it boasts an impressive cycle life of up to 8,000 cycles, making it a reliable candidate for systems expecting a long operational lifespan
These cells feature very low internal resistance (≤0.18 mΩ), supporting efficient charging and discharging with minimal energy loss
With a 0.5 C continuous rating (~157 A) and 1 C (Burst) short duration 30s, they’re well-suited for demanding applications
Robust design elements include operating temperature ranges from –30 °C to 60 °C (discharge) and 0 °C to 60 °C (charge), and they come with safety certifications such as MSDS, UN38.3, CE
This newly released in 2024 next generation EVE 314ah 3.2v Prismatic LFP cell, has been verified by EVE Laboratory to be able to reach 8,000 cycles, this is due to novel manufacturing technology, the secret sauce of LFP chemistry has gone through multiple iterations, the quality of the Cathode and Anode materials has been improved, and it is now expected that under the right conditions, these cells can reach a lifetime of up to 20 years in perfect conditions
