EVE MB31 314ah

Upgrade your energy storage systems with the next-generation EVE MB31 314Ah Lithium Iron Phosphate (LiFePO4) prismatic cell. Engineered by industry-leader EVE Energy, the MB31 represents a massive technological leap forward, replacing the older 280Ah standard by squeezing more capacity and an upgraded 8,000 cycle life into virtually the same physical footprint.

​Whether you are assembling a heavy-duty 48V solar power wall, upgrading an Electric Vehicle (EV), or designing a Commercial & Industrial (C&I) backup system, this 1kWh-per-cell powerhouse delivers unmatched efficiency, extreme longevity, and ultimate thermal safety.

​Key Features & Benefits

​Next-Gen Higher Density (314Ah): Get more runtime and higher capacity without increasing the physical size or weight of your custom battery enclosures.

​Ultra-Extended Lifespan (8,000+ Cycles): Featuring advanced chemical stabilization, this cell delivers up to 8,000 cycles under standard factory testing conditions, ensuring 15 to 20 years of reliable daily performance.

​Lowest Internal Resistance (\le 0.20 \text{ m}\Omega): Ultra-low IR ensures minimal heat generation even during heavy continuous discharge, maximizing overall system efficiency.

​Superior Safety Profile: Premium LiFePO4 chemistry completely eliminates the risk of explosion or thermal runaway, making it perfectly safe for indoor residential and commercial installations.

​Heavy-Duty Terminals: Features robust, professional-grade laser-welded terminals designed for secure, low-resistance busbar connections.
