EVE 3.2V 314Ah Rechargeable Lithium Phosphate LifePo4 Battery Cell – New

The EVE MB31 is a high-capacity LiFePO4 prismatic cell built for long-life energy storage, off-grid power, RV and marine battery systems, UPS modules, and large-format battery banks. Unlike high-drain cylindrical cells, this product is optimized around high stored energy, long cycle life, thermal stability, and pack-level serviceability.

The live listing is for a pack of 4 cells with busbars included. A common 4-cell series configuration creates a 12.8V nominal LiFePO4 module with approximately 314Ah capacity and about 4.02kWh nominal energy before BMS, wiring, enclosure, and usable-depth-of-discharge limits.

Key Features:

• 【EVE Grade A 3.2V 314Ah Battery Cell】 Manufactured by EVE’s automated production lines to ensure cell consistency. Nominal capacity: 314Ah (actual measured capacity: 330Ah). Individual cell energy: 1004.8Wh, meeting high energy storage demands. EVE Grade A prismatic lithium iron phosphate cells deliver high energy density and extended cycle life.
• 【Extended Lifespan】Our LiFePO4 cell features a 5000+ cycle lifespan (at 25℃, 0.5C charge/discharge) —that’s 10+ years of reliable use (based on 1 cycle per day). Compared to lead-acid batteries (typically 300-500 cycles), it saves you time and money on replacements, while its low self-discharge rate (<3% per month) means it holds a charge for months without use.
• 【Safety & Wide Temperature Adaptability】This LiFePO4 cell is built with multiple protection mechanisms (overcharge, over-discharge, short circuit, and over-temperature protection) and undergoes 2856+ strict quality control checks during production. It performs reliably in a wide temperature range of -20℃ to 55℃ (-4℉ to 131℉).
• 【High Performance & Easy Integration】With an internal resistance of ≤0.5mΩ, this cell supports 1C continuous charge/discharge and 2C pulse discharge. Its standard size and terminal design make it easy to connect in series (for higher voltage) or parallel (for higher capacity). Please note that the battery cells require connection to a suitable LiFePO4 BMS.
• 【Versatile for Every Application】Designed for both residential and commercial use, this LiFePO4 battery cell is the perfect choice for:Off-grid/grid-tied solar energy storage systems,RVs, campers, trailers, and van life power setups,Marine vessels and trolling motors,Backup power for homes, offices, or communication.Our LiFePO4 cells come with a 2 year warranty, over 10 years of service life.
