EVE LF334 Product Description (OEM MODEL IS GENUINE 340+ Amp Hours)

The EVE LF334 is a high-capacity prismatic Lithium Iron Phosphate (LiFePO4 / LFP) rechargeable cell from EVE Power Co., Ltd. , optimized for demanding power and energy storage applications including electric vehicles, large-scale ESS, and high-rate industrial systems. This is a real model

Capacity and Energy — It provides a nominal capacity of ≥ 334.0 Ah (fresh cell, tested per standard charge/discharge) and nominal energy of ≥ 1075.48 Wh, with a nominal voltage of 3.22 V. This represents a meaningful step up in raw capacity and energy over the earlier MB31 (314 Ah), delivering higher energy density in a similar prismatic footprint (dimensions: 174.0 ± 1.0 mm length × 71.7 ± 0.8 mm thickness under 300 kgf compression at delivery SOC × 207.0 ± 0.5 mm terminal height). Weight is 5,520 g ± 166 g.

C-Rates, Charge/Discharge Performance (key focus areas):

• Standard Charging: Stepped profile for optimal efficiency and longevity — 1C (334 A) from 0–80% SOC, then 0.8C to 3.5 V, 0.5C to 3.6 V, and 0.1C to 3.65 V (at 25 °C ± 2 °C).
• Maximum Instantaneous Charge: Up to 2C for 30 seconds (≤ 80% SOC at 25 °C).
• Standard Discharge: 167 A (0.5C) at 25 °C.
• Maximum Instantaneous Discharge: Up to 3C for 30 seconds (≥ 30% SOC at 25 °C).

This makes the LF334 significantly more capable for higher-power scenarios and pulse loads compared to the MB31’s more conservative 0.5C continuous rating. It also supports a wide operating temperature range (charge: –10 °C to 65 °C; discharge: –35 °C to 65 °C).

Cycle Life — Rated for 4000 cycles to 80% SOH at 25 °C and 2000 cycles at 45 °C (using staged charging to maintain consistent charge duration as capacity fades). It includes detailed pretreatment, clamping, and expansion-force management protocols for module/pack integration.

Other Highlights — Low internal resistance (initial ACR 0.18 mΩ ± 0.05 mΩ; DCR ≤ 1.2 mΩ), robust safety performance (passes over-discharge, over-charge, external short, heating, thermal cycling, and crush tests per relevant GB standards), and comprehensive application guidelines (welding parameters, module design recommendations, thermodynamic data, storage/handling precautions).

Overall, the LF334 is positioned as a higher-capacity, higher-power variant ideal for applications requiring greater Ah throughput and faster charge/discharge capability while maintaining excellent LFP safety and longevity characteristics. It builds on the strengths of earlier cells like the MB31 but with enhanced energy and rate performance.
