EVE LF304 3.2V 304Ah LFP Power Battery Spec

This document is the product specification for the EVE Energy LF304 LFP Power Battery, a rechargeable lithium iron phosphate battery with an aluminum shell. It has a typical capacity of 304Ah and a nominal voltage of 3.2V. The specification covers general technical parameters including dimensions (173.5mm width, 72.0mm thickness, 208.8mm height), weight (5.49kg), AC impedance (≤0.5mΩ), and charge/discharge cut-off voltages (3.65V/2.5V). It details standard test conditions at 25±2°C and 15-90% relative humidity. Key performance features include C-rate discharge capacity retention (≥100% at 0.5C and 1.0C), discharge performance at 55°C (≥95%) and -20°C (≥70%), charge retention (≥95%) and recovery (≥97%) after 28 days, and cycle life of ≥3500 cycles at 25°C and ≥1800 cycles at 45°C (1C/1C, to 80% capacity). Safety tests confirm no explosion, fire, or leakage under overcharge, over-discharge, short circuit, drop, heating, extrusion, seawater immersion, temperature cycling, low pressure, and thermal runaway conditions. The battery is suitable for vehicle power supply and storage systems, with recommended SOC window of 10-90% and storage conditions of -20°C to 45°C short-term and 0°C to 35°C long-term.
