The EVE 3.2V 304Ah LiFePO4 battery is a brand new, high-performance power cell designed specifically for high-discharge rate applications. Unlike standard energy storage cells, this EV-grade power battery is optimized for instant, high power output, making it the ideal choice for electric vehicles, golf carts, forklifts, AGVs, and heavy construction machinery.
With an ultra-low internal resistance of 0.16mΩ and a max continuous discharge current of 1C (304A), this cell delivers reliable, safe, and efficient performance under heavy loads. We maintain local stock in US, EU (Poland/Russia), and China warehouses to ensure quick delivery for global B2B buyers.
High Power Output: Designed for high C-rate discharge (up to 3C for 60 seconds, 1C continuous 304A).
Ultra-Low Internal Resistance: 0.16mΩ ± 0.05mΩ minimizes heat and voltage sag under high current.
Brand New & 100% Original: Direct from the factory, strictly tested for capacity, voltage, and inner resistance.
Fast Local Delivery: Ready stock in US and EU warehouses ensures quick delivery and avoids long international lead times.
High Safety & Stability: Aluminum shell, wide operating temperature range.
Full Accessory Support: We provide matched BusBars, screws, active battery balancers, smart BMS, and chargers.

| Cell Size | 72*174*200mm |
| Feature | Energy Storage Battery (ESS) | Power Battery (for EVs) |
|---|---|---|
| Primary Function | To store energy for later use. Acts as a power bank. | To provide instant, high power for acceleration and movement. |
| Application | Grid energy storage, home solar systems, backup power. | Electric Vehicles (EVs), electric bikes, power tools. |
| Key Performance Metric | Energy Density (Wh/L) & Cycle Life. Focus on long duration and many charge/discharge cycles. | Power Density (W/L). Focus on delivering high bursts of power quickly. |
| Charge/Discharge Rate (C-rate) | Typically lower C-rates. Slower, more stable charging and discharging over long periods (hours). | Typically high C-rates. Rapid charging and discharging to meet power demands. |
| Cycle Life Requirement | Very High. Designed for thousands of cycles over many years (often 10+ years). | High, but generally less stringent than ESS. Focus on vehicle lifespan (e.g., 8-10 years). |
| System Voltage | Generally higher system voltage (e.g., 400V - 1000V+ for large systems). | Common standards are 400V and 800V platforms. |
| Cost Emphasis | Cost per cycle is the most critical economic factor. | Cost per unit of power (kW) is a major driver. |
| Common Chemistries | Lithium Iron Phosphate (LFP) is dominant due to its safety and long cycle life. | Various, including LFP (increasingly) and NMC (for high energy density). |
| Size & Weight | Less constrained by size and weight; often large and stationary. | Heavily optimized for size and weight to maximize vehicle range and efficiency. |
| Feature | EVE 304Ah Power Battery (e.g., LF304K) | EVE 314Ah Energy Storage Battery (e.g., LF314K) |
|---|---|---|
| Primary Design Purpose | High Power / High C-rate Discharge | High Capacity / Long Duration Discharge |
| Typical Application | Electric Vehicles (EVs), HEVs, high-power tools, robotics. | Stationary Energy Storage Systems (ESS), solar/wind backup, telecom backup. |
| Nominal Capacity | 304 Ampere-hours (Ah) | 314 Ampere-hours (Ah) |
| Key Performance Focus | High Discharge/Charge Rate. Optimized for high current pulses and rapid energy transfer. | High Cycle Life & Energy Density. Optimized for maximum total energy stored and delivered over time. |
| Typical Continuous Discharge Rate (C-rate) | Higher (e.g., 1C to 3C or more continuous). | Moderate (e.g., 0.5C standard, with high-cycle 1C options). |
| Cycle Life | Very good, but secondary to power performance. | Excellent. Designed for thousands of deep cycles (e.g., >8,000 cycles @ 80% DoD, 25°C). |
| Energy Density (Volumetric) | May be slightly lower due to design trade-offs for power. | Higher. Maximizes energy stored per unit volume, a critical metric for ESS. |
| Internal Resistance | Lower. To minimize heat and voltage sag under high current. | Slightly higher than power cells, but still very low for LFP chemistry. |
| Thermal Management | Crucial due to heat generation at high rates. | Less demanding under standard 0.5C operation, but still required. |
| Cost Emphasis | Performance and reliability under stress. | Lowest Cost per Cycle ($/kWh/cycle). Total lifetime cost is paramount. |
| Common Form Factor | Prismatic cell, often optimized for vehicle battery pack integration. | Prismatic cell, often with features for easy stacking in large ESS racks. |
