Safety & warning

• The product should be stored in a clean, dry and ventilated warehouse with an ambient temperature and a relative humidity of ≤75％. The warehouse should not contain corrosive gases; the product should be away from fire and heat sources (not less than 2m.)
• It is recommended that the cell should be stored at 20% to 50% SOC. When the cell is not used for a long time, charge and discharge it every three months, and charge to 20%~50% SOC to avoid over discharge and affect its performance.
• Do not immerse the cell into water or other conductive liquids.
• It is forbidden to put the cell into fire or expose it to the environment beyond its working temperature range for a long time. If the working temperature of the cell exceeds the maximum operating temp, stop its operation!
• Connect the positive and negative poles of the cell strictly in accordance with the signs and instructions. No reverse charging!
• When the electrolyte leaks, avoid contacting the electrolyte to skin and eyes. In case of contacting, wash with plenty of water and seek medical advice. It is forbidden for any person or animal to swallow any part of the cell or the substance contained in the cell.
• Protect the cell from mechanical vibration, collision and pressure impact, otherwise the cell might be short-circuited, causing high temperature or fire.
• Strictly forbidden to subject the cell to excessive mechanical shock.
• Squeeze, drop, short circuit, leakage and other abnormal problems is strictly forbidden during cell operation.
• During use, it is strictly forbidden to contact the cover of cells directly or connect them together via conductors to form a circuit.
• Cells should be stored and used in a place away from static electricity.
• During operation, charge, discharge or storage, if the cell suddenly heats-up, emits odor, discolors, deforms or has other reactions, it should be stopped immediately and treated accordingly.

Cornex 472Ah LiFePO4 Battery Cell: Technical & Application FAQ

1. Performance & Technical Advantages

Q1: What are the primary technical advantages of the Cornex 472Ah cell?

TL;DR: The Cornex 472Ah is a high-density cell optimized for Long-Duration Energy Storage (LDES), offering nearly 1.5kWh per cell to maximize system integration efficiency. The Details: This cell utilizes an advanced LiFePO4 chemistry specifically tuned for Utility-scale and Commercial Energy Storage Systems (ESS). With a massive 472Ah capacity, it allows for a higher energy-to-volume ratio compared to standard 280Ah or 314Ah cells. This reduces the complexity of the Battery Management System (BMS) and improves overall system reliability by minimizing the number of cells required for large-scale projects.

Q2: What is the expected cycle life and durability of this cell?

TL;DR: Under standard 0.5C/0.5C conditions, the Cornex 472Ah delivers 6,000 to 8,000 deep cycles before reaching 80% SOH. The Details: Thanks to Cornex’s proprietary pre-lithiation and low-expansion material technologies, the cell maintains exceptional stability over time. In a typical commercial ESS environment, this translates to a service life of over 15 years, significantly lowering the Total Cost of Ownership (TCO) for energy investors.

2. System Design & Applications

Q3: Which applications are best suited for the 472Ah capacity?

TL;DR: It is the ideal building block for Commercial & Industrial (C&I) storage, Grid-scale ESS, and high-capacity residential off-grid systems. The Details:

• C&I Storage: The 472Ah capacity simplifies the assembly of 100kWh+ storage containers.

• Residential Power Walls: A 16S configuration (48V nominal) provides a massive 24.1kWh in a single string, perfect for whole-home backup.

• Renewable Integration: High cell-to-cell consistency ensures superior performance in massive series-parallel configurations for solar or wind farms.

Q4: Does Evlithium provide busbars and accessories for the Cornex 472Ah?

TL;DR: Yes, every cell comes with customized flexible copper busbars and flange nuts designed for high-current throughput. The Details: Large-capacity cells like the 472Ah experience slight physical expansion during heavy cycling. Our multi-layer flexible busbars are engineered to absorb this mechanical stress while maintaining low resistance, ensuring safe operation even during continuous high-current discharge (e.g., 230A+).

3. Quality Control & Safety

Q5: How can I verify that I am receiving Genuine Grade A Cornex cells?

TL;DR: Evlithium supplies only 100% Original Grade A cells, each featuring a traceable laser-etched QR Code. The Details: Every cell undergoes rigorous testing for internal resistance, voltage, and capacity consistency before shipping. Customers can verify the production batch via the QR code. We also provide a factory testing report showing that the voltage deviation between cells is typically kept within a very narrow range (under 5mV).

Q6: What safety features are built into the Cornex 472Ah cell?

TL;DR: The cell is designed to meet UL1973 and IEC62619 standards, featuring a high-pressure explosion-proof valve and a reinforced aluminum casing. The Details: To mitigate thermal runaway risks in large-format cells, Cornex optimized the internal tab structure to reduce heat generation. In the event of extreme pressure buildup, the safety valve will release gases in a controlled manner to prevent fire or rupture, ensuring the safety of the entire battery cluster.

4. Strategic Purchasing Advice

Q7: Why choose 472Ah over the more common 314Ah models?

TL;DR: Lower maintenance costs and higher energy density. The Details: Choosing 472Ah cells reduces the number of electrical connection points by approximately 34% compared to 314Ah systems for the same total energy. Fewer connections mean fewer potential failure points (such as loose bolts) and reduced labor costs during installation and long-term maintenance inspections.
