Manufacturer Introduction
The company is the world’s best LFP 280ah supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
CATL is a global leader of new energy innovative technologies, committed to providing premier solutions and services for new energy applications worldwide. CATL began its overseas journey by establishing Contemporary Amperex Technology GmbH (CATG) in Munich, Germany, in 2014. Four years later, CATL founded Contemporary Amperex Technology Thuringia GmbH (CATT) in Erfurt, Thuringia, marking its first global expansion in EV battery manufacturing. CATL is bringing its state-of-the-art technologies to the heart of Europe by localizing innovative battery technology to drive the growth of the region′s EV industry. As a dynamic member of the Thuringian community, CATT is contributing to the concerted efforts of building a sustainable Europe. Thanks to features such as the high reliability, long service life and high energy efficiency of CATL's battery systems, "renewable energy + energy storage" has more advantages in cost per kWh in the whole life cycle.

However, if you choose to purchase LF280K cells, note that the bus bar included with the cells won’t work between LF280K and LF280/LF280N due to differences in positive and negative pole orientation. You’ll need to make additional bus bars.
If this is your first time purchasing 280Ah battery cells, we recommend choosing the EVE LF280K. If you have any questions or concerns, please don’t hesitate to contact us.

📢 NOTE BEFORE PURCHASE
1. One Cell will come with one set busbar, bolt, and washer for free. (e.g. 4 Cells will come with 4 pcs(busbars + bolts + washers) .
2. Each cell shall be used under strict monitoring, control, and protection by the BMS.
3. Before the first use, always charge the cells to full voltage. | FAQ: LiFePO4 battery charging guide.
4. We will match (capacity, voltage, resistance) all cells before delivery.
5. The battery is suitable for DIY lovers with experience.
📢 NOTE BEFORE USING
🟢DO: Pre-install Check! Ensure a thorough pre-installation examination.
• Check the overall physical of each cell and avoid missing accessories. Visually inspect cells for any damage, swelling, leaking, etc. Do not use the cell if the cell casing has been pierced, leaked, broken, cracked, or otherwise visibly damaged.
• Cleaning of the terminals, bus bars, and wire terminal lugs. Ensure cables and terminals are kept clean and free from corrosion, dirt or build-up of any kind, and reduce the resistance between the DC terminal and cable connection.
• Test cell voltage, internal resistance, capacity. Test the voltage, internal resistance with Multimeter and test capacity on each cell individually using a battery analyzer or specialized tester.
• Top balance cells before assembly. Before the first use, always charge the cells to full voltage. We recommend to use chargers specially made for LiFePO4 cells. First charge and initial balancing of the whole pack is important step towards long lifetime.
🚫DON’T:
• Never discharge cells immediately following delivery.
• DO NOT mix cells from various manufacturing series, even if they are of the same type and capacity, and mix old and new cells. Always use cells from the same manufacturing series and delivery batch for every battery.
• DO NOT operate with loose terminal connections.
We guarantee you’ll be happy with cells you purchase from us. When your cells arrive if you’re not completely satisfied or if you suspect the integrity of the cell has been compromised immediately contact our support team via [email protected] for further assistance.
