CATL 306Ah: The 12,000-Cycle Heavyweight Champion The CATL 306Ah 3.2V prismatic cell is the enhanced successor to the widely used 302Ah model. By refining the electrolyte and electrode materials, CATL has achieved a massive leap in longevity, offering a cycle life of 12,000 cycles or more. This Lithium Iron Phosphate (LiFePO4) cell is 100% cobalt-free and designed specifically for utility-scale energy storage where reliability is paramount.
Extreme Lifespan: While standard LFP cells offer 3,000 to 6,000 cycles, the CATL 306Ah is engineered for 12,000+ cycles, significantly reducing the total cost per kWh over the battery’s operating life.
Higher Efficiency: With an ultra-low internal resistance of just 0.17 ± 0.05 mΩ, energy waste during rapid charging is minimized, keeping the battery bank cooler and more stable.
Standard Footprint: It retains the industry-standard dimensions of 71.65mm x 173.93mm x 207.2mm, making it a drop-in upgrade for systems using 280Ah or 302Ah battery racks.
✅ Genuine Grade A Authenticity: We supply 100% brand new, Grade A cells with original factory QR codes intact. Every unit can be traced back to the production batch to ensure premium quality.
🎯 Professional Testing & Matching: High-capacity banks require perfect balance. DLCPO tests every cell for capacity, voltage, and internal resistance before shipment to ensure you receive a matched batch.
🌐 Expert Global Logistics: We specialize in DDP (Delivered Duty Paid) shipping to Brazil and other major regions, handling all complex customs clearance and UN3480 dangerous goods documentation for you.
Yes. It offers both higher capacity (306Ah vs 280Ah) and significantly longer cycle life (12,000 vs 6,000). This makes it a much better long-term investment for commercial and industrial ESS projects.
The precise dimensions are 207.2mm (Height) x 173.93mm (Width) x 71.65mm (Thickness). It fits standard VDA footprints used by major ESS manufacturers.
No. You can use any standard 3.2V LiFePO4 BMS. However, ensure your BMS is rated to handle the current requirements of your specific high-capacity application.
The CATL 306Ah is an upgraded version of the popular 302Ah cell. It features advanced LiFePO4 chemistry capable of 12,000+ cycles and ultra-low internal resistance (0.17mΩ), making it one of the most efficient and long-lasting cells for energy storage.

Stop charging cells if charging isn’t completed within the specified time.
Stop using cells if the battery becomes abnormally hot, develops an odor, becomes discolored, deformed, or develops any other abnormal conditions during use, charge, discharge, or storage.
Keep away from fire or hot heat sources immediately when a leakage or foul odors are detected. If liquid leaks onto your skin or cloths, wash it out with plenty of fresh water immediately if liquid leaks from cells and gets into your eyes, don’t rub your eyes. Wash your eyes out with plenty of clean water and seek medical attention immediately.
Notice: To achieve 12,000 cycles, strictly adhere to the recommended compression force (approx. 300kgf) and charging parameters (0.5C).
