Additional information

Capacity

The CATL 306Ah LiFePO4 Battery Cell 12,000 Cycles Upgrade is the enhanced successor to the widely used 302Ah model, representing the current pinnacle of long-duration energy storage. Manufactured by CATL, the global Tier-1 leader, this cell has achieved a massive leap in longevity by refining electrolyte and electrode materials. It is 100% cobalt-free and specifically designed for utility-scale energy storage where long-term reliability and lowest LCOE are paramount.

Key Upgrades: The New Benchmark for Utility Storage

  • Extreme 12,000+ Cycle Lifespan: While standard LFP cells offer 3,000 to 6,000 cycles, the CATL 306Ah LiFePO4 Battery Cell 12,000 Cycles Upgrade is engineered for a staggering 12,000+ cycles. This significantly reduces the total cost per kWh over the battery’s entire operating life, making it a “buy once, use for decades” solution.
  • 📉 Ultra-High Efficiency (0.17 ± 0.05 mΩ): Featuring a record-breaking low internal resistance, this cell minimizes energy waste during rapid charging and discharging. This precision engineering keeps your battery bank cooler, more stable, and maximizes round-trip efficiency for large-scale solar backups.
  • 🏗️ Standardized Drop-in VDA Footprint: Retaining the industry-standard dimensions of 71.65mm x 173.93mm x 207.2mm, it serves as a seamless drop-in upgrade for systems currently using 280Ah or 302Ah battery racks. You can increase your system’s total energy capacity and lifespan without changing hardware or enclosures.
  • 🏢 Purpose-Built for Utility-Scale ESS: The 306Ah model is the gold standard for grid-frequency regulation, large-scale commercial ESS, and mission-critical backup power. Its robust prismatic aluminum shell provides superior structural integrity and high thermal stability.
  • 🏅 Tier-1 Automotive Pedigree: Every 306Ah cell sourced from DLCPO is Grade A quality, benefiting from CATL’s world-leading automated production and rigorous consistency testing. This ensures that even in massive multi-megawatt strings, each cell remains perfectly balanced.

Battery Applications

Solar & Renewable Energy

Residential and commercial ESS, off-grid solar systems, and micro-grids.

Electric Mobility (EV/AGV)

High-power cells for EVs, electric buses, forklifts, and automated guided vehicles.

Marine & Maritime Power

Reliable power for electric boats, yachts, and offshore energy storage.

Telecom & UPS Backup

🔋 Standard Charging: Only use chargers specifically designed for LiFePO4/LTO chemistry. Do not exceed the maximum charge voltage and current specified in the datasheet.

🌡️ Temperature Range: Do not charge the battery in temperatures below 0°C (unless specified) or above 45°C. Discharge temperature must remain within -20°C to 60°C.

⚡ Short Circuit Prevention: Strictly avoid direct connection between the positive and negative terminals with any metal objects. Ensure terminals are insulated during assembly.

🛡️ BMS Requirement: These are raw cells. A high-quality Battery Management System (BMS) must be installed for over-charge, over-discharge, and thermal protection.

⚠️ Physical Protection: Do not puncture, crush, or drop the cells. If cells show leakage or deformation, stop using them immediately and contact DLCPO Support.

Lithium Battery Sourcing & Service FAQ

❓ Q1: Why should I choose DLCPO Power for my lithium battery projects?

  💡   A: DLCPO Power is a professional, technology-driven distributor specialized in high-grade lithium cells. We are an authorized gateway to industry-leading brands including CALB, EVE, REPT, and GOTION. Unlike standard trading firms, we provide engineering-grade quality control, ensuring every cell is 100% tested and precision-matched for voltage and internal resistance before dispatch.

  💡  A: This is a deliberate strategic choice to protect your battery lifecycle. Batteries stored in overseas warehouses for months suffer from capacity degradation and voltage imbalance. At DLCPO, we operate on a “Zero Aged Stock” model. Every order is fulfilled via made-to-order production or allocated from the absolute latest factory batches. This guarantees you receive 100% fresh Grade A cells with peak chemical activity and perfectly matched performance.

  💡  A: Yes, we provide full technical customization to simplify your assembly. Based on your project requirements, we can professionally process each batch by laser-welding specific terminals (such as standard M6 threaded studs) and providing perfectly matched connecting busbars. Our goal is to ensure your cells arrive “plug-and-play” ready for immediate pack integration.

  💡 A: We offer a streamlined B2B purchasing experience:

  1. Consultation: Confirming cell models and technical specs via dlcpo@dlcpo.com.

  2. Flexible Terms: We support EXW, FOB, and DDP shipping (available for most global regions, handling all customs and import taxes).

  3. Fresh Allocation: Arranging the latest factory batch production.

  4. Testing & Logistics: 100% matching test followed by UN38.3 compliant dangerous goods packaging and global dispatch.

  💡  A: At DLCPO, we firmly believe that receiving payment and delivering goods is not the end of a transaction, but the true beginning of our service value. Our technical team provides continuous post-delivery support, including warranty assistance and BMS configuration guidance. We don’t just sell cells; we ensure your energy systems perform optimally for their entire service life.
