ETC 280Ah 3.2V Grade A LiFePO4 Prismatic Battery Cell – Industry-Leading 8,000 Cycles – Ultra-Low 0.18mΩ Resistance for High-Performance Solar & Home ESS

Additional information

Capacity

Produced by Wuhu Tianyi Energy Technology Co., Ltd. (ETC), the ETC LFP280Ah-1P LiFePO4 Battery Cell 8000 Cycles is a high-specification prismatic cell designed for maximum efficiency and unprecedented longevity. While sharing the standard 280Ah form factor, its internal chemistry is optimized for extreme durability, ensuring it delivers a significantly lower Levelized Cost of Storage (LCOS) over the multi-decade lifetime of your solar or backup energy system.

Key Performance Advantages: The Hidden Gem of Long-Life Storage

  • Industry-Leading 8,000+ Cycles: Most standard 280Ah cells in the market are rated for 3,500 to 6,000 cycles. The ETC LFP280Ah-1P LiFePO4 Battery Cell 8000 Cycles pushes this boundary to ≥8,000 cycles, translating to over 20 years of daily service in typical off-grid or residential storage applications.
  • Ultra-Low Internal Resistance ($\le 0.18 m\Omega$): Efficiency is the foundation of high-performance systems. With an impedance significantly lower than the industry average (~0.25 mΩ), this cell generates less heat and wastes less energy during high-load operations, maximizing the usable power from every charge.
  • Standardized Universal Fitment: Featuring the industry-standard 174mm x 72mm x 207mm dimensions, these cells are a seamless “drop-in” replacement for existing 280Ah systems. They are fully compatible with most flexible busbars, compression fixtures, and standard DIY rack-mount enclosures.
  • Grade A Prismatic Stability: Each ETC cell is manufactured on fully automated production lines, ensuring strict terminal consistency and superior structural integrity. This level of precision minimizes cell imbalance issues in large-scale series-parallel configurations, extending the health of your entire battery bank.
  • Enhanced Thermal Safety: The robust aluminum casing combined with stable LiFePO4 chemistry provides exceptional safety. Designed to maintain high performance across a wide temperature range, it ensures your energy storage remains online and secure even under demanding environmental conditions.

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

Stable backup power for 5G base stations, data centers, and industrial UPS.

🔋 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.
