The SVOLT IXR21700-4400mAh Li-NMC Cylindrical Battery Cell is a premium energy solution engineered to push the limits of power density. Manufactured by SVOLT, a Tier-1 pioneer in high-speed lithium technology, this cell utilizes the advanced 21700 form factor to offer a significant capacity upgrade over traditional cells. It is the preferred choice for engineers building high-energy-density battery packs for the European and North American e-mobility markets.

Key Technical Advantages: The High-Capacity Standard

  • Massive 4400mAh Capacity: With nearly double the energy density of standard 2500mAh 18650 cells, the SVOLT IXR21700-4400mAh Li-NMC Cylindrical Battery Cell allows you to achieve target pack capacity with fewer units. This reduces the complexity of spot welding, minimizes points of failure, and lowers the overall pack weight for portable applications.
  • Low Internal Resistance (≤ 20 mΩ): Optimized for efficiency, the low AC impedance ensures robust power delivery with minimal heat generation. This thermal stability is crucial for sustained performance in high-demand scenarios such as professional-grade electric mountain bikes (e-MTB) and heavy-duty power tools.
  • Standardized Precision Dimensions: Engineered with a precise diameter of 21.6 ± 0.2mm and a height of 71.2 ± 0.2mm, this cell ensures a seamless mechanical fit in standardized 21700 holders and spacers, simplifying the industrial assembly process.
  • Tier-1 Li-NMC Chemistry: Utilizing a stable blend of Nickel, Manganese, and Cobalt, this cell provides an exceptional balance of high voltage, high capacity, and long-term cycle stability, ensuring a longer service life for high-value consumer electronics and vehicles.
  • Elite Consistency by DLCPO: Sourced directly from SVOLT’s world-class automated production lines, every cell guarantees elite-level consistency in voltage and internal resistance, essential for maintaining string balance in large-scale series and parallel configurations.

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. We don’t just sell cells; we ensure your energy systems perform optimally for their entire service life.
