SVOLT IXR21700-4400mAh: The High-Capacity Standard
The SVOLT IXR21700-4400mAh is a premium Li-NMC (Lithium Nickel Manganese Cobalt) cylindrical cell. By adopting the advanced 21700 form factor, it offers a significant capacity upgrade over traditional cells, making it the preferred choice for high-energy density battery packs.
High Capacity (4400mAh): With nearly double the capacity of a standard 2500mAh 18650 cell, you need fewer cells to achieve your target pack capacity. This reduces the number of spot welds and lowers the overall pack weight.
Low Internal Resistance (≤20Ω): The low AC impedance ensures efficient power delivery with minimal heat generation. This is crucial for applications like e-bikes and professional power tools where sustained performance is required.
Standardized 21700 Dimensions: Engineered with a precise diameter of 21.6±0.2mm and a height of 71.2±0.2mm for seamless mechanical fit.
✅ Genuine Grade A Authenticity: We guarantee 100% authentic SVOLT cylindrical cells. Every unit is freshly produced and stored correctly to maintain its performance and a long cycle life of ≥800 cycles.
🎯 Precision Technical Matching: Building a professional pack? DLCPO offers a Free Sorting Service. We match cells by voltage and internal resistance to ensure your series/parallel groups are perfectly balanced.
🌐 Safe Global Logistics: As regulated hazardous goods, we provide compliant DDP (Delivered Duty Paid) shipping to the USA, Europe, and Brazil, managing all UN3480 regulations.
Yes. While an 18650 is 18mm×65mm, the SVOLT 21700 measures 21.6mm in diameter and 71.2mm in length. Please ensure your device or battery compartment is designed for the modern 21700 form factor.
As a high-performance Li-NMC cell, the standard charging cut-off voltage is 4.2V. Using a dedicated lithium-ion charger is essential for maintaining the ≥ 800 cycle life.
Absolutely. If your device supports non-protected flat-top 21700 cells, this model provides a reliable, energy-dense power source that fits a wide array of modern electronic and motive devices.
The SVOLT IXR21700-4400mAh is a high-capacity Li-NMC cylindrical cell. Offering 4400mAh in the standard 21700 form factor, it provides superior energy density compared to traditional 18650 cells. Ideal for building high-capacity battery packs for power tools, e-mobility, and portable electronics.

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: Li-NMC Chemistry (3.6V). Max Charge 4.2V. Do not mix with LiFePO4 cells. Requires spot welding for pack assembly. Do not solder directly to terminals.
