Linkdata INR21700S‑60P 21700 Lithium‑ion Cell

Product Overview

The INR21700S-60P lithium ion cell is a grade-A 21700 6000mAh high power lithium-ion cell purpose-built for high-drain battery pack assemblies.

This cylindrical NCM cell delivers reliable high-current output and wide-temperature adaptability, making it well suited for demanding industrial and portable power applications.

Core Performance Highlights

• True high power output: 60A continuous discharge (80 ℃ temperature cut‑off); 110A /10‑second pulse discharge at 50% SOC, 25 ℃
• Excellent low‑temperature performance: stable discharge capacity even at ‑40 ℃, works well for cold‑climate equipment
• Good cycle durability: ≥80 % capacity retention after 1000 cycles under 1C charge /1C discharge condition
• Verified safety performance, passed GB31241‑2022 test items including short‑circuit, over‑charge, crush, thermal shock, temperature cycling, drop and vibration
• Low internal resistance: AC internal resistance ≤4.5 mΩ; DC resistance ≤13 mΩ (50 % SOC, 10 s discharge)
• Factory fresh grade‑A cells. Shipped at 20‑30 % SOC for safe transportation.
