The Panasonic NCR21700T is a high-performance, industrial-grade lithium-ion cell. It stands out in the 21700 form factor market for balancing high capacity with reliable discharge rates.
As a 21700 cell, it provides roughly 50% more capacity and energy than the older 18650 standard, allowing for longer runtimes in the same relative footprint. Market Reality & Identification panasonic ncr21700t datasheet
If you are currently engineering a battery pack with this cell, let me know you are planning (e.g., 10S2P, 13S4P), the maximum continuous current draw your system requires, or what type of cooling/housing you plan to use so we can optimize your thermal and electrical design.

The Panasonic NCR21700T is a high-energy-density cylindrical Lithium-Ion battery. As an evolution of the 18650 form factor, the 21700 size allows for greater capacity and improved thermal management. The "T" designation typically signifies a specific revision optimized for high capacity and reliable discharge rates, often found in electric vehicles (EVs), energy storage systems (ESS), and high-end industrial applications. This cell offers a balance between volumetric energy density and power capability.
) provides one of the highest specific energy profiles available in mass production. The dominance of nickel drives up the energy density, while cobalt stabilizes the layered atomic structure during cycling. Aluminum acts as a stabilizing modifier, mitigating thermal runaway risks and widening the safe operational window. Anode Technology Safety and Handling The Panasonic NCR21700T is a
Lithium-ion chemistries require strict environmental boundaries to operate safely. The NCR21700T datasheet specifies strict temperature windows for different operational states: 0°C to +45°C Discharge Temperature: -20°C to +60°C Storage Temperature: -20°C to +50°C (less than 1 month) Safety Warnings
This makes the NCR21700T ideal for low-to-medium drain long-life applications like solar storage, not for racing drones.
Yes – a CID (Current Interrupt Device) and a pressure vent on the positive terminal. It activates at ~10–15 bar.
