Panasonic Ncr21700t Datasheet Hot

The is a high-performance, industrial-grade lithium-ion cell designed to meet the extreme power demands of modern high-drain applications . Originally developed for automotive and heavy-duty industrial use, this 21700 cell is often referred to as "hot" in the enthusiast community due to its exceptional 40A peak discharge capability and its frequent use in Tesla battery architectures.

When users look for "datasheet hot" information, they are generally interested in how the cell performs under maximum continuous discharge and whether it remains safe and stable when it heats up. Temperature Management & Safety Li-ion battery 3.7V 4800mAh NCR21700T with flat top

But "hot" is not a marketing term; it is a physical reality. If you build a pack with these, you must design for thermal management—nickel strips wide enough to handle current, temperature sensors, and physical spacing for airflow. panasonic ncr21700t datasheet hot

The following data highlights the primary performance metrics typical for the NCR21700 series : Approximately 4800mAh to 5000mAh .

While the NCR21700T manages heat relatively well compared to older cells, when it runs "hot" (e.g., 75°C+), the internal resistance rises, leading to increased voltage sag. This means that as the battery gets hotter, it can deliver less power effectively. Temperature Management & Safety Li-ion battery 3

), expect faster degradation, but the cell is designed with high safety standards and reliable long-term performance.

At a 5C discharge rate, the surface temperature can increase by approximately 45°C in under 10 minutes without active cooling. While the NCR21700T manages heat relatively well compared

The key takeaway from the datasheet is its impressive packed into a slightly larger 21700 form factor, making it ideal for devices that need to run for extended periods on a single charge.

) consistently will accelerate degradation and shorten cycle life.

It is widely cautioned that many cells sold online as "Panasonic NCR21700T" are fakes. One report warns that "the ones sold on Ali are all fake". Authentic cells from certified distributors consistently deliver their rated 5000mAh capacity, while counterfeits often fall far short. Always purchase from authorized, reputable suppliers.
