Panasonic Ncr21700t | Datasheet Hot

) consistently will accelerate degradation and shorten cycle life.

The datasheet mandates that the cell surface must never exceed 60°C during continuous discharge . If an application pushes the cell into high current zones causing it to run hot, active thermal management (forced air or liquid cooling) must be integrated into the battery pack design.

The datasheet generally indicates that cell temperature should ideally stay below for optimal lifespan. Allowing the cell to go "hot" (e.g.,

So why is it running hot?

Whether you are building custom electric vehicle battery packs, maintaining high-drain power tools, or engineering high-performance hardware, understanding the raw engineering boundaries in the Panasonic Datasheet ensures you optimize safety and efficiency. Technical Specifications Matrix

The choice ultimately depends on the application: prioritize capacity for runtime, or current for power. The NCR21700T strikes an excellent balance between the two.

: To prevent overheating or permanent damage, it is critical not to discharge below 2.5V . If the surface temperature exceeds 60°C , discharge should be stopped immediately. Common Applications panasonic ncr21700t datasheet hot

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

-20°C to +60°C. High-current draws (above 15A) will generate internal heat rapidly; active cooling is recommended for sustained 30A usage.

The is a high-performance lithium-ion battery cell originally popularized as a primary component in Tesla Model 3 battery packs. While often difficult to find through official retail channels as a standalone consumer product, it is highly sought after in the DIY EV and flashlight communities for its balance of high capacity and discharge capability.
