Panasonic Ncr21700t Datasheet Hot !full!

The primary driver of thermal behavior is the cell's internal resistance (DCIR). Panasonic's datasheet lists typical DCIR at 1 kHz as ≤ 20 mΩ, but under DC load at 15A, effective resistance rises to ~25 mΩ due to polarization. Joule heating (P = I²R) at 15A yields approximately 5.6W of internal heat. This heat must be conducted through the jellyroll to the can wall. The datasheet’s thermal derating curve shows that at 20A continuous, surface temperature hits after 10 minutes in still air—exceeding the recommended 60°C operating window for longevity.

cells due to its 21700 form factor and 5000mAh capacity, finding an official "public" datasheet directly from Panasonic can be difficult as these cells are primarily produced for high-volume industrial and automotive clients. Core Specifications panasonic ncr21700t datasheet hot
