Panasonic Ncr21700t Datasheet Hot
The datasheet incorporates a and a CID (Current Interrupt Device) . Under abusive "hot" conditions (e.g., short circuit at 80°C ambient), the PTC activates at approximately 90°C, limiting current to <5A. However, for legitimate high-drain use, the datasheet strongly recommends active cooling: airflow of 2 m/s reduces surface temperature by 40% at 15A. Without such cooling, cycle life drops from 500 cycles (to 80% capacity) at 25°C to just 250 cycles at 45°C.
