If you need 15A continuous, add cooling or lower your current to 10A. If you need 20A+, buy a different cell. Respect the chemistry, and the NCR21700T will deliver 5000 mAh for over 500 cycles. Abuse it, and you’ll learn firsthand why thermal management is the most important line in any datasheet.
The "hot" keyword points to the NCR21700T's ability to run , both in terms of high current and high temperature tolerance. panasonic ncr21700t datasheet hot

At 20°C ambient, the NCR21700T datasheet specifies a nominal capacity of 4.0 Ah to 4.2 Ah with a nominal voltage of 3.6V. The "hot" classification arises from its maximum continuous discharge rating: (depending on temperature cutoff settings). Unlike lower-impedance cells (e.g., Molicel P42A), the NCR21700T operates near its thermal limit at 20A. The datasheet explicitly warns that continuous discharge at >15A will elevate the cell surface temperature beyond 60°C , a critical threshold where cycle life degrades exponentially.
