Standard 21700 cells (like the Samsung 50E) prioritize capacity, maxing out at 9.8A to 15A. The Panasonic NCR21700T is a different beast.
: Demanding cordless equipment that requires consistent high current. Panasonic NCR2170-M Battery Data, Model and Report panasonic ncr21700t datasheet hot
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. Standard 21700 cells (like the Samsung 50E) prioritize
Many vapers and flashlight modders run this cell at 30A+ in pulses. The datasheet is clear: . Push it to 20A, and you will see the surface temperature rise from 25°C ambient to over 80°C within 2 minutes. At 85°C, the separator inside the cell begins to degrade, leading to thermal runaway.
