If your cell is currently hot, stop using it. Let it cool. Check your resistance. And remember: When a lithium-ion datasheet says "Max discharge: 35A," it means "At 25°C, with perfect airflow, for 30 seconds, you won't die." For the rest of us, 25A is the new 35A.
Disclaimer: Always consult the official Panasonic NCR21700T datasheet directly from Panasonic’s website for the most current specifications. Lithium-ion batteries carry fire and explosion risks if misused. panasonic ncr21700t datasheet hot
Because the Panasonic NCR21700T operates in a unique and dangerous gray area. On paper, it looks like a monster. In reality, pushing this cell to its limits generates significant heat—and sometimes, a fiery disaster. If your cell is currently hot, stop using it
Why the word hot ?
