Panasonic Ncr21700t — Datasheet Hot

-20°C to +60°C. High-current draws (above 15A) will generate internal heat rapidly; active cooling is recommended for sustained 30A usage.

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. panasonic ncr21700t datasheet hot

Low internal resistance is a hallmark of the "T" series, which helps minimize heat generation compared to standard high-capacity cells. Common Applications -20°C to +60°C

Here are the key features and specifications of the Panasonic NCR21700T: " it means "At 25°C
