((free)) - Panasonic Ncr21700t Datasheet Hot

While the NCR21700T manages heat relatively well compared to older cells, when it runs "hot" (e.g., 75°C+), the internal resistance rises, leading to increased voltage sag. This means that as the battery gets hotter, it can deliver less power effectively.

Hey everyone,

Ignore the marketing. Treat the NCR21700T as a cell. If your application requires 35A for more than 10 seconds, buy a different battery (Molicel P42A or Samsung 40T). panasonic ncr21700t datasheet hot

: Varies by source, typically listed at 30A maximum continuous (with peaks up to 40A) in high-drain applications. Some conservative retail listings suggest 10A–15A for optimal longevity. Operating Temperature (Discharge) : -20°C to +60°C Operating Temperature (Charge) : 0°C to +45°C (Standard) While the NCR21700T manages heat relatively well compared

The term "hot" in battery datasheet terms generally refers to a cell operating at its upper temperature limits during high-current discharge. The Panasonic NCR21700T datasheet indicates a discharge range of -20°C to +60°C. However, operating near or exceeding +60°C is considered critical. What Happens When the NCR21700T Gets Hot? Treat the NCR21700T as a cell

So why is it running hot?

While not a "true" ultra-high-discharge cell (like the Molicel P42A), the 20A-30A capability is sufficient for high-drain power tools, personal electric vehicles (PEVs), and high-power flashlights. 5. Typical Applications Panasonic NCR21700T is a versatile cell used in:
