If you exceed 35A (say, a dead short or a mod malfunction pushing 50A), the internal separator melts. This causes an internal short circuit. That heat, combined with the NCA chemistry, leads to "venting with flame."
against other high-current 21700 cells like the or Samsung 50S ? Panasonic NCR2170-M Battery Data, Model and Report
While many resellers publish aggregated data, the definitive source is the official Panasonic datasheet. It's surprisingly difficult to find a live link directly from Panasonic's consumer site, as these documents are often hosted on B2B or industrial component distributor sites. panasonic ncr21700t datasheet hot
Standardly rated at 15A, but often used up to 30A with proper thermal monitoring; peak bursts up to 40A are possible. Dimensions: 21.1mm diameter by 70.4mm height.
At extreme rates like , significant voltage sag occurs early in the cycle due to internal resistance. Designers must adjust low-voltage cutoff parameters to prevent premature equipment shutdown caused by transient voltage dips. Engineering Best Practices for Pack Integration Structural Spot Welding If you exceed 35A (say, a dead short
The ideal storage temperature is 10°C to 25°C at a 40-60% state of charge (~3.7V–3.8V). Key Applications: Why it’s "Hot" on the Market
Running the NCR21700T at elevated temperatures accelerates the growth of the Solid Electrolyte Interphase (SEI) layer, which permanently increases internal resistance and reduces overall capacity. 4. Cycle Life and Storage Guidelines Panasonic NCR2170-M Battery Data, Model and Report While
The Panasonic NCR21700T's specifications make it a versatile component for a wide range of demanding projects.
Heat is generated based on internal resistance and the speed of discharge. The NCR21700T is an , not a Power Cell. This means it has high capacity but does not like "hot" (high amp) loads.
