Panasonic Ncr21700t Datasheet Hot [95% ESSENTIAL]

Let’s crack open the official Panasonic NCR21700T datasheet and separate the scorching performance from the literal heat.

The official safety data sheet notes that the NCR21700T has a thermal runaway threshold starting around (248°F–266°F).

: Subjecting the NCR21700T to structural environments exceeding 80°C destabilizes the Solid Electrolyte Interphase (SEI) layer, risking a thermal runaway event. Charge and Discharge Behavior Analysis The CC-CV Charging Profile

Here are the key features and specifications of the Panasonic NCR21700T: panasonic ncr21700t datasheet hot

But here is where the "hot" part comes in:

. Renowned for power density and thermal stability, this cell bridges the gap between massive energy storage and aggressive current draw.

What is the of your motor or inverter?

This is an (flat top) cell. It does not have a built-in protection circuit (PCM/PCB) and must be used with external battery management systems to prevent overcharging, over-discharging, and short circuits.

Heat is the primary enemy of battery longevity.

during high-drain operation to prevent permanent degradation or thermal runaway. Charge and Discharge Behavior Analysis The CC-CV Charging

The datasheet specifies a maximum operating temperature of 60°C for the case . If you measure the metal can and it reads 65°C, you are outside of the warranty spec. At 70°C, the separator inside the cell begins to shrink. This is the physical mechanism that causes a short circuit. A hot NCR21700T is not just uncomfortable; it is structurally failing.

: Approximately 21.1mm in diameter and 70.4mm in length (Flat top style). Thermal & Safety Characteristics

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. This is an (flat top) cell

When analyzing the Panasonic NCR21700T datasheet , a few critical core figures stand out. These parameters dictate exactly how the cell operates under extreme electrical and thermal conditions: NCR21700 data sheet
