Panasonic Ncr21700t Datasheet Hot Repack [ Linux Simple ]
Max Continuous Discharge Current: 30A - 35A (depending on thermal management)
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. panasonic ncr21700t datasheet hot
Peak Discharge: Capable of higher bursts, though this significantly increases heat. End-of-Discharge Voltage: 2.5V (Standard cut-off) Thermal & Safety Guidelines Max Continuous Discharge Current: 30A - 35A (depending
Key Features and Specifications
Nominal Specifications and the "Hot" Threshold
At 20°C ambient, the NCR21700T datasheet specifies a nominal capacity of 4.0 Ah to 4.2 Ah with a nominal voltage of 3.6V. The "hot" classification arises from its maximum continuous discharge rating: 15A to 20A (depending on temperature cutoff settings). Unlike lower-impedance cells (e.g., Molicel P42A), the NCR21700T operates near its thermal limit at 20A. The datasheet explicitly warns that continuous discharge at >15A will elevate the cell surface temperature beyond 60°C, a critical threshold where cycle life degrades exponentially. High capacity : The NCR21700T has a nominal
- High capacity: The NCR21700T has a nominal capacity of 4000mAh, making it suitable for applications requiring high energy density.
- Long cycle life: Panasonic claims a cycle life of up to 500 cycles (80% DOD), which translates to a relatively long lifespan.
- High discharge rate: The battery cell can handle high discharge currents, with a maximum continuous discharge current of 20A.
- Good thermal performance: The NCR21700T operates within a wide temperature range (-20°C to 60°C), making it suitable for various environmental conditions.
The Panasonic NCR21700T is a high-performance lithium-ion cell widely recognized for its "Tesla-grade" energy density and high current capabilities. While official public datasheets can vary by OEM partner, the following technical write-up summarizes the core specifications and critical thermal handling requirements.
