Due to its high energy density and current output, this cell is a "hot" choice for:
The datasheet mandates that the cell surface must never exceed 60°C during continuous discharge . If an application pushes the cell into high current zones causing it to run hot, active thermal management (forced air or liquid cooling) must be integrated into the battery pack design.
Counterfeit lithium‑ion cells are a real problem in the market. To ensure you get genuine Panasonic cells: panasonic ncr21700t datasheet hot
Cylindrical cells experience internal resistance heating during high-current operations. Managing heat generation is essential for avoiding thermal runaway and preserving cell health. 0°C to +45°C Operating Temperature Range (Discharge): -20°C to +60°C
The cell shows an almost flat voltage curve around 3.6V for most of the discharge, offering almost the full 5000mAh. 10A Discharge: Due to its high energy density and current
The discrepancies (especially for max current) can be attributed to several factors:
Panasonic NCR21700T is a high-performance lithium-ion battery often used in power tools, e-bikes, and flashlights due to its high discharge performance and large capacity. Below are the key specifications and features typically found in its datasheet: Core Specifications : Standard nominal capacity is , with a minimum rated capacity of approximately Nominal Voltage Max Charging Voltage Discharge Cut-off Voltage : Typically To ensure you get genuine Panasonic cells: Cylindrical
1.5A to 2.4A (0.3C to 0.5C equivalent)
: 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
