For exact ratings (pulse current, internal resistance, detailed charge/discharge curves, temperature ranges, mechanical tolerances, and safety test results), download the official Panasonic NCR21700T datasheet from Panasonic’s technical documentation or authorized distributors.
By understanding the Panasonic NCR21700T datasheet and its specifications, you can unlock the full potential of this exceptional battery cell and create innovative solutions for a wide range of applications.
Never use a cell with a torn, punctured, or peeling outer PVC sleeve. A exposed metal casing acts as a negative terminal; if it touches a positive contact, an immediate short circuit occurs. panasonic ncr21700t datasheet
When designing battery packs, the emphasizes following the mechanical drawing for precise dimensions, particularly regarding the space needed for spot welding terminal tabs. 4. Ideal Applications
The "21700" designation dictates the form factor of the cell. The precise dimensions from the technical drawing are critical to map out physical clearances and busbar arrangements when engineering a physical battery enclosure. Standard Value Maximum Tolerance Height ( ) Weight Electrical Characterization and Discharge Curves The Charging Profile (CC-CV Method) A exposed metal casing acts as a negative
This is a bare cell ; it must be used with a Battery Management System (BMS).
The shift from the traditional 18650 form factor to the 21700 form factor was driven by the need for higher energy density without a massive increase in physical footprint. The NCR21700T excels in several demanding industries: Ideal Applications The "21700" designation dictates the form
While rated for a maximum continuous discharge of 15A, thermal management is required at high currents. At a 15A draw, internal resistance causes Joule heating. Engineers must ensure the cell temperature does not exceed 60°C during continuous operation to prevent accelerated degradation. 3. Cycle Life and Longevity
