If you are currently engineering a battery pack with this cell, let me know you are planning (e.g., 10S2P, 13S4P), the maximum continuous current draw your system requires, or what type of cooling/housing you plan to use so we can optimize your thermal and electrical design.

For optimal lifespan and safety, the following charging methods are recommended: CC-CV (Constant Current/Constant Voltage) Standard Current: Max Charging Voltage: Cut-off Current: 5. Ideal Applications The combination of 5000mAh capacity and discharge makes this cell versatile: panasonic ncr21700t datasheet

. The voltage will rise steadily. Keep this phase strictly within the 0∘C0 raised to the composed with power C 45∘C45 raised to the composed with power C

The is a high-performance, cylindrical lithium-ion cell designed for applications requiring a balance of extreme energy density and high discharge capabilities. Often cited as a "Tesla-grade" cell, it is a staple in high-drain power tools, electric bikes, and custom battery packs. Core Technical Specifications Tell me what you need to help narrow down your

of its initial capacity after 300 to 500 full cycles. To significantly extend this cycle life (to 1,000+ cycles), users can implement conservative charging protocols: Limit upper voltage to instead of

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 Ideal Applications The combination of 5000mAh capacity and

When integrating the NCR21700T into a project, the electrical and physical limits defined by the manufacturer must be strictly observed. Below is the data compiled from the official Panasonic datasheet. Electrical Characteristics Specification Typical capacity at standard discharge Minimum Capacity Guaranteed minimum rating Nominal Voltage 3.6V – 3.7V Mid-point of the discharge cycle Charging Voltage 4.20V ± 0.03V Maximum safe upper voltage limit Discharge Cut-off Voltage Minimum safe lower voltage limit Standard Charging Current 1.5A to 2.4A Recommended for maximum cycle life Max Continuous Discharge Current 10A to 15A Dependent on thermal management Physical Dimensions & Weight Diameter: 21.1 mm (Maximum) Length: 70.4 mm (Maximum) Weight: Approximately 68.0 grams Terminal Type: Flat top (Unprotected industrial cell) 3.
