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:
In the consumer market, you won't find an official Panasonic-branded PDF for the "NCR21700T." This is because these cells were primarily manufactured at the Tesla/Panasonic Gigafactory for exclusive use in Tesla battery packs. Most "NCR21700T" cells found in the wild are actually "pulls"—cells salvaged from Tesla modules—or gray-market units. Core Technical Specifications
In this article, we will extract, explain, and expand upon every critical specification from the official Panasonic NCR21700T datasheet. We will also discuss real-world performance, safety precautions, and common applications.
| Parameter | Recommended | Absolute Max | |-----------|-------------|---------------| | Charge voltage | 4.20 V | 4.25 V (risk of plating) | | Standard charge current | 1.5 A (0.3C) | – | | Fast charge current | 3.0 A (0.6C) | 4.0 A (must cut off at 4.20V) | | Trickle charge (below 2.5V) | Do not apply – cell considered damaged | | | Temperature range | 0°C to +45°C | – | panasonic ncr21700t datasheet
Stops operation if any cell drops below 2.5V.
The Panasonic NCR21700T is available through multiple channels, but authenticity is a significant concern:
The datasheet includes a cycle life curve showing: For optimal lifespan and safety, the following charging
High energy density allows for longer range in automotive packs.
While labeled as a "high-capacity" cell, the NCR21700T is capable of handling significant loads. According to technical data, it can maintain a high continuous discharge rate (up to 15A) while keeping voltage sag within reasonable limits, making it excellent for motors and high-drain tools. C. Wide Operating Temperature Range
