The Panasonic NCR21700T is a high-performance lithium-ion battery. It belongs to the 21700 form factor family. This cell balances high capacity with excellent discharge capabilities. It is highly sought after for demanding electronics and electric vehicles.
E-bikes, e-scooters, and electric skateboards benefit from the reduced pack size and weight achieved by upgrading from 18650 to 21700 cells.
Due to its moderate continuous discharge rating, the NCR21700T is : panasonic ncr21700t datasheet
When used appropriately and handled safely, the Panasonic NCR21700T delivers reliable, long‑lasting power backed by one of the most trusted names in battery manufacturing. Whether you‘re building a custom e‑bike pack, upgrading a high‑performance flashlight, or designing an industrial device requiring extended runtime, the NCR21700T remains a compelling choice – provided you understand its capabilities and limitations exactly as detailed in its datasheet.
One of the most confusing aspects of the Panasonic NCR21700T datasheet is the wide variation in maximum discharge current values reported across different sources. This variation requires careful explanation. It is highly sought after for demanding electronics
High-end flashlights, drones, medical devices, and portable computing.
Based on the official specifications for the Panasonic NCR21700T (typically referred to as the ), I have developed a comprehensive technical report. This report is designed to be useful for battery engineers, product designers, and procurement specialists. Whether you‘re building a custom e‑bike pack, upgrading
| Parameter | Value | Reviewers' Take | |-----------|-------|------------------| | | 4800 mAh (0.2C discharge) | Excellent for 21700 format. Slightly above the common 4500-5000 mAh range. | | Nominal Voltage | 3.6V (3.7V typical) | Standard Li-ion. | | Max Discharge Current | 2C (9.6A continuous) / 4C (19.2A pulse) | Major limitation. This is a low-drain cell. | | Standard Charge | 1.4A (0.3C) | Very slow by modern 21700 standards. | | Fast Charge | 3.2A (0.67C) | Still slow. Compare to Samsung 50G or LG M50LT (1C+). | | Max Charge Voltage | 4.20V ±0.03V | Standard, not high-voltage (4.35V). | | Cut-off Voltage | 2.5V | Standard. | | Internal Resistance | ≤ 40 mΩ (AC IR) | Good, but not exceptional (high-power cells are ~10 mΩ). | | Weight | ~69g | Very light for capacity – good energy/weight ratio. | | Operating Temp | Charge: 0~45°C / Discharge: -20~60°C | Standard range. |
The 21700 form factor is larger than the traditional 18650 cell, measuring 21mm in diameter and 70mm in length. This increased volume allows the NCR21700T to deliver significantly higher capacity and power output.
