Deep Dive: Panasonic NCR21700T Li-ion Battery Datasheet Explained

| 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 | – |

Similar to the cells used in Tesla Model 3/Y packs (though Tesla uses proprietary variations). High-Power Tools: panasonic ncr21700t datasheet

High-end, high-lumen tactical flashlights use 21700 form factors to replace older 18650 standards. Mandatory Battery Management System (BMS) Requirements

Apply a constant current between

The cell is designed for a lower continuous discharge rate, optimized for high-capacity applications. While some sources suggest up to 10A-30A depending on thermal management, typical high-capacity applications utilize this cell at lower continuous currents to maximize run-time.

Used in solar backup walls and uninterruptible power supplies (UPS) due to its predictable cycle life. While some sources suggest up to 10A-30A depending

These specifications are based on general industry datasheets for the NCR21700T model. Feature Specification 4800mAh – 5000mAh Nominal Voltage 3.6V – 3.7V Standard Charge Voltage Discharge Cut-off Voltage Continuous Discharge Current 15A – 30A (varies by source/testing) Peak Discharge Current Cycle Life >1,000 cycles Approximate Weight 65g – 70g Key Characteristics NCR21700 data sheet

The datasheet is honest but incomplete. Always perform your own thermal and cycle-life tests at your intended discharge rate. The 2C limit is real – exceeding it will accelerate aging and may cause cell venting. Feature Specification 4800mAh – 5000mAh Nominal Voltage 3
