Panasonic Ncr21700t Datasheet Jun 2026

The cell must be charged within the temperature range of . Charging outside these limits can cause irreversible damage, including lithium plating on the anode, which reduces capacity and poses a safety risk.

4.8A (1.0C). High charge currents accelerate degradation. Discharge Profile

Used in solar backup walls and uninterruptible power supplies (UPS) due to its predictable cycle life.

As one verified vendor explains: “Tesla spec Panasonic 21700 batteries are of a higher spec than our Panasonic NCR21700T batteries. Tesla spec has a max discharge of 30 A, ours only has a max discharge of 10 A“. panasonic ncr21700t datasheet

If you are into high-performance flashlights, DIY power walls, or electric vehicles (ironically), you have likely heard of the .

Disclaimer: These values are typical specifications and not guaranteed for every cell. Always use a proper Battery Management System (BMS) when designing with 21700 cells.

-20°C to 20°C (At roughly 40-50% State of Charge) The cell must be charged within the temperature range of

Based on official NCR21700 datasheets and technical specifications from BDtronics , here are the core electrical and physical parameters: Specification Typical Capacity Rated/Minimum Capacity 4800mAh – 4900mAh Nominal Voltage 3.6V – 3.7V Max Charge Voltage Discharge Cut-off Voltage 2.5V – 3.0V Max Continuous Discharge 10A to 30A (Depending on variant/temp) Peak Discharge Current Cycle Life 500 – 1000+ cycles Weight ~65g – 70g Dimensions 21.1mm (D) x 70.4mm (H) Performance Characteristics NCR21700 data sheet

Lithium-ion cells store immense energy and require strict handling protocols.

1.5A to 2.4A (0.3C to 0.5C equivalent).

Under , internal resistance causes "voltage sag." While the cell can handle these loads, sustained high-current draw increases internal temperature and reduces overall efficient runtime. 4. Lifecycle and Degradation

The Panasonic NCR21700T is a premier choice for designers looking to maximize runtime and energy density in their products. As seen in the detailed specification overview, its 4800-5000mAh capacity makes it an industry leader for high-capacity applications.

As a high-capacity lithium-ion cell, the Panasonic NCR21700T must be handled with care. High charge currents accelerate degradation

. This durability is crucial for outdoor applications like electric vehicles and e-bikes. D. Long Cycle Life

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:
