Panasonic Ncr21700t Datasheet May 2026

The Panasonic is a high-capacity, high-discharge lithium-ion cell designed for demanding applications like electric vehicles, high-drain power tools, and high-performance flashlights. Core Specifications Overview Nominal Capacity 5000mAh (Minimum 4900mAh) Nominal Voltage Max Charge Voltage Max Continuous Discharge 30A (Continuous) / 40A (Peak) Energy Density ~263 Wh/kg Life Cycle Over 1000 cycles Dimensions 21.1mm (D) x 70.4mm (H) Deep Dive Analysis Discharge Characteristics:

is optimized for high-power output without massive voltage sag

. While many high-capacity cells struggle with high currents, this cell maintains a stable discharge curve even at 30A continuous

, which is significantly higher than standard energy-focused cells like the Samsung 50E (rated for ~10A). Charging Requirements: Constant Current-Constant Voltage (CC-CV). Standard Charge Current: 2500mA (0.5C). Temperature Range: Charging should occur between 10 raised to the composed with power cap C 45 raised to the composed with power cap C . Discharging can handle harsher environments from negative 20 raised to the composed with power cap C 60 raised to the composed with power cap C Voltage Cut-off: The safe discharge cut-off for the is typically

. Discharging below this point risks permanent chemical damage to the internal components. Durability and Longevity: This cell is rated for 1000+ cycles panasonic ncr21700t datasheet

, which is exceptionally high for a high-drain cell. To maximize this lifespan, users often choose to charge only to (approx. 80-85% capacity) and avoid deep discharges below www.dnkpower.com Typical Applications Electric Vehicles (EVs):

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

Angle grinders and drills that require sudden bursts of power.

Where both high capacity (runtime) and high current (motor torque) are required. Panasonic's official website : You can try searching

The Panasonic NCR21700T is a high-performance, cylindrical lithium-ion cell designed for high-drain applications that require both high energy density and substantial power output. Often referred to as a "Tesla-style" cell due to its 21700 form factor, it offers a significant capacity jump over traditional 18650 batteries while maintaining a compact profile for battery packs.
