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:
(gravimetric). In simpler terms, it provides more energy per gram than almost any consumer cell of its time. Physical Footprint:
: It is typically manufactured as a flat-top cell, making it easier to spot-weld into large battery packs for e-bikes or EVs. Key Performance Characteristics Understanding the 21700 Battery and Its Specifications panasonic ncr21700t datasheet
The Panasonic NCR21700T is specifically known for its superior energy density, making it a "long-range" cell rather than a pure high-power cell. A. Exceptional Energy Density
The charger applies a steady 1.41A until the cell reaches 4.2V. Physical Footprint: : It is typically manufactured as
Voltage sag is expected. Internal resistance causes initial voltage drops.
The cell is charged at a steady current (typically 0.5C or ~2.4A) until the voltage reaches 4.2V. Exceptional Energy Density The charger applies a steady 1
reservoir in a robust 21700 package. Designing within the guidelines laid out in this datasheet ensures safe operation, maximum lifecycle efficiency, and top-tier power performance.
