Panasonic Ncr21700t Datasheet Hot [new] May 2026

The Panasonic NCR21700T is a high-performance lithium-ion cell widely regarded as a premium choice for high-drain applications such as electric vehicles, power tools, and robotics. Utilizing a Nickel-Cobalt-Aluminum Oxide (NCA) cathode chemistry, this cell is engineered for high energy density and thermal stability. Core Technical Specifications

is a high-capacity 21700 lithium-ion cell, frequently favored for industrial and high-drain applications such as power tools and e-bikes due to its 5000mAh capacity and robust discharge capabilities. Key Specifications Nominal Capacity: 4800–5000 mAh Nominal Voltage: 3.6V

Rule of Thumb from the Datasheet: For continuous operation below 55°C ambient, derate the 35A limit to 25A. Save the 35A for short 5-second bursts (like taking a hit from a vape or accelerating an e-scooter). panasonic ncr21700t datasheet hot

Under sustained 10A–15A discharge, the cell temperature can climb into the 55–65°C range pretty fast, especially if there’s no active cooling. The datasheet’s own discharge curves show significant voltage sag at 15A, and temp rise is noted as a limiting factor – not just capacity loss.
