Multiple sources indicate that there are different versions of the NCR21700T in circulation:

Here’s a for a Panasonic NCR21700T datasheet based on typical specifications for this model (commonly used in high-drain applications). Please verify with an official Panasonic document before final use.

The mathematical and physical parameters of the Panasonic NCR21700T establish its baseline performance metrics under standard testing conditions ( 25∘C25 raised to the composed with power C 5000 mAh (Typical) / 4900 mAh (Minimum) Nominal Voltage: 3.6V Maximum Charge Voltage: 4.20V ±plus or minus Discharge Cut-off Voltage: 2.50V

Do not charge below 0°C. Lithium plating occurs, causing internal short circuits. Also, do not float charge – terminate when current drops to <100 mA. panasonic ncr21700t datasheet

The BMS or mechanical fuses must interrupt circuit flow if the current exceeds the continuous rated limits.

Lithium Nickel Cobalt Aluminium Oxide (NCA) Anode Chemistry: Carbon / Silicon-based Package Style: Flat top (Unprotected industrial cell) Electrical Performance Nominal Capacity: 4800mAh (Typical) / 4700mAh (Minimum) Nominal Voltage: 3.6V to 3.7V Standard Charging Voltage: 4.20V (±0.05V) Discharge Cut-off Voltage: 2.50V

The NCR21700T balances high energy density with respectable discharge currents. Panasonic Model: NCR21700T Format: 21700 (21mm diameter, 70mm length) Nominal Voltage: 3.6V / 3.7V Multiple sources indicate that there are different versions

The datasheet guarantees ≤30 mΩ (AC IR at 1 kHz). Fresh cells often measure 18–22 mΩ. This low IR reduces voltage sag and heating. Over time, IR will rise to ~40 mΩ near end-of-life (500 cycles). High IR is the first sign of a failing cell.

The NCR21700T is engineered with Panasonic’s proprietary Nickel-Cobalt-Aluminum (NCA) chemistry, which maximizes capacity without sacrificing safety. Specification Technical Detail 4800mAh – 5000mAh Nominal Voltage 3.6V – 3.7V Max Charge Voltage Continuous Discharge Current 10A to 30A (application-dependent) Peak Discharge Current Cycle Life 500 to 1,000+ cycles (at 80% capacity) Dimensions 21.1mm (Diameter) x 70.4mm (Height) Weight ~65.0g – 70.0g Key Performance Highlights

Panasonic includes a lengthy safety section. Key points: Lithium plating occurs, causing internal short circuits

The Panasonic NCR21700T (often simply referred to as the NCR21700 or Panasonic 21700 4800mAh/5000mAh) represents a significant advancement in lithium-ion technology designed to meet the growing demand for higher energy density in smaller, lighter packages. As the industry moves from 18650 to 21700 cells, Panasonic’s offering is a premier choice for high-capacity applications.

The cell includes an integrated PTC (Positive Temperature Coefficient) resistor that increases resistance during temperature spikes to prevent short-circuits, alongside a built-in safety valve to relieve internal pressure. Charging and Storage Guidelines

The is a high-performance, cylindrical lithium-ion cell designed for applications requiring a balance of extreme energy density and high discharge capabilities. Often cited as a "Tesla-grade" cell, it is a staple in high-drain power tools, electric bikes, and custom battery packs. Core Technical Specifications
