The engineered using Nickel-Cobalt-Aluminum Oxide (NCA) chemistry . It delivers a rare combination of a 4800mAh to 5000mAh typical capacity and an aggressive 30A continuous (40A pulse) maximum discharge rate .
In the world of lithium-ion cells, the Panasonic NCR21700T is a legend. Co-developed with Tesla for the Model 3, this cell found its way into flashlights, power tools, vapes, and DIY EV conversions. But the keyword "hot" is critical here. This cell runs hotter than its competitors under high continuous discharge. Why? Let’s dissect the official datasheet and real-world test data. panasonic ncr21700t datasheet hot
The is an industry-leading cylindrical lithium-ion battery cell that bridges the gap between massive energy capacity and extreme power delivery . Built using advanced Nickel-Cobalt-Aluminum Oxide (NCA) cathode chemistry, this cell features a 5000mAh nominal capacity paired with a continuous current output threshold peaking at 30A . Co-developed with Tesla for the Model 3, this
4,800 mAh (typical value under standard discharge conditions) Minimum Capacity: 4,700 mAh Nominal Voltage: 3.6V to 3.7V Charging Voltage: 4.20V ± 0.05V Discharge Cut-off Voltage: 2.50V Diameter: Max. 21.15 mm Length: Max. 70.15 mm Weight: Approximately 68.0 grams 2. Charge and Discharge Characteristics the Panasonic NCR21700T is a legend.
A hot topic surrounding the NCR21700T datasheet is its origin. Panasonic does not heavily market a retail version of this exact designation. Community teardowns and data analysis on the Endless Sphere EV Forum reveal that these cells are widely harvested or repurposed from , where they feature ultrasonic aluminum wire-bonding marks on the casing. Because they deliver massive capacities along with massive current delivery at an affordable price, they have become incredibly "hot" in the DIY electric vehicle (EV), e-bike, high-powered flashlight, and custom power pack communities. 📊 Core Technical Specifications Overview
