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
-20°C to 20°C (At roughly 40-50% State of Charge)
The NCR21700T is an , not a Power Cell. While its capacity is massive, its recommended continuous discharge current is typically rated around 10A .
Offers high volumetric energy density at 775 Wh/l and gravimetric density at 263 Wh/kg . Performance Characteristics panasonic ncr21700t datasheet
: Features stable NCM (Nickel-Cobalt-Manganese) chemistry and is manufactured by , a leader in battery technology. Technical Specifications
An analysis of the Panasonic NCR21700T is less about a simple cylinder of metal and more about the "quiet revolution" of the energy sector. This specific cell, often described as a modified version of the batteries powering high-performance electric vehicles, represents the peak of modern energy density and power delivery. The Anatomy of Power: Key Specifications NCR21700 data sheet
. This is roughly 40% more than the maximum capacity of the older 18650 standard. Voltage Range: Operates at a 3.6V nominal voltage , with a charging peak of . It is critical to never discharge below to avoid permanent internal damage. Energy Density: It packs a punch with (volumetric) and The Panasonic NCR21700T is specifically known for its
The shift from the traditional 18650 form factor to the 21700 form factor was driven by the need for higher energy density without a massive increase in physical footprint. The NCR21700T excels in several demanding industries:
The most plausible explanation is that while Panasonic does manufacture cells for Tesla under the 21700 form factor, the NCR21700T sold to consumers is a than the cells Tesla integrates into its vehicle packs. As one vendor states: “Tesla spec Panasonic 21700 batteries are of a higher spec than our Panasonic NCR21700T batteries. Tesla spec has a max discharge of 30 A, ours only has a max discharge of 10 A“.
The cell retains a significant portion of its capacity at lower temperatures, though discharge voltage is lower at -10°C compared to 25°C. Typical Applications While its capacity is massive, its recommended continuous
