Panasonic Ncr21700t Datasheet Jun 2026

The NCR21700T is a cylindrical lithium-ion cell utilizing the 21700 form factor (21 mm diameter, 70 mm length). Developed by Panasonic, a pioneer in battery technology, this cell features a Nickel Cobalt Aluminium Oxide (NCA) chemistry. This specific formulation allows the battery to achieve high capacity while maintaining a stable thermal profile. Key Highlights:

High discharge capability supports high-drain motor requirements.

When designing battery packs using the NCR21700T, engineers must integrate robust protection mechanisms: panasonic ncr21700t datasheet

One of the most confusing aspects of the Panasonic NCR21700T datasheet is the wide variation in maximum discharge current values reported across different sources. This variation requires careful explanation.

The is the "muscle car" of 21700 cells. It has massive displacement (capacity) and solid horsepower (amps). It is not the absolute highest discharge cell on the market, but it offers one of the best capacity-to-amperage ratios available. The NCR21700T is a cylindrical lithium-ion cell utilizing

. 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

Whether you are designing a high-capacity custom battery pack or evaluating cells for industrial hardware, the core electrical parameters, thermal tolerances, and mechanical geometries found in the official technical documentation define its operation. Core Specifications Overview The is the "muscle car" of 21700 cells

Ensure the charging voltage does not exceed 4.25V and the discharge cut-off is typically 2.5V or higher.

While the world went crazy for the 18650, the 21700 form factor is the new king of capacity and power density. And the NCR21700T? It sits right at the top of the throne.
