Multiple discussion threads reference the NCR21700T as the cell used in Tesla Model 3 battery packs:

Thanks to its balanced energy density and high discharge rate, the NCR21700T is widely utilized across several sectors. panasonic ncr21700t datasheet

Portable power stations and solar backup systems.

| Parameter | Value | |-----------|--------| | Diameter | 21.0 mm ±0.2 mm | | Height | 70.0 mm ±0.3 mm | | Weight (approx.) | 68 g | The Panasonic NCR21700T is a lithium-ion battery cell

Moderate‑drain power tools that require sustained runtime benefit from this cell‘s capacity.

Optimized for gravimetric density (~263 Wh/kg), providing more runtime for its weight than standard 18650s. Stable Discharge: It sits right at the top of the throne

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.

Suitable for remote‑controlled vehicles, drones, and other high‑performance models.

Due to its moderate continuous discharge rating, the NCR21700T is :
