Panasonic Ncr21700t — Datasheet [upd]

Based on the official specifications for the Panasonic NCR21700T (typically referred to as the ), I have developed a comprehensive technical report. This report is designed to be useful for battery engineers, product designers, and procurement specialists.

The Panasonic NCR21700T is a benchmark lithium-ion cell that, despite its elusive official documentation, has proven its performance in numerous critical applications. For engineers, it represents a known quantity with a high energy density and a strong track record. For hobbyists, it is a powerful and accessible component for DIY projects.

If you want, I can:

The 21700 format offers roughly 50% more volume than standard 18650 cells. Panasonic uses this extra volume to pack advanced chemistry, yielding a gravimetric energy density exceeding 250 Wh/kg. 2. Charge and Discharge Characteristics panasonic ncr21700t datasheet

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

(Note: Designers must account for the natural swelling of the cell—up to 10-15% expansion in diameter—over its lifetime when designing battery packs.)

This makes the NCR21700T ideal for low-to-medium drain long-life applications like solar storage, not for racing drones. Based on the official specifications for the Panasonic

Used in residential solar battery banks and off-grid power stations due to its long shelf-life and density.

Do not expose to temperatures outside the specified range.

Ideal for e-bikes, electric scooters, skateboard conversions, and custom DIY EV packs. For engineers, it represents a known quantity with

Keep in mind that these specifications might not be comprehensive or up-to-date. If you need accurate and detailed information, I recommend finding the official datasheet from Panasonic or a reliable source.
