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

This is a bare cell ; it must be used with a Battery Management System (BMS). Developed in partnership with Tesla for long-range EV

Industrial lithium cells lack built-in protection circuits (PCMs/BMS). Operating outside designated limits poses severe safety risks. Operational Range Critical Limit / Risk 0°C to 45°C

When building battery packs with the NCR21700T, a Battery Management System (BMS) must be implemented to protect against: Preventing voltage from exceeding 4.2V.

The Panasonic NCR21700T is a premier choice for designers looking to maximize runtime and energy density in their products. As seen in the detailed specification overview, its 4800-5000mAh capacity makes it an industry leader for high-capacity applications.

The table below represents the most consistent technical data gathered from multiple industry sources and independent verified reports. While slight variations exist, particularly regarding capacity and discharge ratings, the following values represent the authoritative consensus.

When engineers, hobbyists, and battery enthusiasts search for the , they are typically looking for more than just a PDF file. They want voltage curves, discharge ratings, thermal limits, and safety specifications to determine if this cell is right for their next project—whether it’s a high-power e-bike, a DIY power wall, or a professional medical device.

The Panasonic NCR21700T occupies an important niche: high energy per cell in the 21700 mechanical form factor suited to designs where runtime/range and energy density matter more than extreme continuous discharge. Successful use depends on treating the cell as an energy‑centric building block: respect charge/discharge limits, implement robust BMS and thermal management, derate where longevity or safety is critical, and validate real‑world performance through testing and modeling. For high‑power use cases, consider power‑optimized 21700 variants or more aggressive parallelization combined with careful thermal design.

As one verified vendor explains: “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“.
