Panasonic Ncr21700t Datasheet Hot Page
While the NCR21700T manages heat relatively well compared to older cells, when it runs "hot" (e.g., 75°C+), the internal resistance rises, leading to increased voltage sag. This means that as the battery gets hotter, it can deliver less power effectively.
Due to its high energy density and discharge capability, it is frequently used in: Electric Vehicles (EVs):
According to the datasheet, this cell is rated for (and some early revisions even suggested burst rates up to 45A).
The NCR21700T is a 21mm x 70mm cylindrical lithium-ion battery cell with a nominal voltage of 3.7V and a capacity of 4000mAh. It features a high discharge rate, long cycle life, and excellent thermal stability, making it suitable for demanding applications. panasonic ncr21700t datasheet hot

The search query usually comes from one of three user groups:
To avoid a "hot" battery becoming a safety hazard, the Panasonic NCR21700T requires proper management in a pack design:
This article provides a comprehensive overview of the , analyzing its core specifications, performance under load, and crucial information regarding its operating temperatures, especially when the cell gets "hot" during high-drain applications. 1. Panasonic NCR21700T Technical Specifications The NCR21700T is a 21mm x 70mm cylindrical
Cells should be stored at a partial state of charge (30% to 50% SoC, approx. 3.7V to 3.8V) in a cool, dry environment (ideally between -20°C and +20°C) to minimize capacity loss from self-discharge and chemical aging. 5. Applications and Target Use Cases
If you already own these cells and want to push them safely, follow these thermal management rules derived from the datasheet:
