Panasonic Ncr21700t Datasheet Hot < 2024 >

At high discharge rates (e.g., 5C), internal temperatures can rapidly exceed 85°C to 94°C without active cooling. Charging Temperature:

Follow these safety rules:

Before diving into the thermal data, here are the baseline specifications for the cell.

is one of the most highly sought-after cylindrical lithium-ion battery cells on the market, blending massive capacity with aggressive discharge performance. Originally made famous due to its association with next-generation electric vehicles (including custom configurations derived from Tesla vehicle battery packs), this cell has become a hot topic among engineers, DIY battery builders, and high-drain device enthusiasts. At high discharge rates (e

Performance reports indicate that testing typically stops if the surface temperature reaches to prevent cell degradation or thermal instability. Discharge Performance Data from the NCR21700 Datasheet shows characteristics for varying current loads: High-Drain Capability: The cell can handle continuous discharge currents of 5A, 10A, 15A, and up to 20A

If your NCR21700T is hot after use, wait 45 minutes before charging. Place it on a metal tray (not a plastic charger) to dissipate heat. Only charge at 0.5C (2.2A) or less. Rapid charging at 5.8A will turn a warm cell into a hand grenade. Originally made famous due to its association with

Heat is often generated at bad connections, not inside the cell.

For high-drain applications that are going to get the cell very hot, it is always recommended to use the Batemo Cell Model for accurate simulation.
