Panasonic Ncr21700t Datasheet Hot Fix Here

Due to its 5000mAh capacity and moderate (15A) discharge rating, this cell is ideal for:

The key takeaway from the datasheet is its impressive packed into a slightly larger 21700 form factor, making it ideal for devices that need to run for extended periods on a single charge.

It supports continuous discharge rates typically ranging from 10A to 15A , with some pulse capabilities reaching higher under specific thermal management conditions.

The NCR21700T uses Panasonic’s chemistry. While NCA offers high energy density (hence the 5000 mAh), it has inherently higher internal resistance than the newer Lithium Manganese Nickel (LMN) or Lithium Iron Phosphate (LFP) cells. When you pull 15A from an NCA cell, the Joule heating effect (I²R) is pronounced. panasonic ncr21700t datasheet hot

The NCR21700T balancing act favors continuous power output alongside high capacity.

Thermal / "hot" related limits and safety notes:

When discharged at 15A continuous, the cell temperature will rise significantly. Due to its 5000mAh capacity and moderate (15A)

: During high-rate discharge (e.g., 20A+), internal resistance can cause significant surface temperature increases. For safety, these cells should be monitored to ensure they do not exceed a surface temperature of 60°C during operation.
