As an unprotected cell, the Panasonic NCR21700T requires careful handling and appropriate safety measures.
Comprehensive Guide to the Panasonic NCR21700T Lithium-Ion Battery
Approximately 70% to 80% of original capacity after 300 to 500 full cycles . Tips to Maximize Cycle Life:
The voltage is held fixed at 4.2V while the current naturally tapers down. Charging terminates once the current drops below a designated threshold (usually 50mA to 100mA). panasonic ncr21700t datasheet
Multiple discussion threads reference the NCR21700T as the cell used in Tesla Model 3 battery packs:
⚠️ This is a draft for reference. Always refer to Panasonic’s official NCR21700T datasheet for production use. Specifications may vary by production date or region.
The cell can sustain high-drain pulses provided the internal cell temperature does not exceed 60°C (140°F) . As an unprotected cell, the Panasonic NCR21700T requires
While the NCR21700T is often rated as a 15A continuous discharge cell "free in air," the datasheet unlocks its true potential under active thermal monitoring:
Fast charging is supported up to higher currents, but it requires strict thermal management to avoid accelerating degradation. Discharge Performance & Thermal Limits
Panasonic’s NCR technology, originating from its collaboration with Tesla, has been refined over years of automotive and consumer battery production, making these cells among the most trusted in the industry. Charging terminates once the current drops below a
The high energy density and respectable current capability of the NCR21700T make it a versatile power source. Its primary use cases include:
To help tailor this information to your project, could you share you intend to power with these cells? I can also provide a detailed comparison against similar cells (like the Samsung 50E or Molicel P42A) if that would help. Share public link
The Panasonic NCR21700T represents a high‑quality lithium‑ion cell that effectively balances capacity with moderate discharge capability. Its primary value proposition is in applications that prioritize runtime over raw power output. However, prospective users must carefully consider:
Regularly inspect the outer PVC shrink wrap for tears to prevent accidental shorts.
: It is typically manufactured as a flat-top cell, making it easier to spot-weld into large battery packs for e-bikes or EVs. Key Performance Characteristics Understanding the 21700 Battery and Its Specifications
