Panasonic Ncr21700t Datasheet __full__ Jun 2026
Ideal for solar wall storage and home backup power due to its compact energy density.
battery packs, it is also popular in power tools, drones, and e-bikes. TechInsights Core Performance Features High Capacity : Typically rated at (typical) or (minimum). High Discharge Rate : Supports continuous discharge currents of 25A to 30A , with peak pulses up to Long Cycle Life : Designed for durability, often exceeding 1,000 charge/discharge cycles Safety & Stability
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 panasonic ncr21700t datasheet
15A to 30A (Depending on thermal management limits) Cell Style: Flat Top (Industrial bare cell)
The voltage is held fixed at 4.2V while the current naturally tapers down. Charging completes when the current drops below the cut-off threshold (usually 50mA to 100mA). Ideal for solar wall storage and home backup
The Panasonic NCR21700T is a formidable entry in the 21700 form factor (21mm diameter, 70mm length), designed to compete with (and often outperform) the legendary Tesla/Panasonic joint-venture cells. However, unlike Tesla-specific variants, the NCR21700T is available to the general market, making it a favorite among OEMs and advanced builders.
No. It is an unprotected flat-top cell. You must add a protection circuit or use a BMS. High Discharge Rate : Supports continuous discharge currents
Stop charging when the current tapers off to a specified cut-off threshold, typically
When designing battery packs, the emphasizes following the mechanical drawing for precise dimensions, particularly regarding the space needed for spot welding terminal tabs. 4. Ideal Applications
The datasheet includes a cycle life curve showing:
