For mechanical design, the datasheet provides exact dimensions:
Unlike some 21700 cells, the NCR21700T has no built-in protection PCB. You must add external overcharge, overdischarge, and short-circuit protection when designing a battery pack.
Rating: 3.5 / 5 – Good for specific use, poor for general high-drain applications.
Buy if: You need a high-capacity 21700 for low-current devices (<3A per cell), long runtime, and minimal self-discharge.
Avoid if: Your load exceeds 5A continuous, or you need fast charging (<1 hour).
Final note to engineers: The datasheet is honest but incomplete. Always perform your own thermal and cycle-life tests at your intended discharge rate. The 2C limit is real – exceeding it will accelerate aging and may cause cell venting.
