⚠️ Avoid random PDF hosting sites – many contain old revisions (e.g., 2019 pre-production specs with 12.5A limit). Always verify the revision date.
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. panasonic ncr21700t datasheet
