Panasonic Ncr21700t Datasheet [QUICK WORKFLOW]

The datasheet specifies longevity based on controlled charge-discharge cycling parameters:

Charging to 4.10V instead of 4.20V reduces electrochemical stress, potentially doubling the cycle life. panasonic ncr21700t datasheet

If your load is consistently under 10A per cell, buy the NCR21700T for its capacity and Panasonic’s quality control. If you exceed 12A frequently, step up to a 30A cell like the Molicel P42A. panasonic ncr21700t datasheet
