2. Detailed Analysis of Datasheet Parameters

CC-CV (Constant Current-Constant Voltage)

To maximize the lifespan of the NCR21700T, follow the standard charging protocol. Panasonic NCR21700T is a high-capacity lithium-ion cell in

The discharge plateau is what matters. The NCR21700T maintains ~3.6V for most of its usable range. At 5A discharge, the voltage stays above 3.4V until about 80% depth of discharge. At 15A continuous, the voltage sags to ~3.2V early, so higher currents will reduce usable energy noticeably. At 5A discharge, the voltage stays above 3
