The discharge curves provided in the Panasonic NCR21700T data sheet show a relatively flat discharge profile, which is characteristic of high-quality NCA chemistry. The voltage stays above
The datasheet reveals that the NCR21700T is engineered for high-energy applications. It uses a specialized Nickel-Cobalt-Aluminum (NCA) chemistry, known for delivering high capacity and stable voltage plateaus. Specification 21700 (21mm Diameter x 70mm Length) Manufacturer Panasonic / Sanyo Model Chemistry NCA (LiNiCoAlO2) Nominal Capacity 4800 mAh (Typical) / 4700 mAh (Minimum) Nominal Voltage Charging Voltage 4.20V ± 0.03V Discharge Cut-off Voltage Standard Charge Current 1.5A to 2.4A Maximum Continuous Discharge Current
Cordless drills, high-torque impact wrenches, and outdoor power gear benefit from the sustained discharge rate.
15A to 20A (Depending on thermal management) Standard Charge Current: 1.5A to 2.4A
Only use a dedicated Li-ion charger with CC/CV (Constant Current/Constant Voltage) protocol.
E-bikes, electric scooters, and light electric vehicles.
is optimized for high-power output without massive voltage sag
Regularly check the outer plastic wrapping and top insulator ring. If the wrap is torn or scratched, expose of the cell or re-wrap it immediately to prevent short circuits.
