Panasonic Ncr21700t Datasheet 【Fully Tested】
Datasheets provide the foundational boundaries for operating a battery cell safely. Physical Dimensions 21.1 mm (maximum) Height: 70.4 mm (maximum) Weight: Approximately 68.0 grams Form Factor: Cylindrical 21700 Electrical Characteristics Nominal Capacity: 4800 mAh (typical) Minimum Capacity: 4650 mAh Nominal Voltage: 3.6V – 3.7V Charging Voltage: 4.20V ± 0.05V Discharge Cut-off Voltage: 2.5V Current and Temperature Limits Standard Charge Current: 1.5A to 2.4A
Compared to traditional 18650 cells, the 21700 format delivers roughly 47% more volume. This volume increase translates to a disproportionately higher jump in energy capacity and power delivery, often exceeding 50% depending on the specific internal chemistry. It allows engineers to design smaller, lighter battery packs with fewer total cells, drastically simplifying Battery Management System (BMS) wiring and structural design. 2.
