15A (With proper temperature monitoring) Discharge Cut-off: 2.5V Internal Resistance: ≤ 15 mΩ (AC 1kHz) 📏 Physical Dimensions & Weight
For context, a standard high-quality 18650 cell typically offers between 3000 mAh and 3500 mAh. By switching to the 21700 format and the NCR21700T chemistry, designers gain nearly 50% more capacity per cell. This reduction in cell count (fewer cells needed to achieve a target Watt-hour rating) simplifies Battery Management Systems (BMS) and reduces welding points, increasing overall pack reliability. panasonic ncr21700t datasheet
