Cordless drills, saws, and grinders require the cell's sustained 15A capability.
| Parameter | Value | Reviewers' Take | |-----------|-------|------------------| | | 4800 mAh (0.2C discharge) | Excellent for 21700 format. Slightly above the common 4500-5000 mAh range. | | Nominal Voltage | 3.6V (3.7V typical) | Standard Li-ion. | | Max Discharge Current | 2C (9.6A continuous) / 4C (19.2A pulse) | Major limitation. This is a low-drain cell. | | Standard Charge | 1.4A (0.3C) | Very slow by modern 21700 standards. | | Fast Charge | 3.2A (0.67C) | Still slow. Compare to Samsung 50G or LG M50LT (1C+). | | Max Charge Voltage | 4.20V ±0.03V | Standard, not high-voltage (4.35V). | | Cut-off Voltage | 2.5V | Standard. | | Internal Resistance | ≤ 40 mΩ (AC IR) | Good, but not exceptional (high-power cells are ~10 mΩ). | | Weight | ~69g | Very light for capacity – good energy/weight ratio. | | Operating Temp | Charge: 0~45°C / Discharge: -20~60°C | Standard range. |
