Attempting to draw more than the rated continuous current (for example, 20A+) will result in rapid voltage sag, excessive heat buildup, and accelerated degradation of the cell. This cell is optimized for range , not speed . It is perfect for an e-bike battery, but potentially unsuitable for a high-power electric dragster.
3.6V (nominal), 4.2V (max charge), 2.5V (standard discharge cut-off). Discharge Current: Continuous: 15A to 25A depending on thermal management. Up to 40A for short bursts. Internal Resistance: Approximately 12mΩ to 20mΩ (DCIR). Form Factor: 21700 (21mm diameter x 70mm height). Approximately 65g to 70g.
