Technical note: This is an unprotected bare cell, not a finished battery pack. Use a 3.60 V standard CC/CV charge setting; the safety section separately states that charge voltage must not exceed 3.65 V. Maximum continuous charging depends on cell temperature: 0.2C at 0–10°C, 0.5C at 10–20°C, 1C at 20–45°C and 0.5C at 45–55°C. The 6C discharge value applies for 10 seconds only. Verify actual pack current, cell temperatures, dimensions and protection settings before integration.
