- Overcharge Protection: 4.25V (typical)
- Over-discharge Protection: 2.5V (typical)
- Current Limiting: 20A (continuous), 30A (pulse)
The Headline Specs (The "Why" Behind the Hype)
- Capacity: 4000mAh (typical), 3800mAh (minimum)
- Nominal Voltage: 3.7V
- Maximum Discharge Current: 20A (continuous), 30A (pulse)
- Maximum Charge Current: 10A (continuous), 20A (pulse)
- Cycle Life: ≥ 500 cycles (80% capacity retention)
- Self-Discharge Rate: ≤ 3% per month (at 25°C)
- Operating Temperature: -20°C to 60°C (charge/discharge)
- Storage Temperature: -20°C to 25°C (≤ 1 year)
- High energy density (optimized for capacity, not low IR)
- Moderate internal resistance (~25mΩ real-world) means ~5–10W of heat at 15A
- Large 21700 format packs heat more than 18650s unless airflow is good
