Key Characteristics
- 7.4V nominal voltage from two 3.7V 18650 cells in series
- Operating voltage range: 6.0V (discharge cutoff) - 8.4V (full charge)
- Stable voltage output with minimal fluctuations
- Requires dedicated 2S lithium battery charger (8.4V cutoff)
- 2000mAh nominal capacity (measured at 0.2C discharge rate)
- 5C continuous discharge rate (10A max continuous current)
- 15A instantaneous pulse discharge current (within 10 seconds)
- 0.5C-1C recommended charging rate (1A-2A current)
- 500-1000 standard charge-discharge cycles (to 80% capacity)
- ≤100mΩ total internal resistance (including protection board)
- Built-in protection against overcharge, over-discharge, overcurrent, and short-circuit
Performance Features
Discharge Characteristics
Continuous discharge at 5C rate maintains 90%-95% of nominal capacity. The discharge curve is smooth with slow voltage drop in mid-to-late stages, ensuring stable device operation.
Cycle Life
Standard cycles: 500-1000 (to 80% capacity). High-rate (5C) discharge reduces cycle life to 70%-80% of 0.5C discharge performance.
Safety Protection
- Overcharge protection: 8.45V±0.05V
- Over-discharge protection: 5.8V±0.1V
- Overcurrent protection: 12-15A threshold
- Short-circuit protection: ≤10ms response time
Applications
- Small Power Tools: Handheld drills, mini grinders requiring high-power motor drive
- Consumer Electronics: Toy cars, drones, model airplanes needing 7.4V power
- Emergency Power: Small UPS systems, emergency lighting equipment
- Medical Equipment: Portable monitors, analyzers requiring stable voltage
