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
