Key Features and Advantages
Ultra-High Energy Density
The 50G cell achieves a capacity of 5000mAh, ranking among the highest in the 21700 format. Its energy density is exceptionally high (typically exceeding 700Wh/L), meaning it stores more electrical energy within the same volume. This makes it ideal for applications demanding stringent endurance requirements.
Superior Discharge Performance
Maximum continuous discharge current reaches 9.8A, far exceeding typical high-capacity cells (usually around 5A). This enables the 50G to serve not only low-rate devices but also effectively balance capacity and power demands, making it suitable for equipment requiring instantaneous or sustained high-power output.
Low Internal Resistance
An internal resistance of ≤18.5mΩ ensures minimal voltage drop and heat generation during high-current discharge, enhancing discharge efficiency and safety.

Important Notes
State of Charge (SOC):
- Optimal: Maintain 40-60% (3.7-3.8V per cell)
- Prohibited: Long-term storage at <10% or 100% SOC (accelerates aging)
Temperature Control:
- 15-25°C: Ideal environment (<2% annual degradation)
- -20~45°C: Permissible range (requires SOC control)
- 50°C or <-30°C: Strictly prohibited (hazard risk)
Physical Protection:
- Avoid compression/impact (even with ABS casing)
- Keep away from metal objects to prevent short circuits
Recommendations:
For long-term storage (>1 month), perform periodic brief charge/discharge cycles to maintain lithium-ion activity and ensure normal energy output. We recommend performing a shallow cycle (30%→80%) every 3 months.
