Dimension

Product Life Management Requirements:
The service life is limited, and the internal resistance of the battery must be monitored and recorded.
When the internal resistance exceeds 200% of the initial value, the battery should be discontinued.
Safety Performance:
Complies with China’s mandatory lithium-ion battery certification standards, such as GB/T31485-2015.
Clamping force is required; the initial clamping force for a fresh battery should range from 300 to 500 Kgf.
Application Requirements:
The customer must configure a battery management system (BMS) to monitor the battery’s state.
The BMS must meet basic detection and control requirements, such as charge termination, overcharge protection, and discharge termination.
Safety Precautions:
Do not immerse the battery in water, expose it to fire, or expose it to high-temperature environments for extended periods.
Do not short-circuit the battery's positive and negative terminals or reverse charge it.
Avoid overcharging and overheating the battery.
