Safety Instructions
Users must use the battery within the operating environment specified in this battery specification sheet. If use outside the specified environment is required, users must consult our company for risk assessment.
- Our company assumes no responsibility for accidents that occur when the battery is used outside the environment specified in this specification sheet.
- The charging current of a single cell should be less than the maximum charging current specified in this specification sheet.
- The charging temperature of the cells must strictly comply with the temperature specified in this specification sheet. Charging above or below the specified temperature range is strictly prohibited.
- When the battery voltage drops to 0V, charging the battery is prohibited.
- The discharge current must not exceed the maximum discharge current specified in this specification sheet. Excessive discharge current will cause cell overheating and rapid capacity degradation.
