Yes, this battery cell is optimized to support a wide operating temperature range of -20°C to 60°C. For extremely cold environments as low as -40°C, we can provide customized heating system solutions.

  • UN38.3: Meets international transportation safety requirements
  • CE: Meets EU market requirements
  • UL: Meets international safety standards
  • IEC62619: Battery safety certification suitable for energy storage and industrial applications

Yes, we provide comprehensive customization services, including:

  • Voltage and capacity adjustment (such as 51.2V 300Ah battery pack)
  • Waterproof and dustproof housing design, suitable for use in harsh environments
  • Intelligent BMS system integration, providing real-time data monitoring and remote management functions
  • Check the BMS status regularly to ensure the balance of the battery cells
  • Avoid deep discharge, it is recommended to keep the power range of 50%-60%
  • When stored for a long time, recharge the battery once every three months
  • The storage environment should be kept dry and the temperature range should be between -10°C and 30°C.

Under normal use conditions, this battery can provide more than 3,000 charge and discharge cycles, and the battery pack can last for more than 5 years.

Yes. The maximum charge rate of this battery is 1C (60A), which can complete charging in a short time, significantly improving efficiency.

This battery supports deep discharge and efficient charging characteristics, and can efficiently store and release energy between day and night, making it an ideal choice for home and commercial energy storage systems.
