FAQ

The 37101 LiFePO4 battery cell is suitable for energy storage systems, electric vehicles (such as electric forklifts, electric trucks), high-power UPS equipment, and solar energy storage systems. Its large capacity and long life characteristics make it an ideal choice for scenarios with high energy density requirements.

  • Nominal voltage: 3.2V
  • Capacity: 60Ah
  • Size: standard size, suitable for large-capacity assembly
  • Discharge rate: supports 3C continuous discharge, instantaneous discharge can reach 5C
  • Cycle life: more than 3000 charge and discharge cycles
  • Operating temperature range: -20°C to 60°C

Depending on the application requirements, the battery pack can be assembled in the following ways:

  • Series connection: Increase the total voltage, for example, 16 strings can form a 51.2V system for energy storage applications
  • Parallel connection: Increase the total capacity, for example, 4 and form a 240Ah capacity, suitable for long-term backup power needs

Assembly requires high-performance BMS and precise connection process to ensure safety and reliability.

Yes, the 37101 battery supports 3C continuous discharge and 5C instantaneous discharge, which can meet the start-up and operation requirements of high-power equipment such as electric trucks.

Yes, the BMS is a necessary component for battery pack assembly. It can monitor the status of each battery cell in real time (such as voltage, temperature and current), provide safety protection (such as overcharge, over discharge, over temperature protection), and extend the service life of the battery pack.

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.

This battery maintains stable performance in high temperature environment, and its safety of use is further optimized through heat dissipation design, which is suitable for industrial and outdoor equipment.

Usually, the minimum order quantity is 50 pieces. If a customized battery pack is required, it can be adjusted according to the requirements.

  • Yes, we provide comprehensive technical support, including:
  • Battery pack design and configuration consultation
  • BMS system selection and commissioning support
  • Technical guidance and after-sales support during assembly

During the assembly process, high-quality connection technology, suitable BMS, and sufficient safety tests (such as overcharge, over-discharge, and short-circuit tests) must be used to ensure the safety and reliability of the final product.
