FAQ

20100 LiFePO4 battery cell is suitable for low-speed electric vehicles, industrial vehicles, backup power supplies, etc. Its high-rate discharge performance and long life are particularly suitable for high-power demand scenarios.

  • Nominal voltage: 3.2V
  • Capacity: 100Ah
  • Size: standard 20100 appearance, easy to assemble
  • Discharge rate: supports 1C continuous discharge, instantaneous discharge can reach 3C
  • Cycle life: more than 3000 charge and discharge cycles
  • Operating temperature range: -20°C to 60°C

WheDuring assembly, you need to select the appropriate series and parallel methods according to the application requirements:

  • Series: increase the total voltage, for example, 16 strings can be used for 51.2V system
  • Parallel: increase the total capacity, for example, 2 and 200Ah capacity

Assembly requires an adapted BMS, and the connection and protection design is completed through professional processes.

Yes, it is highly recommended to be equipped with a BMS. The BMS can monitor the voltage, current and temperature of the battery cell, provide overcharge, over-discharge, over-current and over-temperature protection, and ensure the safe operation of the battery pack.

The 20100 LiFePO4 battery cell performs well and supports an operating temperature range of -20°C to 60°C. For extremely cold (as low as -40°C) or extremely hot environments, we can further optimize its performance through a heating system or heat dissipation design.

The assembled battery pack can support the following certifications:

  • UN38.3 (International Transport Safety)
  • CE (EU Market Compliance)
  • UL (International Safety Standard)
  • IEC62133 (Battery Safety Certification)

Yes, we provide customized services, including the following:

  • Voltage and capacity adjustment (e.g. 48V 200Ah)
  • Customized heating system to meet low temperature environment requirements
  • Special size and housing design to meet specific equipment installation requirements
  • Intelligent BMS integration for real-time monitoring and management
  • Regularly charge to avoid deep discharge
  • Keep the battery clean to avoid corrosion of the connection terminals
  • When storing for a long time, keep the power at 50%-60% and charge every 3 months
  • The storage environment needs to be dry and the temperature is moderate (recommended -10°C to 30°C).

This battery cell supports 1C continuous discharge (100A) and instantaneous discharge up to 3C (300A), which is suitable for high-power applications.

Under normal use conditions, the 20100 LiFePO4 battery cell can provide more than 3000 charge and discharge cycles, and the overall battery pack service life can reach 5~8 years.

Yes. The maximum charging rate is 1C (100A), which significantly reduces charging time and is suitable for scenarios that require fast energy replenishment.

  • Use appropriate welding technology (such as laser welding)
  • Equipped with insulating gaskets to prevent short circuits
  • Use high-quality BMS to ensure safety

20100 LiFePO4 batteries are known for their high safety, resistance to thermal runaway and overload, and support stable operation under high voltage and high current conditions.

Yes. The large capacity and long life of this battery make it an ideal choice for energy storage systems, such as home or small commercial energy storage systems.

The MOQ is usually 100 pieces, but for customized needs, we can flexibly adjust according to specific circumstances.

Yes, we provide full range of technical support, including design consultation, BMS selection, enclosure customization and after-sales service.
