FAQ

1833 lithium battery cells can be assembled into battery packs suitable for electric bicycles, portable devices and other fields, supporting a variety of voltage and capacity configurations to meet a wide range of application needs.

The voltage of the battery pack is determined by the number of cells in series (the voltage of each cell in a series is 3.7V), and the capacity is determined by the number of cells in parallel (the capacity of each parallel cell is 12Ah). For example, the voltage of a battery pack with 10 cells in series and 3 cells in parallel is 37V and the capacity is 36Ah.

Yes, a BMS must be installed after the battery pack is assembled. The BMS is responsible for monitoring and protecting the battery pack to prevent overcharging, over-discharging, over-current and over-temperature, extending battery life and ensuring safety.

  • Ensure that the battery cell voltage and capacity are consistent to avoid affecting battery performance due to imbalance.
  • Select an appropriate BMS to ensure that the parameters of the assembled battery pack are supported.
  • Use high-quality connectors and welding processes to ensure the stability and reliability of the battery pack.
  • Avoid mechanical shock or overheating of the battery cell during assembly.

The maximum discharge rate of the 1833 battery cell is 3C, so the maximum peak discharge current after assembling into a battery pack is 3C. For example, the maximum discharge current of a battery pack with a capacity of 36Ah can reach 108A.

The assembled battery pack supports a 1C charging rate. For example, the charging current of a 36Ah battery pack can reach 36A, depending on the selected charger and BMS.

The assembled battery pack can be discharged in an environment of -20°C to 60°C and charged in an environment of 0°C to 55°C. For extreme low temperatures, a heating system can be added to ensure that the battery starts at -30°C.

We support the assembled battery pack to meet a variety of international certification requirements, including UN38.3, CE, UL, IEC62133, etc., depending on the standard requirements of the target market.

  • Regularly check the BMS status of the battery pack to ensure normal operation.
  • Avoid deep discharge, it is recommended to keep the power above 50%.
  • Before long-term storage, keep the battery power at 50%-60%, and perform charging maintenance every 3 months.
  • Ensure that the storage environment is dry and ventilated, and avoid high temperature and high humidity.
  • We can provide the following customized services according to customer needs:
  • Adjust the voltage and capacity configuration of the battery pack
  • Equipped with customized BMS and heating system
  • Provide shell protection design, such as IP65 waterproof level
  • Support OEM/ODM services to meet the needs of specific application scenarios

Under standard working conditions, the battery pack supports more than 2000 charge and discharge cycles, and the service life can reach 5 years, depending on the usage scenario and maintenance.

Yes, we provide comprehensive technical support for the design, assembly and certification of battery packs, including battery selection, BMS selection, testing and optimization services to ensure that customers get high-performance and reliable solutions.
