This battery series requires controlled storage and handling to prevent electrical and thermal hazards. Use only with a compatible BMS and adhere to voltage and temperature limits.

  • Storage Environment: Store cells in moisture‑barrier vacuum‑sealed packaging to prevent electrolyte degradation from humidity exposure.
  • Electrical Safety: Always operate the battery with a BMS that provides over‑discharge, over‑current, and cell balancing protection.
  • Voltage Compliance: Charge the battery only within the manufacturer’s recommended voltage range to avoid overvoltage damage.
  • Thermal Management: Avoid exposing cells to excessive temperatures for extended periods to prevent thermal runaway or capacity loss.
  • Discharge Limit: Do not exceed the rated peak discharge duration to prevent irreversible cell damage.

Follow these steps to safely initialize and operate the battery cells. Always comply with local regulations for disposal.

Required Equipment: Compatible Battery Management System (BMS)

  1. Pre-condition Cells
    Pre-condition new cells at a suitable temperature before first use.
  2. Connect BMS
    Connect the battery to a compatible BMS with over-discharge, over-current, and cell balancing protection.
  3. Charge Battery
    Charge the battery within the manufacturer’s recommended voltage range.
  4. Monitor Temperature
    Monitor the battery temperature during operation and avoid exposing it to excessive temperatures for extended periods.
  5. Limit Discharge Duration

How does the semi-solid electrolyte in the ATOMFAIR 3.95V 250Wh/kg 25Ah series affect thermal stability and leakage risk compared to conventional liquid electrolyte pouch cells?

The semi-solid electrolyte enhances safety by reducing leakage risk and improving thermal stability, as stated in the product description. This is critical for high-rate applications like drones and robotics where pouch cell integrity under mechanical stress or elevated temperatures is a concern. The series supports 2C charge, 5C continuous discharge, and 10C peak discharge, indicating the electrolyte formulation maintains ionic conductivity under high current loads without compromising safety.

What are the voltage and dimensional constraints when integrating the AF3952506S, AF3952508S, AF3952512S, or AF3952518S configurations into a UAV or portable power station?

The series offers four configurations with cell voltages of 23.7V (6S), 31.6V (8S), 47.4V (12S), and 71.1V (18S), all with a nominal capacity of 25Ah and a cell voltage of 3.95V. Dimensions vary by model: the 6S measures 65.5×89×205 mm, the 8S 86.5×89×205 mm, the 12S 127.5×89×205 mm, and the 18S 190.5×89×205 mm, with weights from 2450g to 7000g. These parameters allow engineers to select a configuration matching the voltage bus and physical envelope of their system, but a compatible BMS with over-discharge, over-current, and cell balancing protection is mandatory.

What are the recommended storage and preconditioning requirements for the ATOMFAIR semi-solid battery series before first use?

The product notice states that new cells must be preconditioned at a suitable temperature before first use, and exposure to excessive temperatures for extended periods should be avoided. Cells are shipped in moisture-barrier vacuum-sealed aluminum foil bags inside anti-static cartons, indicating sensitivity to humidity and static discharge. For long-term storage, maintaining the manufacturer’s recommended voltage range and using a BMS with over-discharge protection is advised to prevent capacity degradation.

The ATOMFAIR 3.95V 250Wh/kg semi-solid battery series delivers 25Ah capacity with 5C continuous and 10C peak discharge rates, supporting high-energy-density applications such as drones and robotics. The semi-solid electrolyte enhances safety, but reliable operation requires a compatible BMS and strict thermal management.

Positive

  • High energy density (250 Wh/kg): Enables extended runtime in lightweight designs for UAVs, portable power stations, and robotics, directly reducing system mass while maintaining capacity.
  • High-rate capability (2C/5C/10C): Supports 2C fast charging, 5C continuous discharge, and 10C peak discharge, meeting power demands of high-drain electric equipment and drones.

Trade-offs

  • BMS integration mandatory: A compatible battery management system with over-discharge, over-current, and cell balancing protection is required to prevent damage and ensure safe cycling.
  • Temperature sensitivity and preconditioning: Cells must not be exposed to excessive temperatures for extended periods; new cells require preconditioning at a suitable temperature before first use.
