Key Features & Advantages
  • Direct Charge & Discharge at Extreme Low Temperatures: No pre-heating required — capable of charging at -30°C and discharging at -50°C.
  • High-Power Low-Temperature Output: Supports 10C continuous discharge below -20°C with >90% efficiency.
  • Fast Charging above 0°C: 3C rapid charging capability for reduced downtime in warmer conditions.
  • Military-Grade Reliability at Civilian Prices: Extreme durability and robust cycle life (2000 cycles @ 80% DOD) without premium cost.
APPLICATION SCOPE: Off-grid solar storage in arctic regions, EV auxiliary batteries, telecom backup in extreme climates, polar research equipment, cold-chain logistics, and portable power for winter sports.
PACKAGING: Anti-static plastic trays (50 cells per tray, 200 cells per master carton). Insulated terminal covers included for safe transport.
IMPORTANT NOTICE: For charging at -30°C, use the recommended CC-CV profile with a reduced charge current (≤0.2C). The cell will not accept charge below -30°C. Always pair with a low-temperature BMS that enables charging only when cell temperature is within safe limits.

This lithium iron phosphate cell requires charging within -30°C to 60°C and discharging within -50°C to 60°C. It must be paired with a low-temperature BMS that restricts charging to safe temperature ranges to prevent damage.

  • Charge Temperature Constraint: The cell will not accept charge below -30°C and must be charged using a CC-CV profile with a reduced current of ≤0.2C at -30°C.
  • Discharge Voltage Limits: Minimum discharge voltage is 2.00V above -20°C and 1.50V at or below -20°C to prevent over-discharge.
  • BMS Requirement: Always pair the cell with a low-temperature BMS that enables charging only when the cell temperature is within safe limits.
  • Packaging and Handling: Cells are shipped in anti-static plastic trays with insulated terminal covers to prevent short circuits during transport and storage.
  • Current Limits: Maximum charge current is 3.0C above 0°C, 0.5C at or below 0°C, and 0.2C at or below -20°C.

This procedure describes the safe handling and charging of the ATOMFAIR 26650 low-temperature LFP battery. Follow these steps to ensure proper operation in extreme cold conditions.

Required Equipment: Low-Temperature BMS, CC-CV Charger

  1. Inspect Packaging
    Inspect the cell packaging for damage and ensure insulated terminal covers are intact.
  2. Verify Cell Temperature
    Verify that the cell temperature is above -30°C before connecting to a charger.
  3. Pair with BMS
    Pair the cell with a low-temperature BMS that enables charging only when the cell temperature is within safe limits.
  4. Set Charger Profile
    Set the charger to a CC-CV profile with a reduced charge current of ≤0.2C for charging at -30°C.

How does the maximum continuous discharge current of the ATOMFAIR 26650 LFP cell change at temperatures below -20°C?

At temperatures above -20°C, the cell supports 10C continuous discharge. Below -20°C, the maximum continuous discharge current is reduced to 7.0C to maintain safe operation and performance. This is directly stated in the product specifications: 'Max. Continuous Discharge Current: 10C @ T > -20°C; 7.0C @ T ≤ -20°C'.

What charging profile and BMS requirements are necessary for charging this low-temperature LFP cell at -30°C?

For charging at -30°C, a CC-CV profile must be used with a reduced charge current of ≤0.2C. The cell will not accept charge below -30°C. It is mandatory to pair the cell with a low-temperature BMS that enables charging only when the cell temperature is within safe limits, as stated in the product notice.

What are the minimum discharge voltage limits for the ATOMFAIR 26650 LFP cell at different operating temperatures?

The minimum discharge voltage depends on temperature: above -20°C, the limit is 2.00V; at or below -20°C, the limit is 1.50V. This information is provided in the technical specifications table to prevent over-discharge damage in extreme cold.

The ATOMFAIR 26650 LFP cell delivers 3000mAh capacity with extreme low-temperature operation down to -50°C discharge and -30°C charge without external heating, making it suitable for arctic energy storage and cold-chain logistics applications.

Positive

  • Direct cold-temperature operation: Charges at -30°C and discharges at -50°C without external heating, eliminating the need for battery warmers in extreme winter environments.
  • High-rate low-temperature discharge: Supports 10C continuous discharge with >90% efficiency at temperatures below -20°C, providing high power output in cold conditions.

Trade-offs

  • Reduced charge rate at low temperatures: At -30°C, charge current must be limited to ≤0.2C using a CC-CV profile; charge current is also restricted to 0.5C at temperatures below 0°C, requiring longer charging times in cold conditions.
  • Requires low-temperature BMS integration: The cell cannot accept charge below -30°C and must be paired with a low-temperature BMS that enables charging only when cell temperature is within safe limits, adding system complexity.
