Product Description

Heated Lithium Battery 7.4V 2s2p 4400mAh 18650 Rechargeable Li-ion Battery Pack

Model: 2S2P

Nominal Voltage: 7.4V

Nominal Capacity: 4400mAh

Size: 22mm*69mm*87mm

Max Charge Current: 0.5C

Charging Method: Constant current 1C to 8.4V, then charge with constant voltage 8.4V until charge current is less than 0.01C

Max Discharge Current: 1C

Discharge Cut-off Voltage: 6V, the over-discharge detection voltage of PCM

Operating Environment:

  • Charging: 0°C ~ 45°C ; 65±20%RH
  • Discharging: -20°C~60°C ; 65±20%RH

Storage Environment: -20°C~45°; 65±20%RH

Lifespan (80% Prime Capacity): >500times

Charging Attention: It is dangerous to charge with higher current or voltage than Product Specification may cause damage to the cell electrical, mechanical safety performance.

Advantages
  • Performance in Cold Environments: Maintains better discharge capacity in cold temperatures compared to traditional Li-ion batteries.
  • Enhanced Discharge Capacity: Keeps capacity at 80-90% of normal capacity even at -20°C.
  • Improved Voltage Stability: Provides more consistent voltage supply in cold conditions.
  • Safety and Longevity:
  • Reduced Risk of Damage: Prevents lithium plating on the anode, increasing safety and lifespan.
  • Extended Battery Life: Slows down degradation process, extending number of charge-discharge cycles.
Versatility and Adaptability
  • Wider Range of Applications: Suitable for outdoor applications in winter sports equipment, cold-storage logistics devices, and remote-area power supplies.
  • Adaptive to Temperature Fluctuations: Automatically adjusts heating intensity according to ambient temperature.
