Li-ion / 18650 7.4V 2-Cells Battery Charger Protection PCB Board (up-to 8-Amps Current)

  • Was  RM7.00 
  • RM5.50

  • Product Code: BAT-CR/PR-2S-8A
  • Availability: In Stock


This Li-ion / 18650 battery protection PCB protect a Li-ion / 18650 batteries with 8A continuous current. Protection is critical as a Lithium-ion batteries could explode when they are shorted circuit or overcharged, and damaged when they are over discharged.



  • Over charging - Disconnect circuit when either battery is over 4.35V
  • Over discharging - Disconnect circuit when either battery is lower than 2.7V
  • Short curcuit protection - Disconnect when short circuit is detected
  • High-accuracy voltage detection circuit
  • Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit)
  • MOS transistor can control the battery charge and discharge
  • Low standby current consumption



  • Over charge voltage:4.25 – 4.35v  ±0.05v
  • Over dishcarge voltage: 2.5 – 3.0v  ±0.05v
  • Max continuous current: 8A
  • Max peak current: 15A
  • Working temperature: -40 ~ +50C
  • Storage Temperature: -40 ~ +80C
  • Small current: less than 3uA
  • Life-cycle: more than 50000hours
  • Resistance: Less than 300mΩ
  • Short cut protection: Protectable,charge can repair
