Li-ion / 18650 7.4V 2-Cells Battery Charger Protection PCB Board (up-to 5-Amps Peak Current)

  • RM6.00

  • Product Code: Li-Po 2-cell protection module
  • Availability: In Stock

 

This Li-ion / 18650 battery protection PCB protect a Li-ion / 18650 batteries with 3A 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.

 

Features

  • 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
