 BMS 5S 18/21V 20A 18650 Li-Ion Lithium Battery Charger Charging Protection Board Circuit PCM Balancer Power Bank Charger Module


Features:
 
 
  • The protection board is for 5 series Li-ion batteries, mainly used for electric power tools.

  • It uses special IC for 5S lithium batteries as processor to detect real-time voltage, charge and discharge current and ambient temperature of each battery.

  • Stable various protective functions for charging and discharging, such as overcharge protection, over-discharge protection and short circuit protection.

  • Low power consumption,the working current is about 25uA and quiescent current is about 6uA.

  • Choosing the correct protection board and applying it appropriately is vital to the longevity your batteries.
