5S Protection Board Li-Ion Lithium Battery Pack Protection Circuit Boards BMS Module Battery Protection Board For Power Tools


  • 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.
