6S 20 A Li-ion Lithium Battery 24V 18650 Charger Protection Board Module is a small PCB mount Li-ion Lithium Battery charger protection module. This small battery charger protection module comes with various features like Short circuit protection, Overcharge protection, Over-discharge protection, Overcurrent protection. It is very easy to install and convenient to use in all your DIY portable projects.


  • Battery protection board is mainly for the rechargeable battery (generally refer to as lithium battery) to protect the role of the integrated circuit board.
  • Lithium battery (rechargeable) needs protection, which is determined by its own characteristics.
  • As the material of the lithium battery itself determines that it cannot overcharge, overflowing, short-circuiting, and super high temperature.
  • Charging and discharging of lithium battery will always follow a protective plate with a sampling resistance and a current safety device.
