1S 3.7V 3A Lithium Ion Battery Protection And Charging BMS Module

This is a 1S 3.7V 3A Lithium Ion BMS Module. This module is charging and protection module for Single Cell Lithium Ion or Lithium Polymer Battery. It provides the overcharge, over discharge and overcurrent protection. The charging voltage must be 4.2V. The module is very small in size and can be fixed directly with the battery. The 1S 3A Lithium Ion BMS Module starts the charge or discharge with some delay after the protection trigger has been removed.
