4S 18A PCM/PCB/BMS for 12V LiFePO4 battery pack for electric bicycle and scooter and tools Battery Accessories. It is a Battery Management System for LiFePO4 Battery Pack.The main functions of BMS are over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection of Battery pack of 3.2V rated LiFePO4 Battery.It Uses top quality (A-level) protective integrated circuit IC,Strong load ability,use high voltage resistance,low inner resistance power Mosfet. The heat sink will greatly help cooling. IC itself has power balancing function.
Overview
  • 4S 18A BMS
  • Common Port for charge/discharge
  • Voltage: 12V
