Lithium Battery Charger Protection Module (BMS) 5S 15A 21V

  • 5S 15A PCM/PCB/BMS for 18.5V Li ion lithium battery pack
  • It is a Battery Management System for 18650 Lithium Ion 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 3.7V rated Li-ion 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.
  • 5S 15A BMS Charge protection Circuit
  • Common Port for charge/discharge
  • Voltage: 18.5V
  • Charge Current: 15A
  • Discharge Current: 15A
  • Can be used in 3.7V rated Li-ION Battery not for 3.2V Rated LiFePO4
  • The circuit is simple and reliable.
  • Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged.
  • Over current and short circuit protection .
  • Long time short circuit of the load won’t affect the PCB and the battery.
  • Model: 5S (3.7V rated Li-ION Battery not for 3.2V Rated LiFePO4)
  • 5S 18.5V15A bms is used for 5 series 18.5V battery pack
  • Common Version : common port for charge/discharge
  • constant discharge current: 15A
  • Charge Current: 15A
  • Dimension: 88mm*17mm*3mm
  • Extreme low power consumption. The consumption of the whole device is less than 50uA.
