8S 20A Lithium Polymer BMS Battery Protection Board

PCM without balance + balance board = PCM with balance function

Two Version

  • 8S 20A   no balance  :    just a 8S BMS board,   without balance function. 
  • 8S 20A with balance :   8S BMS board   add  a 8S balance board

Aplications of 8S 20A Lithium Polymer BMS Battery Protection Board

  • 8S lipo batteries rechargables
  • Shilly-car
  • Drift car
  • Electric cars

Features Of 8S 20A Lithium Polymer BMS Battery Protection Board

  • High-accuracy voltage detection circuit.
  • Terminal of the charger using high voltage device.
  • Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit).
  • MOS transistor can control the battery charge and discharge.
  • Low standby current consumption.

Parameters Of 8S 20A Lithium Polymer BMS Battery Protection Board

  • Over Charge voltage : 4.25v±0.05v
  • Over Discharge voltage : 2.5v±0.02v
  • Over current : 100A
  • Continuous current : 20A           
  • Short Cut : Protectable, Charge can repair
  • There are 10 singal wires, if you make 4S battery pack, you can just connect 4 wires.
  • it max can make 10S battery pack.

This board can use as  4S/20A,  5S/20A, 6S/20A, 7S/20A, 8S/20A, 9S/20A, 10S/20A PCM.

  • 4S/20A    charge voltage is 4.2V*4=16.8V
  • 5S/20A    charge voltage is 4.2V*5=21V
  • 6S/20A    charge voltage is 4.2V*6=25.2V
  • 7S/20A    charge voltage is 4.2V*7=29.4V
  • 8S/20A    charge voltage is 4.2V*8=33.6V
  • 9S/20A    charge voltage is 4.2V*9=37.8V
  • 10S/20A   charge voltage is 4.2V*10=42V

Note :There are two connections ways :

  • Charge/discharge with different ports:

                                                         "P-" is the discharge negative end,"P+"is the discharge positive end.

                                                         " C-" is the charge negative end,   "P+" is the charge positive end.                                                                                                               Charge current is 10A;Discharge current is 20A.

  • Charge/discharge with the same ports:

                                                       " C- " is the charge/discharge negative end.

                                                       " P+  "is the charge/discharge positive end .

                                                       Charge/discharge current is
