Slave Module Expansion Board for LFP BMS Starter Kit, 4-cell string (V6)

Your Price: From $106.00 to $122.50

Product Options

For Battery:


BMS-EL-V6/BMS200-EL-V6 is a string of four sense boards connected in a daisy chain. Each sense board is to be mounted on top of a Li-ion cell, and it measures voltage and temperature of the cell. Cell balancing function is built in. Voltage and temperature results are fed to the computer unit through daisy chain connection. The cell types supported are  LFP-G4S40Ah, LFP-G4S60Ah, LFP-G4S100Ah or LFP-G4S200Ah cells. The 4-cell strings can be further chained together extending the number of cells within a pack up to 140 in series.

The Battery Management System(BMS) are sold separately.

This version(V6) of sense board strings is best suited for pack voltage of 60V or higher. If you need sense boards for 48V or below, please check our BMS-EL (V2)

LiFePO4 Battery 40Ah, 60Ah, 100Ah 200Ah

This sense boards need to work with the BMS system.

  - 1x BMS-EP128 (no CAN OR with CAN).
    The difference between the two CPU systems is without or with CAN communication
    option. Both systems include a system computer, a shunt sensor for pack current
    measurement and a cable connecting the CPU to daisy chain of 4-cell strings.
  - A number of BMS-EL, BMS-EL-V6 or BMS200-EL-V6 sense board strings.
    Each sense board string contains four sense boards connected as a 4-cell string.
    BMS-EL and BMS-EL-V6 strings are for 40Ah, 60Ah and 100Ah cells.
    BMS200-EL-V6 strings are for 200Ah cells. BMS-EL sense board strings
    support up to a 16-cell (48V) pack. BMS-EL-V6 and BMS200-EL-V6 sense
    board strings support up to a 140-cell (500V) pack. If you have a 60-cell 100Ah
    pack, you will need 15x BMS-EL-V6 strings to be daisy chained together.

Battery Management System (BMS) Overview

The Battery Management System is designed for Li-ion battery pack using LFP-G4S40Ah, LFP-G4S60Ah, LFP-G4S100Ah or LFP-G4S200Ah cells. The system components include a CPU,  boards (connected as a daisy chain), a cable connecting the boards to the CPU, a shunt sensor and an LCD screen. The features of the Battery Management System are:

  - Designed for battery packs using LFP-G4S40Ah, LFP-G4S60Ah, LFP-G4S100Ah or LFP-G4S200Ah cells
  - A distributed system measuring voltage and temperature of each Li-ion cell
  - Daisy chain connection supporting up to 140 cells
  - Cell balancing
  - Integrated Ground Fault Detection and alarm output
  - Pack voltage measurement
  - Pack SOC calculation
  - Low voltage and high voltage alarm cutoff outputs
  - Optional CAN communication output
  - Composite video output
  - Made in the U.S.A.
