18650 Lithium Battery Protection Board 12S Slave Board Based on ENNOID-BMS | MKBMS LTC6811-12W-AL Slave Board

Sale price$114.99


MKBMS is based on the modular BMS of LTC68XX and STM32 MCU, and is connected to one or more slave boards and integrated integrated boards of different sizes through the ISOSPI interface. The modular BMS can be configured for various applications with battery voltages within 150V.

MKBMS is developed based on the open source materials of DieBieMS and ENNOID BMS. Currently MKBMS is compatible with ENNOID firmware. Here, a special thanks to the developers of open source BMS materials.


  • MKBMS slave board is made of aluminum base plate, which has better heat dissipation effect.
  • Scalable & isolated 1000VDC+
  • Compatible with MKBMS Master boards
  • From 5 to 18 cell levels monitoring per board
  • Daisychain Master/Slave ISOSPI communication
  • Parameters fully programmable through an easy to use graphical user interface
  • 33 ohm balance resistors (0.125A capacity) on all channels
  • Self powered by monitored cells
  • 1.2mV accuracy, -40 to 120C operation
  • Extra low power consumption (Sleep mode = 6uA)
  • Molex SL horizontal connectors for balance & temperature. (Comes with male, female + crimps)

      LTC6811 : Up to 12 cells voltage monitoring & 1+4 temperature sensors* per slave
     * The first temperature channel is used by slave board, the following 4 temperature sensors are not included in the package list but means an interface to connect 4 temperature sensors at most.
