• 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)

      Variant:
      LTC6811 : Up to 12 cells voltage monitoring & 1+4 temperature sensors* per slave
      LTC6812 : Up to 15 cells voltage monitoring & 1+8 temperature sensors* per slave

      LTC6813 : Up to 18 cells voltage monitoring & 1+8 temperature sensors* per slave
     

*The first temperature channel is used by slave board itself.

The following 4 or 8 temperature sensors are not in the package lists

but means an interface to connect 4 temp sensors at most

or to connect 8 temp sensors at most.
