The MULi6s EX sensor is used with a Duplex receiver to monitor the voltage of your (up to) 6 cell Lithium battery pack. The MULi6s EX will monitor the total pack voltage (up to 6 cells) as well as the voltage of each individual cell through the battery balance connector and also includes a user-defined low voltage alarm and an error alarm.

Through the Duplex 2.4GHz system and either a JetiBox Profi or Jeti Transmitter you can monitor all your battery voltage data and alarm conditions in real time.
