The MULi 6s Module is a sensor designed to monitor the Li-xx battery voltage, which measures the voltage of each battery cell via the balance connector. It allows you to monitor the voltage of up to 6 Li-xx cells per module. The individual MULi 6s modules can be serialized and can be connected to up to 5 modules. The MULi 6s Module sensor monitors the voltage of each battery cell with its history (minimum, maximum), the total battery voltage, the voltage difference between the strongest and the weakest cells, and the sensor is able to alert the operator to exceed the set parameters by means of alarms. Sensor information is transmitted by the Duplex system to the operator. 

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. For proper MULi6s function the transmitter version at least 2.20 (or newer) and the receiver version 3.14 (or newer) is necessary. Make sure that in the Devices folder of your SD card you have a configuration file "MULI6M.bin".
