 It is essential to use the BMS-Can (500 kbit/s) connection type of a [[venus-os:start|GX device]] with these batteries for communication of charge and discharge limits, error codes and state of charge.
-Use a Victron Type A VE.CAN to BMS-Can cable to connect the GX device to the battery. The VE.Can labelled end of the cable should be connected to the GX device, even if using a BMS-Can labeled port on a GX device. The BMS-Can labeled end of the cable should be connected to the battery.
+Use a Victron Type B VE.CAN to BMS-Can cable to connect the GX device to the battery. The VE.Can labelled end of the cable should be connected to the GX device, even if using a BMS-Can labeled port on a GX device. The BMS-Can labeled end of the cable should be connected to the battery.
 It is possible to use either the BMS-Can or VE.Can ports with this battery. Depending which one you use will require additional configuration on the batteries side, please see the documentation linked below for instructions.

+==== 3.1 GX Information  ====
+The Leoch BMS provides Minimum and maximum cell voltage and temperature information to the GX device.
+{{:battery_compatibility:leoch_min_max.jpg?400|}}
+The prefix to the minimum and maximum values is an identifier.
+  * Lowest Cell Voltage: “2::13”,”3.358V” that means the address 2 battery, cell 13 is the Min cell Voltage, and it is 3.358V.
+  * Highest Cell Voltage: “1::16”,”3.398V” that means the address 1 battery, cell 16 is the Max cell Voltage, and it is 3.398V.
+  * Min Cell temperature: “2::6”,”21°C” that means the address 2 battery, cell 6 is the Min cell temperature, and it is 21°C.
+  * Max Cell temperature: “1::2”,”35°C” that means the address 1 battery, cell 2 is the Max cell temperature, and it is 35°C.
