 The Freedom Lite transmits, amongst others, the following messages to the [[https://www.victronenergy.com/live/venus-os:start|GX-device]]:
-  - Adaptive Maximum Charge Voltage Set-point – the value transmitted varies from 54.8V to 55.8V depending on the state of balancing on the particular Lite. Typically a well-balanced Lite battery will request a maximum charge voltage of between 55.0V and 55.8V. This advanced feature is only available from Freedom Won and allows superior system control and optimal battery management. The GX-device uses this set-point to control the real time operating or target voltage of the inverter/charger devices and the MPPTs.

-  - Charge Current Limit (CCL) – this is the maximum current that the battery will accept at any given time stated in Amps. This is a secondary control feature behind the more effective maximum charge voltage control method. This value reduces as the battery approaches 100% State of Charge (SoC). The GX-device uses this value to ensure that the combined Victron system of inverter/chargers and MPPT’s does not exceed the CCL of the Lite. If the CCL drops to zero, the Victron system within a few seconds will ensure that there is no net current flow into the Lite.
-  - Discharge Current Limit (DCL) – this is the maximum discharge current that the battery is prepared to accept at any given time. This value typically decreases as the battery drops below 10% SoC. The Victron inverter cannot enforce a variable DCL unless in ESS mode were an AC input source can be used to supplement the power to the loads. If there is no AC input source the inverter will stop supplying power to the loads as soon as the DCL drops to zero.

 **Note:** In the case of the Venus GX or Octo GX, if the VE.CAN ports (RJ45) are being used by MPPTs, the secondary CAN bus needs to be connected using the green terminal blocks.  If you require any information on how to do this, contact Freedom Won support at support@freedomwon.co.za

 If multiple batteries are installed in parallel the second RJ45 socket is used to link the next battery in the line onto the CAN Bus network. The termination resistor is installed in the last battery in the CAN Bus line. Refer to Lite installation manual for further information.

+BatteryLife is mandatory for Freedom Lite batteries that are being cycled. This is to prevent long durations without the battery seeing 100% charge, and this in turn eliminates SoC drift issues that creep in after several days without the battery having reached 100% SoC.
