| - | - **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/ | + | - **Adaptive Maximum Charge Voltage |
| - **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/ | - **Charge Current Limit (CCL)** – this is the maximum current that the battery will accept at any given time stated in Amps.

| For LiTE batteries 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.
