    If closed-loop communications fail, preset open-loop (Comms Lost) values for XW PRO open-loop operation are selected by the Battery Type during the BMS Setup. LYNK II does not configure these settings; the values provided are only for reference. Many factors can influence DC voltage. State-of-Charge (SOC) is considered more reliable than DC voltage as a trigger value.

    Battery Bank Capacity This value must be set to the number of batteries in the (Ah) system multiplied by the rated capacity of the Discover Lithium battery. The battery model determines the capacity value: 130 A for a single 42-48-6650, 57 A for a single 44-48-3000, 30 A for a single DLP-GC2-48V, and 100 A for a single 48-48-5120.
