      It appears to be V28.1.
      I was sent SPBMS16SRPV1.10.39.VIC.bin, but it won’t go through via the Victron VRM.”>Hello,

        Your battery firmware is too old to support VRM updates. To enable this in the future, you need:

        ● Battery V5 firmware v10.35 or above

        ● VRM software v3.80 or later

        ● Stable power to Cerbo GX during the update(consider in offgrid with no PVavailable)

        For now, please perform the upgrade using the BMS software. Once updated, future updates can be done via VRM.

        Let us know if you need assistance.
