 Victron does not store ZYC firmware files on VRM, nor does it know what the latest firmware version is, or if there is an update available.  ZYC updates will need to be downloaded to your computer first from https://www.zycportal.com documentation section so that you can upload them via VRM.

 After completion, check the battery’s firmware version in VRM and monitor for any system issues. The VRM firmware update is applied to the Master battery, for large systems it can take some time for the ZYC BMS to then automatically update the firmware of the other connected batteries.
