Looks like the new version changed the allowed unit of measure for the device class battery to be percentage only so you'll to manually edit the configuration.yaml file to change the device class battery to voltage. The easiest way to do this is (use the search tool) search for the word 'battery' and replace it with 'voltage'. There is also a change in the device class temperature. Do a search for the word 'temperature' and look in that section for the unit of measure,. you will need to change C to °C or F to °F. After you made the changes to all the occurances, then save. Then go to Developer Tools and select restart. Once restarted, select the 'manually configured MQTT entities' in the YAML configuration reloading section.

Thank you for the prompt answer. I have changed the device class in the configuration file like you suggested from battery to voltage. Reloaded the configuration and have restarted the HA, but the same error still persist.

That is strange. It worked for me. Make sure all occurances of battery are change to voltage and I think I selected restart first and then select the 'manually configured MQTT entities'. You can check to see if each entity was changed by going to Settings, Devices & Services, select the entities tab and look for the entity.. The icon should be a sine wave to indicate voltage class instead of the battery icon. If it is still the battery icon, then something didn't update.
