Is there a public document with a list of the EB3A firmware versions and their release dates? Even better would be if it also included a changelog for each update.
No, there is no public List of Updates and bluetti also provide no public changelog for their Powerstations yet.
Based on the factory date, sometimes the newest version differ, even for the same type of powerstation
That would be a helpful thing to have but in spite of repeated requests, for information relating to firmware updates, none has been forthcoming.
This would be helpful and all. after all i would want to know what has changed or will change before installing the update.
That is a good question and one that I have not seen an answer on
i did this request by myself. The only answer yet is, that there is no public changelog or patch history.
Sorry that i cant help you more than this
