I have already checked for firmware updates using the BLUETTI app via Bluetooth connection, but the app shows that the device is already up to date and no updates are available.
Please push the latest available firmware for the AC300 and all connected B300 batteries so the system can be fully updated and synchronized.
The device is powered on, connected via Bluetooth, and ready for firmware upgrade.
Hi @tonino is there any particular reason you are looking for a new update? are you having any issues.
Is it battery pack 3 that you are looking to gat updated to the same as pack 1/2, it isn’t away possible to get the same version as it has a lot to do with the age of the batteries and different hardware that’s inside but If there is any custom firmware available bluetti will be able to push it to your unit. @BLUETTI_CARE
Remember it the Chinese new year at the moment so response time will take a bit longer at the moment.
Thank you for your reply. Yes, I’m having issues with my AC300 and one battery in particular. Even though the battery appears to be turned off, as soon as I connect it to the AC300 it powers the unit on. This seems to mean that it is still supplying current even when switched off.
My AC300 also shows error messages from time to time for no apparent reason, and then they disappear. This happens even when I am using the two other batteries that are working properly.
Thank you as well for reminding me about the Chinese New Year.
