AC500, B300, B300S Firmware Updates

How do you update the firmware etc in the new Bluetti app v2.1.3? I can not find a firmware update option or even the current firmware number anywhere.

Generally, the battery pack has no available firmware to update. If your host needs to be updated, please refer to the following steps. (Steps are the same as for AC500)

If there is no update available, your host has the latest firmware version.
