I bought a second B300 battery to add to my existing AC300+B300 power station.
The existing AC300 and B300 both got firmware updates in the past which I successfully installed.
The new battery was offered a firmware update which I also installed.
According to the app. Everything is at the latest versions. But the firmware versions of my two B300 batteries are different. How come? Is this the result of different hardware revisions of the B300 batteries I have?
My AC300:
S/N AC3002217000320982
IOT: v9014,12
ARM: v4037,07
DSP: v4036,30
Old B300:
S/N: 70700Z22330727
BMS: v1021,11 (Up to date)
New B300:
S/N: 30395Z22120351
BMS: v1014,16 (Up to date)
Hi @TheQuickFox, The BMS version start with 1014 and 1021 involve different hardware batches, so the latest firmware versions are also different, but there is no functional difference between them. The version number is simply a naming scheme.
The same applies to ARM or other firmware. These are separate firmware versions renamed based on hardware and batch differences, but each version has the latest firmware.

Thanks! That explains everything I needed to know.
@BLUETTI_CARE I would suggest to mention the hardware revision in the app and on the product otherwise users will keep getting confused why users get different firmware versions for devices the user thinks are exactly the same.
Hi @TheQuickFox, Thank you for your feedback. Your suggestions are indeed valuable.
We have forwarded them to the R&D team and are exploring the feasibility of updating the user manual and the app.
