New BMS update?

Product Discussion Expansion Battery
1

updated to the new firmware, again today…
IoT: v9014.12
ARM: v4032.11
DSP: v4031.30
BMS: v1021.11
Question: Is there a BMS update? when I check the, “check for update,” it states I need to disconnect the solar panels, but doesn’t say there is an update?
Question #2: if there is an update, do i need to disconnect and re-attach each battery separately to the ac300 to update each individual battery as before?
Thanks

Hi @LukeWarm, Is there any issue with your B300 or AC300? If not, there’s no need to update the firmware.
We’ve found that the BMS firmware on your B300 is already up to date.
If a future update is needed, each B300 battery will need to be connected to the AC300 one at a time to update the BMS firmware individually.

Everything works great, just wondering if there was an update available for the batteries…it is a pain to unhook and then hook up each battery individually…Just sayin

Hi @LukeWarm, Thank you for your confirmation. We’re glad to hear everything is working great now.
Yes, when there are no issues, we usually recommend not upgrading. Updating the BMS can indeed be a bit troublesome, and we don’t want our customers to be caught up in unnecessary hassle.
