Just received a new B300 today to add to my AC300 and 3 other B300s…
The BMS will not update
The BMS shows not online
The battery arrived at 63% while my other previous 3 arrived almost fully charged.
This new battery is at BMS v1014.13
All other batteries currently are at BMS v1014.15
When I click “CHECK FOR UPDATE”
I receive this message for all batteries: “No new firmware version”
Never had this issue with the others.
Any idea what I need to do?
Sent multiple messages to Bluetti.
Called multiple times with all but the logistics voicemail mailboxes full.
The logistics person was Out of Office too.
In 2 days, it will have been 2 weeks with no response. Unacceptable.
I expect with the thousands I have invested with this company’s products,
they could at the very least, respond.
I will update when/if I receive a response from them.
This is not looking good for any further purchases from Bluetti.
I received an answer yesterday (which didn’t address the main issue of concern at all).
The response was, “The upgrade option will only be released when the unit needs to be upgraded. So your new B300 has no this option because it does not need to be upgraded. And that is normal when the unit arrives only has 63% battery.”
Fine on the charge however, I have 3 other B300s attached to the same AC300 with the 3 original B300 batteries at BMSv 1014.15 and this one singular new one at 1014.13…
This response makes no sense…
Hi @djpcal , The two versions of B300 are different to distinguish between different original suppliers. In fact, the functions and parameters inside are the same.
These have been tested by the laboratory. Please feel free to use. If any problems arise during using B300, you can contact our support department. Thanks!
Upon receiving (around a year ago), my AC300 and 3 original B300 batteries, all 3 were at v1014.13 BMS. Immediately upon install, they updated to v1014.15 BMS.
Your statement would make sense to me had I not performed an update a year ago on the other 3 original berries. Hence, this is confusing to me that this is in regard to original suppliers and that this singular Newly Added Battery should remain at an apparently older firmware version by this numbering system.
If I recall correctly. that v1014.15 update was released to resolve an issue that some users were reporting at release with either minor incremental drain in standby or minor incorrect reporting of charge % of the battery to the AC300 interface.
Just trying to get full clarity on this as everything with the original setup at v1014.15 is and has been working flawlessly and I want this new battery to do be doing so as well and to clarify for other community members that may also encounter this with their setups. Thanks!
Has there been a resolution to this?
I ordered a new battery just before Hurricane Ian came here to Southwest Florida.
I’m thankful that I have the additional batter, BUT it doesn’t seem to be working.
It is stuck on 63% and always says “Offline”
I do have alarm warnings that won’t clear for me.
