Hi @Arvian, Thank you for the update.
We have pushed BMS v1014.18 to your battery with version v1014.16. Please upgrade to the corresponding version of the battery.
However, batteries with BMS v1024.04 cannot be upgraded to BMS v1014.18. Please do not upgrade these batteries.
Good day @BLUETTI_CARE
Thanks for the reply and FW for my old battery
My question is not about to downgrade my newest battery from V1024.04 to 1014.18 but the working process itself: is it ok to have different versions of BMS even if this batteries are “Latest BMS firmware”?
As per my opinion all batteries must be the same BMS version no matter when it was sold. But as I understood - every batteries batch is somewhere different and number of BMS F/W is just a number and not the rule “bigger version number is better”
Hi @Arvian, We completely understand your point of view. However, it’s not feasible under the current circumstances.
Different batches of battery BMS come with different versions — 1024 is one version, while 1014 is another. There are also slight hardware differences between them. Different versions of firmware cannot be pushed to each other.
Of course, each version has its own latest and earliest firmware. This is simply a naming convention.
