Two Different BMS Versions?

I have a new AC200MAX and a new B230 “Expansion” pack. Each seems to have different BMS “Versions”. Isn’t it best if they had the same BMS versions?

I believe your BMS has the most up to date firmware already on it. I don’t believe there is a 1018 update for the max. Likely exclusive to the b230.

That is correct.
1017.03 is the BMS from the AC200MAX
1018.02 is the BMS from the B230

My B230 just arrived last week with what seems to be a much much older BMS version…

Yes, that seems that way to me too. Perhaps you should talk to Bluetti to get it updated(?)
