Hey Everyone!
Better late than never… right?
If you are interested in the B300K expansion battery, please feel free to ask your questions.
I’ve also prepared another video for you.
Have a look if you like.

Seems I read that you can only add 4 of these batteries instead of 6 as with the B300s. Yea or nay?
.
Also, how that does work if you have split phase AC500s, with B300s on one and B300Ks on the other? Will they charge and discharge equally?
Hey @St8kout !
Thanks for your questions.
Yes, on their website they mentioned the use of 6x B300S, 2x B300S and 2x B300 or 4x B300. They dont exactly mention the B300K, but im sure its the same like B300.
In germany wen dont have this split phase feature, so i dont know how exactly it works. Maybe @BLUETTI or @BLUETTI_CARE could ask a team internal to solve this question.
greetings

Yes, the AC500 single unit can connect a maximum of 4 B300K batteries.
In split-phase mode with two AC500 units, one side can connect a B300S to output 4500W, while the other side with a B300K can only output 3000W. This is fine for smaller loads, but exceeding the power limit may cause errors.
For the sake of power balance, it is recommended to consider adding battery packs on each side in split-phase mode. If you don’t care about the imbalance between the main unit’s battery level and the slave unit’s battery level, then it doesn’t matter.
