AC500-max batteries

I have an AC300 with 3-B300 batteries. I was wondering, if I upgrade to an AC500 what is the max mix of batteries that I can use? Since I have 3-B300s, will the AC500 only take one more B300, or if i continue to use the 3-B300s, can I use more than 1-B300s?
So the question is, what are the combinations that would work with the AC500 given the fact I already have 3-B300 batteries?
Thanks.

@LukeWarm
As long as there is a B300, single AC300/AC500 can connect to a maximum of 4 battery packs.
The standard battery pack for the AC500 is the B300S, and one AC500 can connect to a maximum of 6 B300S.

You already have 3*B300, so I suggest you purchase one more B300 or a B300K.

That’s not true !
I have 1x B300S, 1x300K and 4xB300 connected to my AC500 and they all show up and work great together.
You just need an adapter cable.

Yes, you’re right.
After confirming with the tech team, a mix of B300+B300K+B300S can be connected to the AC500, up to 6 packs when mixed.
But AC500 needs to connect B300 first, then B300K/B300S, so that it can recognise 6 packs, otherwise the system can only recognise 4 packs.

At this point I have a question about the arrangement of the batteries on top of each other.
Is it possible to permanently stack a tower with 4 batteries and the AC300 on top?
I’ve had it like this for a year and so far
there have been no stability problems.

I think that there is a metal frame under the plastic cover of the batteries that can bear the weight.
Unfortunately, Bluetti does not offer longer connection cables so that the batteries can be placed next to each other. I do not understand why.

Perhaps your development department could provide information.
Many thanks!

Side by side works for me. The big cables are flexible enough that I can put the two stacks far enough apart to easily manage the AC and DC input cables of the AC500.

I have an AC300 with 3 B300 batteries, and I stack them on top of each other on a rolling cart, which I never move.
I have 2 batteries stacked on top of each other, the AC300 on top of them, and then the third battery on top of the Ac300. I do lose the use of the wireless charging but I never use it. It seems fine…
if I get a fourth battery I would stack 3, then the AC300, then the fourth on top. I believe the units are manufactured to stack with this type of weight, but that does remain to be seen. I do not have the room to stack side by side.

I have AC500 + 4 B300S. Do I understand correctly that I can add one B300K? Limited by vertical size! In what order should I connect?

Of course it works.
The B300K only comes with a cable for connecting to an AC300 or B300.
For the AC500 or B300S you need an adapter cable.
It says so in the B300K manual.
