AC500 with B300S, B300K and B230

It is getting confusing which batteries are compatible with the various AC units and what mixes of battery types are supported.

As I understand it, on one of the AC500 ports I could attach any combination of B300S and B300K batteries daisy chained together. It’s also my understanding that the B230 could be attached to the AC500 but not at the end of a daisy chain with the B300S or B300K batteries.

AC500->B300S->B300K->B300K on one port and
AC500->B230 on a second port

but these would not be supported:
AC500->B300K->B300K->B230
or
AC500->B300S->B300S->B230

Is this correct?
