Can I stack Battery Module and Plus Unit at the same time?

Can I stack a Battery Module and a PLUS Unit at the same time?
I am worried because I looked at the caution in the document of Battery Module showing below.

CAUTION: Do not use this battery module at the same time as other batteries (such as the M5 Core bottom battery). At the same time, in the worst case, there is a danger of catching fire.

@isizakit Dangerous behavior!

Oh! I see.

Another similar question:
I have a M5Stack-Basic. So I want to stack a Battery Module with it.
But this is not good according to the CAUTION. Is this right?

Can I stack if I remove the battery included in the Bottom?

@isizakit Yes but the battery is not plugged into the base so you will need to unsolder it (or at least thats the way with my core.) please note that there is a battery connector on the back of the core.

@isizakit Yes, as @ajb2k3 said. To be careful.

@ajb2k3, @watson Thank you so much.
Uuum, stacking is very convenient but considering batteries is not convenient.
