Which Li-Ion battery do you use for this device? Should I separate the battery from RAK 4630 (for example, by the unified enclosure mounting plate shown on the left above picture)?
I know it should have a voltage of 3.7V or higher and, of course, fit into this enclosure. However, I would rather ask about a concrete model that meets your expectations.
You should somehow separate the battery from the WisBlock.
Either below the mounting plate, or you fix it with doubles sided tape to the lid of the enclosure.
I usually add a second 3D printed mounting plate above the WisBlock.
We cannot suggest any specific battery model, as there are too many manufacturers and sometimes even the same battery is sold under different brands and names.
Generally any Li-Ion battery with 3.6 to 4.2 V will work.
