Some unknown register IDs in PGN messages for Lynx Smart BMS

My team are developing an embedded system that talks to a few Victron devices, including two “Lynx Smart BMS”. We caught some of the broadcasting CAN messages from a Smart BMS device but found that some messages (register ID) are not listed in the Victron open documents (mainly VREGS). The register IDs of these messages are: 0x0386, 0x0389, 0x038A, 0x0390-0x0393, 0x2001, 0x2015, 0x210C, 0xEC43, 0xEE92, 0xEEFF.

I wonder if you can provide me with some documentation of a definition of the whole register list of the Smart BMS? That of “Orion XS 1400 DC-DC” and “Skyla IP65 AC-DC” are also high appreciated.
