@anthonyevs found @Coulomb notes, i think it may be invaluable to you. He has actually reversed engineered both hardware and software. He is serious guru, our most valuable human resource, if i may.!

Hi @anthonyevs ok i dont have soltaro battery bur i do have experience with canbus of livolyek. While there are some indications from members that these two come from the same stable and share protocol, i have some doubts about that. @Coulombhad partially reversed engineer the solaro protocol (SOL) and from what i see the canbus identifiers are different to livoltek to start with. Below is an extract from one of his responses on this thtead ;

 can do better now. Colleagues and I have confirmed that an Axpert MAX (which has a similar, perhaps identical removable display to the Axpert MKS III: removable display firmware version 12.11) on battery type SOL speaks CAN bus at 500 kbps with the protocol I documented (at least for the CAN IDs 0x1872 and 0x1874). It's not finished yet, but we demonstrated setting the SOC to 100%, warning 61 goes away, the battery icon flashes, etc. We could not demonstrate WEC protocol, as the BMS could not easily be set to 100 kbps.

I will have to search for his forum notes and provide link for you. 
.. To be continued... 
 

Existing firmware already has support for CAN comms to battery BMSs, in the WEC (Weco) and SOL (Soltaro) battery types, as far as I know. I've not heard of anyone using them though.
Are there more battery types now that use CAN comms?
The RGB thing just seems silly to me. Marketing gone mad.
