CAN socket on latest Seplos revision has rs485

[archi]

Thanks for the project! And the Neey balancer one! (And for the generous FOSS work overall <3).

I have the latest revision of the Seplos 200A 48V 16S BMS (if the seller didn't lie - I haven't disassembled the battery far enough to verify). That one supports RS485 on the CAN socket. Pins are 1&2 (A: green, B: orange), did not test 7/8. Ground is disconnected.

Maybe you want to reflect this in your docs? Should I open a PR?

(I'm not sure if that's advertised anywhere, but I just realized that it shouldn't work when comparing my setup with that of a friend; though the Seplos advertises only half the charging current and I'm afraid that's because it thinks the esp is another charger).
