As far as I know to get RS485 you need a JK RS485 module which plugs into the BMS( others have made one up ), I'm using one and works a treat communicating with victron multiplus-ii gx 48v 5000va

Ps I couldn't work out which one, contacted aliexpress seller I purchased BMS from and they confirmed the correct one for my as purchased BMS.

RS485 has 2 option:
- The dongle is a converter to RS485 and uses 9600 Baud per second speed.
- Using just the wires and no dongle it is serial > TTL which can go up to 115,000 Baud Rate.
Some vendors can provide the "wires only" wire with JST plug for the BMS but not all.
