You will need a Victron VE.Can to CAN-bus BMS cable.

For JK BMS inverter type you will need the Type B cable
Victron Part Number is ASS030720018 – VE.Can to CAN-bus BMS type B Cable 1.8m

Other batteries may require the Type A cable, and Ive even heard reports that the A cable has worked for some users. It is also possible to make your own.
