You should always switch each device with a separate contact. Devices' inputs may be at different reference levels or open circuit Voltage levels.
If your BMS has only one output the use it to drive a relay with two separate contacts so that the contacts being used to enable /disable each device will be isolated.
You could also use a single output BMS to drive two opto-isolators if you would rather use those instead of a relay.
Thanks WKirby - I have ordered a seperate port BMS that doesnt switch off the charging current, Ill let you know how I get on.
