OK - talking about a different animal here JC - I was really only speaking regarding the lighting system. (and not for BAs, cos they do use the BEM for some of the lights)

Now, if your ESS is BEM operated you will definitely need to use the same voltage throughout - do not use battery voltage supply. Yes, you could use a 12 volt relay but it will draw more current - better to get a 5V one from tricky Dick Smithy's local electronics shop.
