I'm an electrical idiot.
That's the issue.
I beg to differ. As a teenager I once tried to replace an element on an electric stove. Forgot to un-plug it. It was connected to a dryer-type "holes" which in Euroland would mean at least 220V, maybe more with the phases and what not.
The current ran between my elbow and my finger and I'm still horrified about that experience and how it could have ended for me.
The battery is DC, you'll be fine
