        The main "issue" with whether a voltage is "dangerous" is whether it causes
a current flow through the heart of enough magnitude to cause trouble. At
12V it's pretty tough (but not impossible) to cause a large enough current
to flow through the heart to cause trouble. So, the question is: how high is
too high? That depends on so many factors it's impossible to consider a hard
cutoff line. FWIW generally 48V is considered "safe" enough in most
circumstances, however be warned that 48V can cause trouble, if the correct
circumstances occur. TTYL
