"It won't do any damage.  It just might not get you off the ground."

"It really depends on the size of your build.  Typically, most quads operate best at 12V and above (usually 3S or 4S).  Lower voltage means less power.  Less power means smaller motors and speed controllers and a smaller, lighter body.  You're…"
