There doesn’t seem to be a clear consistent answer, the manual implies “a little over” is OK but does not define “little”. I admit that I don’t understand how a device that can handle 12v can’t go over 9v.

I do know that I have made contacts quite well with just 2 Lion 18750’s and they last for the duration of the park operation. ?The output is <4w, not a big deal.

Until we really know, just play it safe, many ways to keep the voltage under 9v.

You could put a small buck converter or a couple of diodes in the line to drop the voltage into acceptable range.
