So, what kind of LED do you have, and what color is it? label should probably be something like
notify:green.

No space before A, for consistency.

I thought precharge is usually something low, because you are not yet sure of battery health...?

Are you sure? Normally systems shut down at 3.2V, 3V or so. Li-ion batteries don't
really like to be discharged _this_ deep.
