This is a beginners forum. The point here is to show the beginner what should be done prior to flight (and after each flight). We don't tend to overload a beginner with information that is, most likely, unapplicable to basic flight.

I totally agree that battery checks are essential, and that it should be done under load. I have always stated that the voltwatch, or whatever device that is used for a "quick look" at the battery condition is a good thing but that it should be done before a flying day begins with a loaded voltmeter.

I would venture to say that there are no beginners out there that are using a true digital servo.

The bottom line here is that the voltwatch, volt spy, whatever, is a good secondary device and many use them. I do, on everything I have, and rely on them to give me that quick look at battery condition. It saved my plane one time.
