The 4.2v and 3.3v numbers apply to standard LiPos.
They would not be correct for a LiHV battery or a Liion battery, for example.

Not sure if we want to add the numbers for other chemistries, or just let the user look it up themselves?

yeah lets generalize a bit...thanks

Putting the e.g. was meant to mean the 4.2v is just an example. I've already got "of your batteries" so I'm not sure we need the extra bit as well?
Or should we change the "e.g." to "i.e.", so it makes at least a bit more sense?

eg is the correct term....."for the sake of example" in latin....ie is incorrect "in other words (id est....that is)"

I do know the difference between eg and ie, actually...
In fact, I was thinking precisely that "that is" would fit better than "for example".

If we're giving just one example - like just mentioning LiPos and nothing else as my original PR had, then "eg" would make sense.
But "4.2v x No. Cells for standard LiPos, or as appropriate if using a different battery type" is effectively all possible options, therefore "for example" doesn't make sense anymore and "that is" makes more sense.

I continue to disagree...examples of a statement use eg..restating the statement in simpler terms uses ie
