hi ag,
The LM3914 is set up for Rlo =3V and Rhi at 4.2V.
The TS is measuring one nominal 4V cell, he does not need the divider.
The video used a 10K/10K divider as he was measuring two cell in series, ie: 6v thru 8.4v, the divider was used to drop pin#5 to 3V thru 4.2V

Was expecting an answer like this for the questions i had asked, tho it was obvious.
