I need help creating an LM3914 voltage meter (in bar mode). I looked at the datasheet and understand how to create a standard voltmeter (0-5V for example). However, what I need is an expanded range meter, and the datasheet seems a bit confusing about that.
To be precise, I need the circuit to meter a 4S lithium polymer battery. The voltage range has to be 12 - 16,8V.

I would appreciate any help,
thanks.
