In this video I will show you how we can use the classic LM3914 IC to create an LED Battery Level Indicator. Along the way I will show you how the IC works and explain why it is not the most precise circuit for a Li-Ion battery pack. And at the end I will show you how I created my own, more precise Battery Level Indicator circuit with a couple of simple components.
