I tested the colored bars and attached an image. The red fades in from below 2v, and just gets brighter as the voltage goes up. The blue lights only turn on at a specific voltage and above, from the controller chip.

Great product. I gonna use it for 3d printed case with 18650 battery pack for fpv goggles. Came faster than expected. Plastic can be trimmed on both sides to the width of the pdb board

Using it with an old 1S lipo and paired a push button, so the display is not on all the time. I also soldered a couple USB modules into the circuit to make an easy and cheap portable charging unit. Make sure to select the correct voltage when ordering, my first one I mistakenly bought 3S indicators. Both 1S & 3S versions work well, except I didn't notice any marks on the back to differentiate between the two. A sharpie can be used to easily mark the side of the display, or leave it in the bag until ready to use. 10/10

This meter was actually a lot bigger than I thought it would be. Will have to rethink my design for the battery box.
