Fancy 1-8 cell lithium battery level indicator

This is the more sophisticated battery level gauge than the earlier op-amp based one. It uses a microcontroller to do the level testing, and has solder-blob links for selecting from 1 to 8 cells. The design is refreshingly simple with a selectable voltage divider for different cell counts, and all the threshold detection done with software. Mid-play video-adverts are annoying in technical videos, so I don't enable them. If you appreciate that and enjoy my content then you can help support the channel with a contribution of a dollar or two a month on Patreon. That also lets you critique the (advert free) videos before they are released, gives a more direct means of communication with me and also gives access to the regular relaxed Patreon live streams.   / bigclive   #ElectronicsCreators
