18650 to 3V BMS
Tired of replacing CR2032 batteries into your connected objects ?
Here is a small that allows you to place a 18650 battery and provide 3V regulated output.
Do you want more ? It has a usb-c port to charge the battery when it's empty. Still more ? The circuit is protected from battery polarity inversion, short circuits and battery under/over voltage.
