Description
I made this portable box to feed rail relays;
The box uses a step_up modulator powered by a 4.2V 18650 lithium battery; the voltage is adjustable by potentiometer, in output up to 50Vcc; there is a button to check the output voltage on the display or the battery voltage; There is a protection circuit for the battery and for charging via micro-usb
Here's what you need:
