Welcome to all technology science lover in this web.
All battery level indicator come with lot of price and much bigger circuit and more component need.
Now this is too much cheap and , affordable and very simple to make and only need 1k resistance and 6 leds (choose your color for make best) and cardboard ( use for circuit) connect them all using followed by the circuit diagram. You can change voltage level by changing the resistance in this circuit.
Thanks for all in web this project generally used for all drone battery, SMPS power, Robot and much more.
