Description
3s Li-Ion Battery Voltage Indicator
Based on LM3914N LED indicator IC
This project is using 5 LEDs instead of full 10pcs. Once you have calibrated the resistance value with a potentiometer, then you can remove it, measure it and place the measured resistance into "R_FIXED" axial resistor pads.
The PCB is fitted with 375mA fuse in case something becomes shorted. Also switch can be placed to the terminal block to take a measurement when you have connected this PCB to a battery with 2-pin JST connector.
