Lm3914 lead acid car battery monitor


Recommended Posts

I need to make a car battery monitor using the LM3914 ic.

led 1 = 10v, led 10 = 13.8v

what value resistors do I need?

i have a full stock of resistor values, 2x LM3914'S and 2x 10 led bar graph displays, but cant experiment and blow an IC.

I also have a good range of capacitors, diodes etc.
