I have 2 rechargable batteries at 1400 mAh each. I want to make a circuit with 3 LEDs that will show me the charge of the batteries i.e.: when they are almost discharged only the 1st LED will light, when they are medium charged the 1st and the 2nd LED will light and when they are at almost full charge all 3 LEDs will light. Need some ideas and help :? .
