Arduino based Battery Over Discharge Protection Circuit

In this post, we are going to construct a over discharge protection circuit for 12v battery using Arduino   which can protect 12V SLA battery against over discharge, and also protect the connected load from over voltage in case of overcharged battery is connected.   Understanding Battery Charge/Discharge Rates All the batteries have natural decline, … Read moreArduino based Battery Over Discharge Protection Circuit

Battery Full Charge Indicator Circuit using Two Transistors

This little circuit will alert the user regarding a battery reaching its full-charge level (over charge) while it’s being charged, by illuminating an LED. The circuit uses just a couple of transistors as the main active components. Main Feature The main feature of this design is not only its mini design but also its supply … Read moreBattery Full Charge Indicator Circuit using Two Transistors
