Hi, everyone. I haven't posted here in a while, and frankly I lost interest in it.
Going through some old projects and I thought I'd toss this one out to see if there might be enough interest to pick the project back up and finish it.
This is a battery monitor that checks the voltage of 6V batteries and displays the result on a moving bar (or dot) LED display. The voltage is expanded, so you see 5.5V on the low end and 7.5V on the high end. There are 8 individual monitors so it will cover a 48V nominal battery.
The circuit monitors the voltage and if a under voltage event occurs, a stand along LED will indicate it. The monitor will also let you know if you have AC power available from the grid or inverter.
