Hi everyone I want to build a low voltage detector for 12 volt batteries, this is for stand by equipment, generators, welders, light towers. My thinking is if the battery drops below 8 volts on startup then the battery needs to be pulled and charged then tested. The current draw before it detects a low voltage occurrence has to be under 1mA. When the battery dips below 8 volts a red LED will flash every 5 seconds, the detector will not reset until it is powered down and up again. I was going to start with these parts, a blinking LED and a voltage detector, from there I need some way to latch the LED on until it is reset by disconnecting it. http://elexp.com/a_data/08L36BID_08L36BGD_08L36BYD.pdf http://ww1.microchip.com/downloads/en/DeviceDoc/21434h.pdf First is there better components to use to do this project and how do I latch it on when it dose detect a low voltage.
