This would be for a DC setup such as on a boat to help manage a starting bank and a multi bank battery charger.
Right now the boat charger charges every bank all the time forever. But a starter bank only needs charging if the battery is down below a voltage threshold of say 12.45v. Idea would be detect that battery voltage, then close the relay to the charger output for the starter battery bank if it falls as that shows the battery needs charging, have it run for a period of selectable time, then turn off and remonitor the starter battery.
does such a device already exist? I think I have burned up the starter battery as the charger just slowly cooks off the water, and the battery was sealed so cant add any water. Your car does not have to be plugged into a charger all the time, so why do that for the boat starter battery, it just gets it used up. Of course battery sellers want you to buy a new battery every couple of years... This idea here is an opportunity, I dont think anyone has such a thing yet, likely it would sell. You dont keep your car plugged in all the time on a charger, if you have to do that, the battery is bad.
