DC - DC Battery Charging Using a Charge Controller
I've found DC-DC battery chargers to be quite expensive (>$500 for a 24V-12V 5A charger) but I need one for an off-grid solar application. I had an idea to use a small 12 V solar charge controller (because they are cheap and readily available) between the 24 V source (in this case a 24 V battery bank) and a 12 V lead acid battery. Would that work? Or would its just burn out the charge controller?
