I read somewhere that people use the ‘engine starting’ feature of their automotive battery charger, to charge their battery bank faster (more amps) than regular charging. Is this something that should be done? My batteries are 12v 200ah 30amp gel Renogy brand. Also, someone said I don’t need to worry about the amp limit on the battery bank, because it is per battery, so in my case, I can charge them at 180amps safely, using multiple charge controllers or combined with a bulk charger. Is this something that others do?
