Hello. I plan to use two identical devices in my project - Skylla TG-24/100 3 Phase. One for charging two lead-in-series lead-acid batteries of 12 volts 190 Ah each, the other as a constant power source, with the possibility of quick replacement of one with the other.
What resistance should be installed between the + POT and -POT terminals in order to limit the charging current to 20 amperes?
