Review on thirty by Stanislaw Kalinowski ᠌

Cannot handle 20 amps at room temperature. Overheats and turns off. Weak cooler. Stable holds only a current of 15 amperes. I think an additional fan can solve the problem if you fix it on the case cover. I bought it as another charger for agm batteries of a home autonomous system with a total capacity of 400A / h. While it comes in handy well, now two chargers together give 30 amperes. I use only the first mode - 14 volts.
