I tested my 80% profile (limited to 25A) on a very hot 92 °F day. The chargers reached 65 °C but did not shut down due to overheating. (My 80% profile ends charging when the draw reaches 10A.)

A charger temp of 65 °C is still much hotter than I would like, so I don’t plan on charging in 90 °F heat very frequently.
