Just picked up a AA-2 X and am very impressed with the output compared to my old AA-2 Neutral (Q3 XP-E) - and all out of a couple of Eneloops!
That said, I have a question about the thermal protection on my AA-2 X version vs the 123-2 X. My AA-2 X heats up noticeably faster on Turbo compared to the XP-E version and I wonder if the 123-2 X's temperature stabilizes after the drop-down considering it only drops to the initial Turbo output level of my AA-2 X model. Does the DC-DC boost circuit in my AA-2 X generate more heat than the buck circuit on the 123-2 X version? Does the 123-2 X have additional or improved heat-sinking compared to the AA-2 X? If there is no heat difference between the circuits and if the heat-sinking is the same as well, would it be safe to say that the 123-2 X will run noticeably hotter throughout its Turbo run compared to the AA-2 X?
