I forgot to say, during my tests, I also tried 2 stage Peltier with 15x30 and 40x40, the problem is that the hot side is too hot and they need a large heat sink.
The main thing is not to have the too hot side, therefore find a compromise with the voltage.
The GND DC-DC converter is common with GND voltage, that way the Peltier is always controlled by VT1, just the positive leaving from the converter, I think this is the best solution.
