change over circuit for cpath machine

research as I am aware that going from 48v to 24 would create LOTS of heat

Why do I even try????

You'll need a switch-mode regulator that can handle 6 amps+ at 48 volts.

A linear regulator will convert excess voltage to heat:

Power dissipated = current × voltage_drop

This is true for ALL LINEAR REGULATORS.

A switch-mode regulator can be 90%+ efficient. Instead of converting 50%+ of the battery's energy to heat, the loss will be less than 10%.

But you have to pay attention to the starting current. Otherwise, this project, like my time, will go down the drain.

And figure out how to turn off the humidifier.

This may do the trick for you. No guarantees from me.

Some work as you say. Many are heated, as is the one in this discussion (apparently).

He could put his linear regulator in the humidifier water and kill 2 birds with one stone.

going to reevaluate this whole mess.
leaning towards just buying a prebuilt unit
